Does anyone know if the original promise of their simple layout model proved itself?
IIRC, the Flutter team mentioned how using just width/height constraints is enough to represent all relevant layouts. This sounds very nice, being so much simpler than Flexbox and miles ahead of CSS Grid ergonomics.
Did it live up to the promise or did they expand the model with Flex/Grid/etc?
The premise is a bit off. Flutter was never just width/height: the model is min/max box constraints. The core rule is: constraints go down, sizes come up, parent sets position.
Row and Column are just layout algorithms built on that same model, not separate engines added later. GridView uses the sliver system internally, but still doesn't require anything like CSS Grid's general layout model. The render API is open enough for custom layouts too, so packages like https://pub.dev/packages/boxy build directly on it
While I've used Flutter since Alpha, I've been away for a few years. A few things have shocked me in these release notes: how come Impeller still wasn't the default engine for all platforms? Also, why are they migrating to WASM if one of the core features of Dart is compiling to JavaScript? Finally, how come multi window support only get viable now, after four years having desktop support?
Honestly, Flutter is an extremely enjoyable development experience I would recommend anyone I care for to stay away from. The fact it's developed by Google doesn't help: it's a matter of time before they kill it like they did with so many UI libraries and frameworks already, specially with JetBrains developing Compose Multiplatform and the Android team going all-in in the Compose strategy.
> how come Impeller still wasn't the default engine for all platforms
Because Impeller has had quite a bumpy ride. Even as recently as June I reported a bug/regression with basic stuff (lines with partial transparency on desktop). All my Android apps are still built with --no-enable-impeller because I've had many instances where the app just shows a blank screen due to driver conflicts.
It may be getting close to stable now, but it wasn't a smooth transition at all.
Flutter operates more like a 2D game engine. It renders its own views, which involves a lot of arithmetic operations, making WASM a more efficient option than JS.
WASM or JS doesn’t matter. The reason is Canvas instead of DOM. Flutter apps render to the canvas element, because this is the only option for the 2D game engine you mentioned.
Unless it is a trivial app, it would still require quite some effort to port (and test), which has a cost. What do you gain by using Flutter that compensates for that risk?
We've been hearing that Flutter is going to be killed any day now for almost a decade. And yet here we are, it's a stable platform that's quietly chugging along with massive 3rd party buy in. Honestly, Google could abandon it at this point and it would have enough momentum to keep going just fine. Where is Compose Multiplatform? Does anyone actually use that, is it even stable yet?
I still prefer React Native with Expo over Flutter, mostly for practical reasons:
* Language and hiring: TypeScript has a much larger developer pool. Dart is a solid language, but finding experienced Flutter engineers is harder.
* Platform model: React Native maps much more naturally to native platform concepts. Flutter owns much more of the rendering stack, which is powerful, but also creates another abstraction layer between the app and the platform.
* Performance: Flutter can absolutely be fast, so I would not claim otherwise. My experience, however, is that RN has required less work to get interactions and animations that feel consistently native.
* Ecosystem: RN benefits from the broader React, TypeScript, JavaScript, and native ecosystems. Expo has also improved dramatically and now covers a large part of the usual mobile platform work.
* Platform-specific features: neither framework completely eliminates native code. Things like widgets, Live Activities, Dynamic Island, extensions, NFC, and other platform APIs eventually bring you back to Swift/Kotlin anyway.
* Migration to native: if the long-term destination is Swift and Kotlin, I find RN a better intermediate representation. Its component model and platform integration are closer to native concepts, which also makes the codebase easier for agents to translate incrementally into proper native applications.
That said, these are trade-offs, not claims that Flutter is bad. Flutter has improved a lot, and for teams that want a highly consistent cross-platform UI, its rendering model can be an advantage.
You should try Dart/Flutter again, they've improved a lot.
- Dart. It's richer than JS/TS with stronger type safety, and seems purpose-built for UI. Fewer Dart developers than JS, but I'd argue those JS developers cannot be immediately effective coding React Native (Expo) anyway.
- Emulated components vs. real native components. For multi-platform apps, this is actually desirable. These kinds of apps have their own design system.
- Speed. In my experience, it's negligible, but maybe because I keep using the latest version.
- Ecosystem. Flutter/Dart occasionally introduces "breaking" changes (such as migration to null safety, and recently deprecation of CocoaPods). Community very quick to update their plugins and adapt. Some abandoned plugins were immediately forked to keep being maintained.
- Migrating to native platforms, easier for agents to read an RN project. I'd argue it should be _easier_ to do that with Dart since the language is less "ambiguous" than JS.
However it's not perfect. My complaints:
- Not ideal for web apps with lots of FIRST-time visitors, due to initial download. There are some attempts to solve this, e.g. deferred loading, but I think inherently it's unsolvable since you need to download the whole world (a few MBs) to have the app running on your browser. That's why for this scenario I use SvelteKit. But if you already have a mobile app and want to get a web app "for free", this is a useful feature.
- WebView support is inconsistent across platforms (I'm looking at you, Windows and Linux).
> it's unsolvable since you need to download the whole world (a few MBs) to have the app running on your browser
another reason why the web should move from whole app bundling to content addressed CDNs for library code. you would only need to download one copy for each framework version not every site. and its easy to make it decentralized with IPFS if you want.
They still haven't got native scrolling perfect for iOS. I used a big name app just today and I could instantly tell without looking it up that it was a flutter app, because the scrolling felt non-native.
As someone who used all these frameworks professionally for years, I highly agree. Although, I do not prefer Expo due to it's highly annoying build system and dependency hell, but React Native itself in that case. While I understand Google wants a horse in this race, Flutter doesn't feel like a horse to bet on.
- Dart is a really _ugly_ language with lots of tiny annoyances. Its as if someone took worst parts of Java and Javascript and turned them into a language. Terrible to write, terrible to read, terrible to use.
- While there is no Skia anymore, the whole custom rendering of Flutter often caused more trouble than not, from the UI implementation itself all the way to specific low-end chipsets not being supported.
