Mutating widget members directly when not controlling how the widget looks
This is not a help request, I know how to solve this problem, but of all the solutions, the one that seems the best is also the one not recommended in the docs and I want to discuss that.First, I want to explain that I understand the difference between stateless widget, and stateful widget and how they are built and function. Specifically I understand that stateful widget consist of an immutable widget on top and a state class below it, and for performance reasons, mutating the state would result in recreation of a new widget with the new state.​While working at my rather complex app with many stateful and stateless widgets, I came a across an interesting situation, I have a column with a list of stateful widgets where I would need to keep some temporary mutable data related to them. changing this particular data doesn't change the appearance of these widgets, additionally I would like to be able to reference that data directly one time at the end with a button press from the parent.So now I have a couple of ways to accomplish this,1) elevate the entire state of all these widgets into the parent widget and pass a complex set of call backs to allow the children to change the state of the parent, but as I mentioned, none of these widget change at all in appearance.2) use a provider/changeNotifier to separate the data from the view, but that is hopping between too many classes and just makes the code very complex.3) simply have the data in a class member in the children widget, letting each widget mutate it according to its own logic, then when I need to collect the data from the whole list of widgets I can simply access them like a regular class, kinda like this

class QuestionView extends StatefulWidget { ... int score = 0; const questionHeader = "some header" ... } // then in the build method of the parent ... List<QuestionView> questions = [...] //then ...Column( children: questions) //then at the end ...onTap : (){ for (var q in questions) { //do something with q.score } } 

I tried the third way and it seems to work just fine without any issues. but it feels "Hacky" and I get a "Widget is supposed to be immutable" warningWhat is the potential problem with this approach and why isn't it recommended. it seems like this would actually be the least expensive way to do this.

Is it a good idea to start coding with Flutter, Dart and Rust?
Hello, Flutter devs!Currently I'm starting out as a UX/UI designer and no code developer for now. My goal is to be able (cross-platform) apps and services on various scales for myself and clients. For example, wikis and e-commerce apps. The gamedev is my another passion but I understand that it takes way more time for that so I want to focus on making great UX/UI apps so I can launch them and to understand coding better while learning — I've heard Dart and Rust are really good languages ahead of their time.I'm inspired a lot by Pieter Levels and his projects, especially Nomad List. So I really want to make such things myself and earn for a living but also progress steadily while learning.Some people might suggest learning C++ but I think it applies more for those who just want to be able to code with no current idea in mind. Myself, I have a goal and understand what I want to be able to do in a close future.Is it a good idea to start with App Brewery's Flutter and Dart course? Should I start learning Rust, if so, what courses for newbies can you recommend?Thank you for your replies in advance!Feel free to ask questions!P.S: Design is a huge passion of mine and I love it. Bad financial situation gave me a push to start designing — I'm working on a Chrome extension design for now (and on my website too). I plan to start looking for clients when I'll finish the extension and website design. I'm working with Figma and Webflow. Afterwards, while looking for clients, I want to make a web app — wiki app for a Crytek game. I plan to make it with Webflow and Bubble. My wish to make it a native app to publish on Google Play and, eventually iOS. That's why I'm inspired to learn to code — it's amazing and gives me more opportunities to do what I want, to make my ideas come to life.

Question: What are the best options for simple animations with synced audio?
Hey guys, we are new to Flutter (have done a fair bit of native Android, some React Native, and some iOS) earlier. We are building an app that has what we can call simple programmatic animations (say, a character talking, a few objects moving around etc; all 2D for now). As far as we can tell, we could either render and manipulate visual assets directly, or use RIVE. We are trying both. One thing that is crucial for our use-case is getting the audio / animation sync right. We've come across some comments and a recent Youtube video complaining about longstanding issues with jank when building for iOS on Flutter. Since we syncing is a must-have for us, wondering if jank or any other latency-inducing issues with animation are a concern. Are there any other alternatives (within Flutter)? Any feedback and pointers would be lovely! Thanks

Using TCP sockets in a Flutter web app
I can create a mobile Flutter app and use TCP sockets in there. What if I "convert" that mobile Flutter App into a Flutter web app? As far as I know, it is not possible to use TCP sockets in JavaScript or a browser. What would happen than? Would it simply not compile?

How is the performance of current Flutter 2.0 for the web?
Hi all! I am currently in the phase of trying to find a "stack" for a pretty decently sized personal project i have. I like to try out new things and even tho i have used Flutter in the past i have never used it for the web, so thought why not use it now.The problem is, this project is intended to be used. Its not just for looks. So i'd like it to work decently. I heard that Flutter web has some problems performance wise compared to JS. Also that its scrolling is absolutely awful. Are those true? Should i just use JS for the time being?