- Ecosystem propagates these insane architectures that don't make much sense and are made to either print apps as fast as possible or to emulate some Clean Code like behavior.
- Web still feels terrible to use, even after all these years.
Since I'm not happy with any of these, I've even taken upon writing a framework of my own that renders into native UI and works with any language (gonna shill it here https://hypen.space). It was inspired directly by years of working with mobile and experiencing the pains of crossplatform development such as Flutter and Expo. We can do better than these!
> Dart is a really _ugly_ language with lots of tiny annoyances. Its as if someone took worst parts of Java and Javascript and turned them into a language. Terrible to write, terrible to read, terrible to use.
While I’m a bit ambivalent towards Flutter, I totally disagree with you on Dart. To me it’s a better version of Java/Typescript with a very mature cross-platform and JIT/AOT compiler. Admittedly there are some things I wish they would take from TS (like discriminated unions), and I haven’t tried “modern” Java either so maybe that’s improved, but even so, I rarely feel like Dart is getting in the way.
I’ve been keeping an eye on hypen.space and hope it succeeds. What is the level of maturity now and are there any multiplatform app examples that are not trivial?
While all of the points you brought up are valid, I've hated every react native app I've ever had to work on.
Not because of react native itself, but because they usually take random react developers to work on these apps and the structure they create is absolutely horrible to work with (compared to, for example, native apps).
What was your experience on that aspect with Flutter?
I agree. RN has historically attracted a lot of web developers who treat mobile like a React website, and the result can be terrible. But I've seen exactly the same architectural problem in Flutter: huge widgets, mixed responsibilities, state everywhere, and very little separation of concerns. The framework doesn't protect you from bad engineering.
Ah, that's a shame to hear. I would only like to add that at least for Android apps that I've been "hanging around" (my team never really worked on them), the teaching materials that are provided have generally made them a lot more pleasant compared to the RN stuff.
I was forced to migrate from pure native development to React Native and Redux is one of the stupidest things I ever witnessed. Or at least the way the previous devs setup that thing, because it’s so easy to make costly mistakes with it.
I lost so many days of my life profiling and debugging to figure out why hundreds of components were re-rendering when a tiny thing changed somewhere completely unrelated
Since when does React Native use real native components? Last time I've checked it wasn't capable of doing ANYTHING with my phones NFC scanner or native camera...
With flutter I can just build a Kotlin component and integrate it easily into my app.
Also Flutters performance is extremely good, I dont know what you are on about. Our app is used on extremely old phones and has great performance. (I am not even a professional android/flutter dev, so I didnt optimize for performance).
You're mixing UI components with platform APIs. React Native does use native platform-backed views. NFC and camera access are separate concerns. If an API isn't exposed, you can write the native Swift/Kotlin module and bridge it, just like you would integrate native code into Flutter. Camera support also already exists in Expo.
I just moved out last month, it's just pain after sometime now, it's okay and good for mobile cross, when it comes to desktop, I'd have to struggle to support linux with quick hangs
Flutter: if you want a pixel perfect version of your app that looks similar on Android and iOS. Some quite popular apps use it and make a shit ton of money, for example Headspace. More here: https://flutterhunt.com/
React Native: totally viable, because core business logic is the same. If you want native UI elements and all the iOS Liquid Glass stuff, but don’t want to have to completely separate code based, React Native is a viable option if you don’t mind installing lots of third party packages for functionality you get out of the box in Flutter or true native apps.
Native mobile: I have one smaller app with quite a custom calendar view, written with Claude Code natively for Android and iOS. Coding agents help and you get maximum control. Mentally, it’s a bit cumbersome to direct you agent to do everything twice. While one platform can serve as a reference implementation for the other, it’s kinda annoying mentally "to do the same feature all over again and test and direct the agent". But it’s doable.
KMP: No experience, I just hate most things around Android.
PWA: That ship has sailed. Nobody knows about PWAs, most PWAs are bad. It’s a bummer really.
Capacitor: make an SPA (offline-first preferably), and use native code plugins via Capacitor. Still quite feasible, comparable to Flutter in the sense that you need to build a custom UI or use a fake version of Liquid Glass and Material. I use Ionic for that, but it’s a bit dated (still on Material v2). Heavily depends on your skills as a web dev to get good UX.
Native was always the best. It was just time consuming, requiring a bigger team. Now with AI helping out, it's probably the best option by far. I still like Flutter a lot though because you can get stuff done fairly quickly and even apply Material design to the iOS apps or vice versa if you want to (if it's a business app where the design doesn't matter too much). Or if you e.g. target win32
Even with AI, maintaining feature parity between Android, iOS, Windows, Linux, and Mac is extremely complex. Flutter makes it so much easier. If I were doing native, I'd probably have to drop all desktop platforms.
In most cases yes but if you don’t want native elements and you want your app to look exactly the same on android as on iOS then flutter is a better choice. Assuming you don’t have any performance limitiations.
I use Ableton, Figma, and Emacs regularly. I have a decade (or more) of muscle memory around these apps. If they suddenly decided to adopt the look, feel, and conventions of their underlying host platform, I’d be very upset.
If I’m using Emacs, I don’t want to use Cmd+S to save my files on macOS and Ctrl+S on Windows. I’ve already memorized C-x C-s. I don’t want Ableton to adopt whatever new design language Apple or Microsoft is chasing this week. I want to open the app and find the UI controls looking and behaving exactly the same as they’ve looked and behaved since I started using it in 2014. I want to write code, make music, do design. I don’t want to be frustrated because the button for enabling the metronome is 15px to the left on Windows vs. macOS.
Apps that look and feel native only make sense in two cases:
1. The app is tied to the platform. E.g. Logic Pro. It can integrate deeply into macOS and use the native widget set because it will never run on any other platform. Same for Bear, Things, Pixelmator, Omni Group apps, etc.
2. The app is a replaceable, throw-away utility. I call these “fungible apps”. For example, it doesn’t really matter which Mastodon or Bluesky client you use. There are hundreds of them, and they’re not complex enough that the loss of familiarity or muscle memory matters very much. You can use one client on Windows, a different one on macOS, and a third one on Linux, and it’ll be fine. They can all be native to their platforms, or not. The interaction model is simple enough that you can afford to have a different one on every platform.
For apps that really matter—the apps I use to put food on the table—I absolutely want them to look and feel exactly the same on every platform. The app is the OS, the actual OS is just a hardware abstraction layer.
Can Flutter be used to build apps like Figma or Ableton or Emacs? I actually don’t think so. It’s a poor toolkit for building anything that must last for more than 3-5 years. If you care about longevity, there are basically only three options in 2026: Qt, Electron, or roll your own like Zed/Sublime.
I don't think you'd want to in most cases, but adapting to different platforms takes energy and thought. For business CRUD apps you may just want to ignore that and get something out that works well.
I've built apps with millions of users using flutter. Quicker, faster and easier for building cross-platform apps if you know what you are doing.
This is coming from a native framework evangelist for many years, and then just tried flutter early days (which was far more difficult than how easy it is today). Now I write almost all my projects in flutter/dart where I can, especially with AI the speed from idea to production is insane.
I’ve been a React Native developer for 8 years, I’ve written many apps with it professionally and personally. Until recently, I would have recommended it wholeheartedly.
This weekend I had an idea I set out to experiment with: if I have an existing React Native app, how much effort would it take an LLM to rewrite it into genuinely native apps. My idea being I no longer need to write cross-platform code and pay the intermediary framework costs, I’d get direct access to the underlying platform. Instead, I could just spec the features I need in the app and the LLM can build it.
It took me a year to build the original app to production quality by hand. My “twins”, as they’ve become known, were at 80% completion in three days of on-off work.
I’m pretty much convinced my experiment was a success. Which sorta terrifies me that I’ve specialised in a technology that can be, for all intents and purposes, be entirely erased.
The only caveat I can find is it is still a great technology for doing cross-platform mobile and web. Using something like Tamagui (as rough as that can be sometimes) allows genuine code sharing across all platforms.
Sucks most that I’m now actively looking for a new React Native role.
I really believe this is the way forward, native platform UI built by AI.
I'm trying it now with an app and so far it's working really well. I build what I can cross platform, the non-ui stuff, then have AI build the UI for each platform.
It even implemented native low-level graphics on each platform: metal, vulkan, and d3d12. It builds SwiftUI on Apple platforms, WinUI3 on Windows, GTK4 on Linux, Compose on Android. The cross platform stuff is Zig with a C ABI.
And yeah, it's a bit terrifying how fast you can iterate. I've built for all these platforms in about a month. It would have taken at least a year, maybe more before. I haven't even optimized the process by having AI agents follow my lead automatically, so as I finish features on the primary platform they could start building the others by watching. Requires some setup I haven't tackled yet (VMs for all platforms with agents waiting).
Be careful, I’ve been using AI to translate my Swift code to Kotlin and sometimes it makes some mistakes that are invisible to you, because the languages are so similar, but it will bite you in the ass eventually, because there are subtle changes between the platforms
Not saying that LLM development isn't fast, but doing a re-implementation of something you know in-and-out is almost always going to be faster, as you skip the probably most time intensive step of product research and requirement engineering.
Absolutely, but that doesn’t discount that it’s now feasible to spec a feature once and have it built for me on both apps. I’m doing the same process on a new project I’m working on and it’s built both apps simultaneously as I’d hoped.
Every time we tried it, it resulted in a worse experience than we knew could be done using native stacks. It is like using sand as a foundation for your house. Random version updates break random things. As soon as you need something a bit advanced on the platform, you are stuck with some barely supported library. Easy to start, hard to maintain and hard to ship a solid product.
Yes, hopefully now that this decoupling is complete, they'll actually start being updated again. The progress was a bit stalled while this process was ongoing.
great for mobile apps, fine for desktops, basically unusable for browsers unless you do wasm, if web can be revamped/improved it can be the best option for cross platform GUI
I treat nesting as a feature: if the nesting starts getting deep, that's the code indicating to extract a child widget. It pushes me toward better composition and smaller, reusable components instead of giant monolithic views.
While you aren't wrong, in my experience when the amount of nesting starts giving me bad vibes it usually indicates that something can be refactored out as a standalone widget.
Still, Flutter now feels ancient to use compared to something like Compose, in that regard.
While the server side is still growing and obviously not as huge as Java etc., Dart definitely is being used on the backend. For instance, https://pub.dev/ itself is written in Dart: https://github.com/dart-lang/pub-dev . :)
The language, like any other, does have some weaker parts, but in general is _very_ nice to write in - thanks to both the language itself and the toolchain built around it.
The apps compile to native binaries for production and are run in Dart VM during development. The SDK is multi purpose. You can write "scripts", you can write CLI apps, servers and with Flutter - the rest of them.
I have user Dart for small personal projects and it's a great language. Somewhat similar to Kotlin, but IMO a bit nicer. Unfortunately the ecosystem is not as developed outside of Flutter as with more popular languages, but it very much exists and pretty nice to use.
I've been using Dart and Flutter for years, but I've never ever met anyone who's seriously using Dart for backend. That would be a very niche thing and not popular with teams.
Of all the myriad projects from Google, how is Flutter/Dart the one that survived the axe? I’m not saying I hate them - I think they’re both really neat - I just don’t understand why Google keeps these limping along with weak support and no clear vision within their broader web ecosystem.
Easy, there are a few google teams that use flutter and the cost savings from not having to have dedicated ios and android teams is very easy to point at to justify the project's existence.
I think Dart and Flutter are very overlooked. The language has completely changed since its release, its statically typed, has null safety, enums, and pattern matching, and is very simple and easy to read. It has fast compilation and a ui framework with hot reload. It's as fast as Js on v8 while using less memory and has the overlooked feature of having very fast, almost 0 overhead, ffi.
I think the importance of good ffi is underrated for these ui languages. For reference, everyone that's using electron has to run two node processes doing ipc over a websocket connection. That's going to waste an absurd number of cpu cycles and memory when you are passing messages around when your app is basically a ui for a cli.