Coming as a iOS Developer
Hello everyone! First time here and I’m coming here with an open mind. I’ve been an iOS developer for many years now and work mostly with Swift. For the longest time, I HATED the idea of cross platform mobile development like React Native. How can one language/framework truly build on both platforms? What if Apple decides to just shut apps off that’s not using native?Flutter has been getting more and more popular. I am intrigued by the language and also the amazing community behind it. What are some pros and cons to Flutter? As someone who exclusively develops in Swift, what are some things I should keep in mind if I end up doing the transition?Thanks!

How can you possibly call flutter web stable?
To be honest, I'm a bit disappointed by the 2.0 announcement. How is it justified to move flutter web to stable ? This feels like pure make belief to me.Since its conception, flutter web has been a bit of a moonshot. Mapping the system of widgets to html is highly non-trivial and can lead to weird compatibility and performance issues. To work around this, the flutter team conceived a canvaskit based renderer, which allows them to control the entire tech stack but brings in a huge range of issues on its own.Flutter web suffers from 3 main issues:They try to reimplement the wheel. Text rendering, scrolling, etc are usually done by the browser. With the canvaskit renderer it's all done by flutter. Which means a crazy amount of work to get it right. The result is an experience that doesn't feel natural. Try scrolling in the flutter gallery. The movement speed and bounce effects are subtly different from other websites.Did I mention scrolling? Flutter on the web suffers from lots of stutters and yanks. This is notoriously bad for scrolling in lists. But the problem can be seen in many places, I just watched the plasma demo on my iPad pro 11 from 2018, it stutters a lot.time to interactive is a nightmare. Since flutter doesn't rely on the browser to do the heavy lifting, they need to pull in huge ressources for their renderer. I challenge you, pick any flutter web app and look at the lighthouse score, it's pretty grim.How come everyone is talking about user experience, but then they don't face these blatant performance issues. There's lots of talks how improving the performance of a web app has increased user retention. But flutter is simply not able to reach any reasonable performance metrics regarding "first meaningful paint" and "time to interactive".Here's a link web.dev/measureGo for it, put some flutter demos in there, like the gallery.After watching the show I don't see an improvement that justifies declaring the web support to be stable. Particularly the canvaskit renderer has been around for quite some time now. Don't get me wrong, I enjoy using flutter on mobile and I'm intrigued by their vision for the web. But bumping the version number to 2 and declaring web support to be stable seems just arbitrary to me.

Can flutter desktop apps be reversed engineered?
When I ask this I am fully aware that anything that is not server side can be reverse engineered, it just boils down to how hard/expensive it is and how committed the hacker is, so with that in mind how easy or hard is it to reverse engineer a flutter desktop app?when building in python, it is very easy to reverse engineer some code and we usually have to use some Cython to compile our sourcecode and make it harder to read, is a desktop flutter app safer?

Stable ≠ Production
We could really use a very high-level roadmap for each platform that the team determines meets their expectation for the platform being marked as production-ready. I realize this is a bit of a fuzzy line since the needs of an enterprise application may differ from a beats maker, but there are some clear lines. Even in the Flutter Engage Q&A the panelists said web is not production ready, but the Flutter announcement says that it is. They also said that Desktop is beta and lacks accessibility support and multi-window.How can Google do a better job of informing us when they think a particular platform meets the reasonable criteria to be called production-ready?

OPINION: Flutter 2.0 was disappointing and not the direction I wanted for Flutter
This is just a personal opinion, and I'd love to hear your views. All my opinions come from me mainly being a Web Dev for 5+ years and a Flutter Dev for only around 1.5 years.When I learnt Flutter, I had only one goal - To make mobile apps rapidly for cross-platform and not have to write too much boilerplate code to get that done. And as Flutter progressed, I really hoped for more in that exact region - improve cross-platform mobile development. While Flutter Web and Desktop are a welcome addition, and I can't speak for Flutter Desktop cause I haven't tried it, Flutter Web has been incredibly disappointing.The world of Web Dev is rapidly progressing. React and Vue are not only hugely supported by most other libraries and SDKs, but they're also highly optimised. I get the appeal of learning one framework and building everything in it, but at the current stage Flutter Web has a long way to go before I call it stable. If I wanted to build a serious, huge project, there's no way I'm choosing Flutter right now. With frameworks like NextJS for SSR and multiple CSS UI Libraries for any JS Framework, I believe native web solutions like React will be superior.Most importantly, the appeal of Flutter was writing one code for anywhere. Android and iOS with the same codebase. There's no way the same codebase works for the Web too, so why bother rewriting your app to suit the web in a framework that's not built for it, just to reuse some components and logic?I've been long hoping for features on Flutter on the mobile side like Homescreen Widgets, More Native Mobile OS support, smoother apps etc.I'm really disappointed to see the direction Flutter is taking, trying to be the jack of all trades before it's really nailed down one properly.I would love to hear your opinions and whether you think Flutter made the right choice pushing Web and Desktop currently