But they also fund JetBrains, Jetpack Compose, and KMP. It feels like the company threw their support behind Kotlin a long while ago on mobile, but internal struggles keep the others limping along. Compose UI tooling no longer requires viewing on device.
You're thinking of Google as a single top down company. It isn't. Think of it as an anarchy of warlords where each pulls the strings and management doesn't really know what's going on.
Flutter made a lot of sense during the Oracle lawsuit when Google needed a way to show Oracle that it can pivot from Java. Now it no longer makes sense but the inertia is too deep.
My guess is that flutter is sold internally through the Huawei support as a leg within China.
How are they limping? Flutter has completely replaced it's rendering engine across all platforms and they're building out major window management support on desktop platforms.
At some point there's just not much exciting new stuff to add. Flutter is a nice stable platform, I'd highly recommend it.
> Flutter has completely replaced it's rendering engine across all platforms
And that new rendering engine is also why apps like Immich are unable to show HDR photos. Apple & Google both pushed broad support for that a couple years ago, with things like Ultra HDR and subsequently ISO 21496-1.
Of course they need to prioritize where to spend resources, like any project, but Flutter also doesn't seem to be on any critical path for fancy headlining new features, either.
I've made a huge critic towards Flutter in another comment of mine, but adoption isn't it: the biggest bank in Brazil, with 135 million clients, is a digital bank whose sole interface is their Flutter app. They are different regarding tech choices (they use Clojure on the backend too), but I think it's a huge testament of how far along Flutter adoption has come.
I really don't understand how/why people deny reality so hard when it comes to Flutter. Reminds me a bit of years ago when people were still scoffing at the idea of anyone actually adopting JavaScript to write web servers with while Node.js was very obviously eating up the market.
It eats the market indeed, and also presents business opportunities for folks like myself, jumping in writing C++ addons, or completely replacing it with Java, .NET, Go, Rust,....
Is that true though? I'm reading HN on an app built using Flutter. I had no idea until recently, so I would assume more apps could use it without my knowledge.
I understand it's limitations vs native apps, but there's quite a few cases where it really doesn't matter.
The biggest one for me is always the fear it will be abandoned. Pretty much goes for any cross platform app framework though.
I used to work at ByteDance and they alone employed I think more than 800 Flutter Devs. Douyin uses Flutter (the Chinese version of TikTok), Grab and Ebay use it, Alibaba and Baidu did too. Toyota and Volkswagen I think both use Flutter. Nubank I think is also a flutter app and they alone have like one hundred million some users.
With the popularity in the Chinese ecosystem alone there's gotta be a billion plus people using flutter.
Most Google's projects that users loved were axed for a reason, typically internal management wars for promotions. Like YouTube really wanted to kill belowed Google Music, so they did. Or Google Pay vs Google Wallet.
Killing Flutter would not promote a manager. For now, of course.
Sure, Adwords migrated from GWT to Dart. (And eventually I followed.) At one point, Dart moved from the Chrome division to the Adwords division. And Adwords alone can fund a team to do developer tools for them. Then, Flutter came a bit later.
It's been over a decade since then, though, and I'm out of touch now.
They still maintaining it's predecessor that the Google "core properties" ran on: Closure (not Clojure), the javascript compiler. It's an evolution of the hack that Gmail initially was built on.
I use Flet in a few projects. It's still somewhat young and the declarative move caused a few issues (for me, mainly because I wasn't familiar with the pattern), but generally I'd say it's stable, feature-complete and the maintainer seems to be in it for the long haul. Also it fills a critical gap that nothing else does, binding a decent UI framework and cross-platform capability to a language with an extremely large and diverse ecosystem; that's what I think will really make it endure.
I always find it strange that flutter isn’t built with golang or typescript. Why use a new language? When flutter came out both languages existed so curious about that.
The main reason i can think of is generics not existing initially
Dart shipped in 2011, four years before Flutter started.
On the technical side, Flutter needed AOT compilation to native ARM for release builds and a JIT for development (that's what makes stateful hot reload possible). Dart does both from one codebase. TypeScript means shipping a JS VM, which is precisely the overhead Flutter was designed to avoid. (In contrast to RN). Dart's other big win is GC tuned for allocating and throwing away tons of short-lived objects which is what happens when you hot reload over and over.
Go has no JIT, so no hot reload, and no generics until 2022, Flutter has a big widget library so that would not have been possible.
And of course the Dart team was inside Google, and had just lost its original mission when Chrome declined to ship the Dart VM, and was willing to change the language to suit Flutter.
I'm not sure why you're being downvoted, it's a super reasonable question.
Iirc the reason is that the Dart team was willing to heavily modify the language and runtime to accommodate the needs of Flutter and the V8 team wasn't.
Does anyone know if the original promise of their simple layout model proved itself?
IIRC, the Flutter team mentioned how using just width/height constraints is enough to represent all relevant layouts. This sounds very nice, being so much simpler than Flexbox and miles ahead of CSS Grid ergonomics.

> how come Impeller still wasn't the default engine for all platforms
Because Impeller has had quite a bumpy ride. Even as recently as June I reported a bug/regression with basic stuff (lines with partial transparency on desktop). All my Android apps are still built with --no-enable-impeller because I've had many instances where the app just shows a blank screen due to driver conflicts.
It may be getting close to stable now, but it wasn't a smooth transition at all.

I suppose AI would help for porting your app if you need to? It's not like the old days.
Unless it is a trivial app, it would still require quite some effort to port (and test), which has a cost. What do you gain by using Flutter that compensates for that risk?
Working on all devices with minimal effort. That's what I use it for anyway, anything else like a sound null safe language with Dart are just a bonus.
This blogpost could've been an mcp doc. Who needs to know about this stuff these days? AI will never pick flutter for a project anyway
We've been hearing that Flutter is going to be killed any day now for almost a decade. And yet here we are, it's a stable platform that's quietly chugging along with massive 3rd party buy in.

I still prefer React Native with Expo over Flutter, mostly for practical reasons:

another reason why the web should move from whole app bundling to content addressed CDNs for library code. you would only need to download one copy for each framework version not every site. and its easy to make it decentralized with IPFS if you want.
They still haven't got native scrolling perfect for iOS. I used a big name app just today and I could instantly tell without looking it up that it was a flutter app, because the scrolling felt non-native.
Scrolling is like an Achilles' heel of Flutter. There's still no smooth scrolling with mouse for web.
As someone who used all these frameworks professionally for years, I highly agree. Although, I do not prefer Expo due to it's highly annoying build system and dependency hell, but React Native itself in that case. While I understand Google wants a horse in this race, Flutter doesn't feel like a horse to bet on.
- Dart is a really _ugly_ language with lots of tiny annoyances. Its as if someone took worst parts of Java and Javascript and turned them into a language. Terrible to write, terrible to read, terrible to use.
- While there is no Skia anymore, the whole custom rendering of Flutter often caused more trouble than not, from the UI implementation itself all the way to specific low-end chipsets not being supported.
- Ecosystem propagates these insane architectures that don't make much sense and are made to either print apps as fast as possible or to emulate some Clean Code like behavior.
- Web still feels terrible to use, even after all these years.
Since I'm not happy with any of these, I've even taken upon writing a framework of my own that renders into native UI and works with any language (gonna shill it here https://hypen.space). It was inspired directly by years of working with mobile and experiencing the pains of crossplatform development such as Flutter and Expo. We can do better than these!

While I’m a bit ambivalent towards Flutter, I totally disagree with you on Dart. To me it’s a better version of Java/Typescript with a very mature cross-platform and JIT/AOT compiler. Admittedly there are some things I wish they would take from TS (like discriminated unions), and I haven’t tried “modern” Java either so maybe that’s improved, but even so, I rarely feel like Dart is getting in the way.
I’ve been keeping an eye on hypen.space and hope it succeeds. What is the level of maturity now and are there any multiplatform app examples that are not trivial?
hypen looks very similar to SlintUI, isn't it?
Funny to see speed in there, my experience is the opposite.
Im a very happy Flutter dev and it's always been odd to see so much negative sentiment around it when there are public discussions.
While all of the points you brought up are valid, I've hated every react native app I've ever had to work on. Not because of react native itself, but because they usually take random react developers to work on these apps and the structure they create is absolutely horrible to work with (compared to, for example, native apps).
What was your experience on that aspect with Flutter?
I agree. RN has historically attracted a lot of web developers who treat mobile like a React website, and the result can be terrible. But I've seen exactly the same architectural problem in Flutter: huge widgets, mixed responsibilities, state everywhere, and very little separation of concerns. The framework doesn't protect you from bad engineering.
Ah, that's a shame to hear. I would only like to add that at least for Android apps that I've been "hanging around" (my team never really worked on them), the teaching materials that are provided have generally made them a lot more pleasant compared to the RN stuff.
I was forced to migrate from pure native development to React Native and Redux is one of the stupidest things I ever witnessed. Or at least the way the previous devs setup that thing, because it’s so easy to make costly mistakes with it.
I lost so many days of my life profiling and debugging to figure out why hundreds of components were re-rendering when a tiny thing changed somewhere completely unrelated
Redux is great and it solves exactly that problem.
You create a selector. You use the selector in a React component.
The component re-renders when the selector outputs a different value, with the usual reference equality caveat.
Does it get any simpler than that?
However, yes, I have seen most developers use Redux incompetently.
They would use actions like "setOrder" instead of "itemAdded", defeating the purpose of a state machine from the start.
> figure out why hundreds of components were re-rendering when a tiny thing changed somewhere completely unrelated
Could you explain how this comes from React Native and/or redux?
I have used Angular with redux (ngrx) and redux made it quite obvious what changed what and why
Out of curiosity, do you have any experience with Kotlin Multiplatform and Compose Multiplatform? I would like to know how that compares.
>real native components
Since when does React Native use real native components? Last time I've checked it wasn't capable of doing ANYTHING with my phones NFC scanner or native camera...
With flutter I can just build a Kotlin component and integrate it easily into my app. Also Flutters performance is extremely good, I dont know what you are on about. Our app is used on extremely old phones and has great performance. (I am not even a professional android/flutter dev, so I didnt optimize for performance).
You're mixing UI components with platform APIs. React Native does use native platform-backed views. NFC and camera access are separate concerns. If an API isn't exposed, you can write the native Swift/Kotlin module and bridge it, just like you would integrate native code into Flutter. Camera support also already exists in Expo.
I see, thanks for clarifying!
I just moved out last month, it's just pain after sometime now, it's okay and good for mobile cross, when it comes to desktop, I'd have to struggle to support linux with quick hangs
Are Flutter and React Native still viable choices today?
I get the impression that more are going for native mobile, KMP or PWA.
Flutter: if you want a pixel perfect version of your app that looks similar on Android and iOS. Some quite popular apps use it and make a shit ton of money, for example Headspace. More here: https://flutterhunt.com/
React Native: totally viable, because core business logic is the same. If you want native UI elements and all the iOS Liquid Glass stuff, but don’t want to have to completely separate code based, React Native is a viable option if you don’t mind installing lots of third party packages for functionality you get out of the box in Flutter or true native apps.
Native mobile: I have one smaller app with quite a custom calendar view, written with Claude Code natively for Android and iOS. Coding agents help and you get maximum control. Mentally, it’s a bit cumbersome to direct you agent to do everything twice. While one platform can serve as a reference implementation for the other, it’s kinda annoying mentally "to do the same feature all over again and test and direct the agent". But it’s doable.
KMP: No experience, I just hate most things around Android.
PWA: That ship has sailed. Nobody knows about PWAs, most PWAs are bad. It’s a bummer really.
Capacitor: make an SPA (offline-first preferably), and use native code plugins via Capacitor. Still quite feasible, comparable to Flutter in the sense that you need to build a custom UI or use a fake version of Liquid Glass and Material. I use Ionic for that, but it’s a bit dated (still on Material v2). Heavily depends on your skills as a web dev to get good UX.
Native was always the best. It was just time consuming, requiring a bigger team. Now with AI helping out, it's probably the best option by far. I still like Flutter a lot though because you can get stuff done fairly quickly and even apply Material design to the iOS apps or vice versa if you want to (if it's a business app where the design doesn't matter too much). Or if you e.g. target win32
Even with AI, maintaining feature parity between Android, iOS, Windows, Linux, and Mac is extremely complex. Flutter makes it so much easier. If I were doing native, I'd probably have to drop all desktop platforms.
In most cases yes but if you don’t want native elements and you want your app to look exactly the same on android as on iOS then flutter is a better choice. Assuming you don’t have any performance limitiations.
Why would you want apps on different os look exactly the same?
Why would you not?
I use Ableton, Figma, and Emacs regularly. I have a decade (or more) of muscle memory around these apps. If they suddenly decided to adopt the look, feel, and conventions of their underlying host platform, I’d be very upset.
If I’m using Emacs, I don’t want to use Cmd+S to save my files on macOS and Ctrl+S on Windows. I’ve already memorized C-x C-s. I don’t want Ableton to adopt whatever new design language Apple or Microsoft is chasing this week. I want to open the app and find the UI controls looking and behaving exactly the same as they’ve looked and behaved since I started using it in 2014. I want to write code, make music, do design. I don’t want to be frustrated because the button for enabling the metronome is 15px to the left on Windows vs. macOS.
Apps that look and feel native only make sense in two cases:
1. The app is tied to the platform. E.g. Logic Pro. It can integrate deeply into macOS and use the native widget set because it will never run on any other platform. Same for Bear, Things, Pixelmator, Omni Group apps, etc.
2. The app is a replaceable, throw-away utility. I call these “fungible apps”. For example, it doesn’t really matter which Mastodon or Bluesky client you use. There are hundreds of them, and they’re not complex enough that the loss of familiarity or muscle memory matters very much. You can use one client on Windows, a different one on macOS, and a third one on Linux, and it’ll be fine. They can all be native to their platforms, or not. The interaction model is simple enough that you can afford to have a different one on every platform.
For apps that really matter—the apps I use to put food on the table—I absolutely want them to look and feel exactly the same on every platform. The app is the OS, the actual OS is just a hardware abstraction layer.
Can Flutter be used to build apps like Figma or Ableton or Emacs? I actually don’t think so. It’s a poor toolkit for building anything that must last for more than 3-5 years. If you care about longevity, there are basically only three options in 2026: Qt, Electron, or roll your own like Zed/Sublime.
I don't think you'd want to in most cases, but adapting to different platforms takes energy and thought. For business CRUD apps you may just want to ignore that and get something out that works well.
I've built apps with millions of users using flutter. Quicker, faster and easier for building cross-platform apps if you know what you are doing.
This is coming from a native framework evangelist for many years, and then just tried flutter early days (which was far more difficult than how easy it is today). Now I write almost all my projects in flutter/dart where I can, especially with AI the speed from idea to production is insane.
We use flutter at work. When you need to target various platforms for the same code base it's extremely competent.
I’ve been a React Native developer for 8 years, I’ve written many apps with it professionally and personally. Until recently, I would have recommended it wholeheartedly.
This weekend I had an idea I set out to experiment with: if I have an existing React Native app, how much effort would it take an LLM to rewrite it into genuinely native apps. My idea being I no longer need to write cross-platform code and pay the intermediary framework costs, I’d get direct access to the underlying platform. Instead, I could just spec the features I need in the app and the LLM can build it.
It took me a year to build the original app to production quality by hand. My “twins”, as they’ve become known, were at 80% completion in three days of on-off work.
I’m pretty much convinced my experiment was a success. Which sorta terrifies me that I’ve specialised in a technology that can be, for all intents and purposes, be entirely erased.
The only caveat I can find is it is still a great technology for doing cross-platform mobile and web. Using something like Tamagui (as rough as that can be sometimes) allows genuine code sharing across all platforms.
Sucks most that I’m now actively looking for a new React Native role.
I really believe this is the way forward, native platform UI built by AI.
I'm trying it now with an app and so far it's working really well. I build what I can cross platform, the non-ui stuff, then have AI build the UI for each platform.
It even implemented native low-level graphics on each platform: metal, vulkan, and d3d12. It builds SwiftUI on Apple platforms, WinUI3 on Windows, GTK4 on Linux, Compose on Android. The cross platform stuff is Zig with a C ABI.
And yeah, it's a bit terrifying how fast you can iterate. I've built for all these platforms in about a month. It would have taken at least a year, maybe more before. I haven't even optimized the process by having AI agents follow my lead automatically, so as I finish features on the primary platform they could start building the others by watching. Requires some setup I haven't tackled yet (VMs for all platforms with agents waiting).
Be careful, I’ve been using AI to translate my Swift code to Kotlin and sometimes it makes some mistakes that are invisible to you, because the languages are so similar, but it will bite you in the ass eventually, because there are subtle changes between the platforms
Do you have an example? I don't doubt it, I just want to make sure I watch out for it.
One downside for sure is lack of deep knowledge on all these platforms can make it difficult to see issues.
Not saying that LLM development isn't fast, but doing a re-implementation of something you know in-and-out is almost always going to be faster, as you skip the probably most time intensive step of product research and requirement engineering.
Absolutely, but that doesn’t discount that it’s now feasible to spec a feature once and have it built for me on both apps. I’m doing the same process on a new project I’m working on and it’s built both apps simultaneously as I’d hoped.
Every time we tried it, it resulted in a worse experience than we knew could be done using native stacks. It is like using sand as a foundation for your house. Random version updates break random things. As soon as you need something a bit advanced on the platform, you are stuck with some barely supported library. Easy to start, hard to maintain and hard to ship a solid product.
Oh finally multi-window support - I might finally be able to flutter for a simple desktop app side project I've been wanting to build.
Flutter is good on its own but dev tooling and long compile times kills all the enjoyment.
Tested lots of flutter desktop apps on Github last year. All have sluggish animation. FPS rarely reached 60.
Debug mode?
I do more mobile/web Flutter dev so haven't got experience here but I'm surprised to hear that. Can you name some examples?
> Linux and Windows now support popup windows, allowing you to build native context menus and utility palettes.
How does such a basic feature only get added so late?
flutter started as a mobile framework, and mobiles didn't support multi windows back then
This doesn't help, desktop support was added 5 years ago, so that's longer than the age of flutter before that
Decoupling material and cupertino makes a lot of sense.
Yes, hopefully now that this decoupling is complete, they'll actually start being updated again. The progress was a bit stalled while this process was ongoing.
great for mobile apps, fine for desktops, basically unusable for browsers unless you do wasm, if web can be revamped/improved it can be the best option for cross platform GUI
> basically unusable for browsers unless you do wasm
Relying on WASM means that nobody on Apple platforms who has Lockdown Mode enabled for better security will be able to use it.
I see that as a win
You are in luck then, use jaspr.
no one and absolutely no one pick flutter because they want do traditional web in the first place
its a cross platform framework that you can share component between mobile and other platform and always has been
I’ve used flutter for a couple of toy web apps. One is just a personal tool , another is a small party game.
Now I might vibe code such things using React, but 5 , 6 years ago Flutter got me what I wanted fast.
Firebase integration is absurdly easy. You can make a crud app in about 30 minutes
Yes but its best work with SPA or WASM type of app like games for example
The one thing I hate about flutter is the ui code having an ungodly amount of nested brackets.
I treat nesting as a feature: if the nesting starts getting deep, that's the code indicating to extract a child widget. It pushes me toward better composition and smaller, reusable components instead of giant monolithic views.
While you aren't wrong, in my experience when the amount of nesting starts giving me bad vibes it usually indicates that something can be refactored out as a standalone widget.
Still, Flutter now feels ancient to use compared to something like Compose, in that regard.
For some reason I prefer those to curlies.
Loc goes brrrrrrr. The tokenmaxxing of the 20s
Didn't realize it until now, but you're right.
LOC is dead, long live token usage.
You clearly need more Lispmaxxing
the "Text and selection" demo caught my attention, why flutter render the shortcuts bar itself and not delegate this to the underlaying os?
how's Dart for back end development? is anybody using it to build APIs? the syntax doesn't look too bad
While the server side is still growing and obviously not as huge as Java etc., Dart definitely is being used on the backend. For instance, https://pub.dev/ itself is written in Dart: https://github.com/dart-lang/pub-dev . :)
The language, like any other, does have some weaker parts, but in general is _very_ nice to write in - thanks to both the language itself and the toolchain built around it.
The apps compile to native binaries for production and are run in Dart VM during development. The SDK is multi purpose. You can write "scripts", you can write CLI apps, servers and with Flutter - the rest of them.
I have user Dart for small personal projects and it's a great language. Somewhat similar to Kotlin, but IMO a bit nicer. Unfortunately the ecosystem is not as developed outside of Flutter as with more popular languages, but it very much exists and pretty nice to use.
I've been using Dart and Flutter for years, but I've never ever met anyone who's seriously using Dart for backend. That would be a very niche thing and not popular with teams.
Try out serverpod. Not affiliated with them- it's just a super nice integrated Dart backend:
https://serverpod.dev/
Of all the myriad projects from Google, how is Flutter/Dart the one that survived the axe? I’m not saying I hate them - I think they’re both really neat - I just don’t understand why Google keeps these limping along with weak support and no clear vision within their broader web ecosystem.
Easy, there are a few google teams that use flutter and the cost savings from not having to have dedicated ios and android teams is very easy to point at to justify the project's existence.
I think Dart and Flutter are very overlooked. The language has completely changed since its release, its statically typed, has null safety, enums, and pattern matching, and is very simple and easy to read. It has fast compilation and a ui framework with hot reload. It's as fast as Js on v8 while using less memory and has the overlooked feature of having very fast, almost 0 overhead, ffi.
I think the importance of good ffi is underrated for these ui languages. For reference, everyone that's using electron has to run two node processes doing ipc over a websocket connection. That's going to waste an absurd number of cpu cycles and memory when you are passing messages around when your app is basically a ui for a cli.
But they also fund JetBrains, Jetpack Compose, and KMP. It feels like the company threw their support behind Kotlin a long while ago on mobile, but internal struggles keep the others limping along. Compose UI tooling no longer requires viewing on device.
Only because it was cheaper to migrate Android to Kotlin instead of Dart. JetBrains needs Google more than Google needs JetBrains.
There are several clues that the reasons were more political than monetary, including some former team members like Jake Warton remarks on Dart.
Note that Dart or Flutter are nowhere to be found on Android developer documentation.
Android used to be its own kingdom separate from rest of Google. And maybe still is.
You're thinking of Google as a single top down company. It isn't. Think of it as an anarchy of warlords where each pulls the strings and management doesn't really know what's going on.
Flutter made a lot of sense during the Oracle lawsuit when Google needed a way to show Oracle that it can pivot from Java. Now it no longer makes sense but the inertia is too deep.
My guess is that flutter is sold internally through the Huawei support as a leg within China.
I’ve had good experiences with Flutter too. It’s actually much easier to build a performant macOS app with flutter than with SwiftUI.
> It’s actually much easier to build a performant macOS app with flutter than with SwiftUI.
Got any case studies?
Just my own apps. Getting good performance out of SwiftUI on Mac is quite difficult. Loads of footguns.
And yet I dont see any Flutter macos apps at all.
Curious how you feel about KMP and Kotlin Compose.
I like kotlin a lot but I didn't get to fully test KMP and Kotlin Compose. I chose flutter because I liked dart's wasm story better than kotlins.
How are they limping? Flutter has completely replaced it's rendering engine across all platforms and they're building out major window management support on desktop platforms.
At some point there's just not much exciting new stuff to add. Flutter is a nice stable platform, I'd highly recommend it.
> Flutter has completely replaced it's rendering engine across all platforms
And that new rendering engine is also why apps like Immich are unable to show HDR photos. Apple & Google both pushed broad support for that a couple years ago, with things like Ultra HDR and subsequently ISO 21496-1.
Meanwhile Flutter still doesn't really have wide gamut support https://github.com/flutter/flutter/issues/189155
Of course they need to prioritize where to spend resources, like any project, but Flutter also doesn't seem to be on any critical path for fancy headlining new features, either.
Right, but, nobody uses it. So what's the point for Google?
I've made a huge critic towards Flutter in another comment of mine, but adoption isn't it: the biggest bank in Brazil, with 135 million clients, is a digital bank whose sole interface is their Flutter app. They are different regarding tech choices (they use Clojure on the backend too), but I think it's a huge testament of how far along Flutter adoption has come.
Also, Google dogfoods it quite a bit.
Interesting, so Nubank is a heavy Flutter user?
https://building.nubank.com/scaling-with-flutter/
https://flutter.dev/showcase/nubank
Nubank also uses clojure and adoption is still a big issue.
Third-party analysis (https://appfigures.com/top-sdks/development/all) has Flutter used in 16% of iOS apps and 24% of Android apps (free)
Archive link: https://archive.is/IIUaj
I really don't understand how/why people deny reality so hard when it comes to Flutter. Reminds me a bit of years ago when people were still scoffing at the idea of anyone actually adopting JavaScript to write web servers with while Node.js was very obviously eating up the market.
It eats the market indeed, and also presents business opportunities for folks like myself, jumping in writing C++ addons, or completely replacing it with Java, .NET, Go, Rust,....
Is that true though? I'm reading HN on an app built using Flutter. I had no idea until recently, so I would assume more apps could use it without my knowledge.
I understand it's limitations vs native apps, but there's quite a few cases where it really doesn't matter.
The biggest one for me is always the fear it will be abandoned. Pretty much goes for any cross platform app framework though.
The creator of flutter was on here saying that 1/3 of all apps on the App Store use it. That seems to be a lot more than “nobody”.
The creator of flutter lied then. That's not true.
How do you know? Why are we inclined to believe you over him?
>but, nobody uses it.
I used to work at ByteDance and they alone employed I think more than 800 Flutter Devs. Douyin uses Flutter (the Chinese version of TikTok), Grab and Ebay use it, Alibaba and Baidu did too. Toyota and Volkswagen I think both use Flutter. Nubank I think is also a flutter app and they alone have like one hundred million some users.
With the popularity in the Chinese ecosystem alone there's gotta be a billion plus people using flutter.
Google AdSense uses it.
Been using it for six years with fairly high success: https://stockevents.app
I guess because they have buy-in from within Google? Google Pay, NotebookLM, Family Link, Google One, etc. are made with Flutter.
Most Google's projects that users loved were axed for a reason, typically internal management wars for promotions. Like YouTube really wanted to kill belowed Google Music, so they did. Or Google Pay vs Google Wallet.
Killing Flutter would not promote a manager. For now, of course.
Google internally uses dart, and I remember hearing that adwords in particular was rewritten in dart at least for the frontend relatively recently.
So they're probably investing in it enough for basic maintenance, but don't really care about evolving the language.
Sure, Adwords migrated from GWT to Dart. (And eventually I followed.) At one point, Dart moved from the Chrome division to the Adwords division. And Adwords alone can fund a team to do developer tools for them. Then, Flutter came a bit later.
It's been over a decade since then, though, and I'm out of touch now.
In fact AdWords is the reason Dart was still around when Flutter came to be.
They still maintaining it's predecessor that the Google "core properties" ran on: Closure (not Clojure), the javascript compiler. It's an evolution of the hack that Gmail initially was built on.
In one of their dev surveys, they did float the idea of divesting Flutter.
Flutter's not a web ecosystem project. It doesn't do HTML at all. Using canvas to pump pixels in people's faces does not the web make.
Awesome. I'd love if Flutter could also finally get Impeller on Web (I'm tracking the GitHub issues, seems like there's progress at least).
I personally would like for it to pick up some ideas from Svelte.
Been waiting especially for multi-window so it can be picked up by Flet.
Are you using Flet? If yes do you think it's mature enough and has a potential to stay long "in the game"?
I use Flet in a few projects. It's still somewhat young and the declarative move caused a few issues (for me, mainly because I wasn't familiar with the pattern), but generally I'd say it's stable, feature-complete and the maintainer seems to be in it for the long haul. Also it fills a critical gap that nothing else does, binding a decent UI framework and cross-platform capability to a language with an extremely large and diverse ecosystem; that's what I think will really make it endure.
Thanks. And do you know what it has to do with Flutter these days actually? There is barely any mention of Flutter in the website etc :/
I've never used Kotlin, but I really enjoy Flutter. Not nearly as much as SwiftUI and the Lord's language, mind you.
Flutter can get you up and running quickly. If I want cross-plaform support, one codebase is hard to beat.
> We are actively working toward enabling WebAssembly (Wasm) by default for Flutter web applications, bringing native-like performance to the browser.
lol.
I always find it strange that flutter isn’t built with golang or typescript. Why use a new language? When flutter came out both languages existed so curious about that.
The main reason i can think of is generics not existing initially
Dart shipped in 2011, four years before Flutter started.
On the technical side, Flutter needed AOT compilation to native ARM for release builds and a JIT for development (that's what makes stateful hot reload possible). Dart does both from one codebase. TypeScript means shipping a JS VM, which is precisely the overhead Flutter was designed to avoid. (In contrast to RN). Dart's other big win is GC tuned for allocating and throwing away tons of short-lived objects which is what happens when you hot reload over and over.
Go has no JIT, so no hot reload, and no generics until 2022, Flutter has a big widget library so that would not have been possible.
And of course the Dart team was inside Google, and had just lost its original mission when Chrome declined to ship the Dart VM, and was willing to change the language to suit Flutter.
I'm not sure why you're being downvoted, it's a super reasonable question.
Iirc the reason is that the Dart team was willing to heavily modify the language and runtime to accommodate the needs of Flutter and the V8 team wasn't.
I think this is the video that talks about this: https://m.youtube.com/watch?v=xqGAC5QCYuQ
