Is Flutter worth to learn if you are a freelancer?
Hello!I just started my freelance path (so far I have made only 2 orders as Web dev with Svelte JS framework). In Web dev, it has always been a challenge for me to design and style css, so it always takes a lot of time / effort / nerves.Yesterday I stumbled upon Flutter, saw a couple of videos on youtube and thought "damn, it's very easy to make a more or less normal looking UI with that Widget stuff ..." and the thought came to jump on this "hype-Flutter-train". And so, I have a few questions:1) As far as I understand, Flutter allows you to create apps for both Android and IOS, but how much do you need to know a specific platform for production apps? For example, wouldn't it be a problem that I don't know anything about Mobile Development at all (but I will know Dart / Flutter)?2) OOP. As far as I understand, OOP is the dominant way (I haven't seen any other way at all) of creating applications in Flutter. But is it possible to use (successfully use) Functional Programming with dart-packages like functional_widget and dartz ? I have nothing against OOP, just after Svelte I really don't want to see such a huge boilerplate in the form of classes ...3) Regarding freelancing itself, as far as I understand, mobile development is also subdivided as frontend / backend and in order to be a "Full Stack Flutter Developer" you will need to use other programming languages ​​for the backend or "Platform as a service" like firebase ...Is it realistic to do only the frontend part? Because I tried to search on upwork using the keyword "Flutter" and there are only 1 "frontend only" out of 15-20, and for the rest you need "Fullstack" skillset ...

Hi all, It seems that there is no official / core flutter library for playing audio within the framework. Is this correct? If so, what is the usual approach for playing audio? Are there any de facto standards even though no official one is available? I am writing material on this, so I would

A finite state machine for dart.
FMS2 provides an implementation of the core design aspects of the UML state diagrams. FMS2 is derived from the FSM library which in turn was inspired by Tinder StateMachine library. FMS2 allows a user to declare each transition or provide dynamic transitions. FMS2 support Guard Conditions from the UML 2 specification.dart import 'package:fsm2/fsm2.dart'; void main() { final machine = StateMachine.create((g) => g ..initialState(Solid()) ..state<Solid>((b) => b ..on<OnHeat>((s,e) => b.transitionTo(Liquid()) condition: s.temperature + e.deltaDegrees > 0) ..on<OnHeat>((s,e) => b.transitionTo(Boiling()) condition: s.temperature + e.deltaDegrees > 100) ..on<OnMelted>((s, e) => b.transitionTo(Liquid()))) ));Github:https://github.com/bsutton/fsm2Pub.devhttps://pub.dev/packages/fsm2

<b>Flutter with 1 year - lesson learned and still struggling</b>
It's my first full-time programming with my colleague. Previously I just copy and paste javascript sometimes. At this work, the App has been 5k+ loc and 3k commit.Working with Flutter was mostly a fun time. As everyone will feel, the UI implementation was really natural.Bloc pattern (Library is not used) and Provider are used. When using Stream, especially if you don't care about dispose or cancel, it was difficult to fix this because the listener was alive with a memory leak.```dart class SomeBloc implements Disposable {final StreamController ctrl = StreamController();StreamSubscription subs;SomeBloc() { subs = repository.data.listen((x) { if (x > 3) ctrl.sink.add(x); }); }// &#128683;&#9888;&#65039;&#128683;&#9888;&#65039;&#128683;&#9888;&#65039; Alaways do cancel and close. dispose() async { await subs.cancel(); await ctrl.close(); } } ```In particular, after listening, I felt that the async operation is a very dangerous operation. I think a language that directly manages memory should care about resource release in like this.```dart // Stream with async operation is hard to debug &#128557; var subs = someStream.listen.((x) { var url = await getFromFirestorePathToUrl(x); await player.load(url);// if you have to cancel an operation, it is tough to get correct. if (isPlayerPlaying) return; await player.play(); }); ```RxDart was very helpful. In most cases, CombineLatest was used to receive multiple streams and deliver them to the view.```dart // &#10084;&#65039; Rx combineLatest // &#9996;&#65039; Miss js destructuring assignment // const [profile, content, isSelected] = snapshot.dataStreamBuilder<List>( stream: Rx.combineLatest3(profileBloc.profile, repository.content, bloc.isSheSelected, (a, b, c) => [a, b, c]), builder: (context, snapshot) { if (snapshot.hasData && snapshot.isNotEmpty) { Profile profile = snapshot.data[0]; Content content = snapshot.data[1]; bool isSelected = snapshot.data[2]; return Post(profile, content, isSelected); } else { return CircularProgressIndicator(); } } ); ```I want to know it is passable to convert Stream<List<Stream<Object>>> to Stream<List<Object>>. If it can be, please let me know. Perhaps it is about traverse in functional programming.```dart // Is this passable? // traverse:: Stream<List<Stream<Object>>> -> Stream<List<Object>>Stream<List<MetaPost>> metaPosts(String id) => repository.metaPosts; Stream<Post> post(String id) => repository.post;Stream<List<Stream<Post>>> postFromMetaPosts(String id) { return metaPosts(id).map((metas) { return metas.map((meta) { return post(meta.id); }).toList(); }); }Stream<List<post>> postFromMetaPosts2(String id) { // ?? } ```Provider was mostly used for dependency injection, but it was inconvenient to distinguish between context.read and context.watch. I thought it would be nice to have a Provider that is only provided for DI use. Or maybe I should use another library or just use InheritedWidget.``dart // I always set providers ininitStatewithcontext.read` class _SomeStateWidgetState extends State<SomeStateWidget> { Repository _repo; AuthBloc _auth; SomeStateWidgetBloc _bloc;@override void initState() { _repo = context.read<Repository>(); _auth = context.read<AuthBloc>(); _bloc = context.read<SomeStateWidgetBloc>(); super.initState(); } @override Widget build(BuildContext context) { return ListView( children: [ Post(_bloc.isSelected, _auth.currentUserId), // &#128076;safe _chip(), ] ); }Widget _chip() { return Chip( _auth.currentUserId, // &#128076;safe onTap: () async { bool isDeleted = await _repo.isDeleted(); // &#128076;safe print(isDeleted); }) } }// But still hard in stateless widget class SomeStatelessWidget extends StatelessWidget { const SomeStatelessWidget({Key key}) : super(key: key);@override Widget build(BuildContext context) { var _auth = context.watch<AuthBloc>(); // &#128123;watch var _bloc = context.watch<SomeStatelessWidgetBloc>(); //…

Why doesn't flutter adds column/row spacing?
Context: https://github.com/flutter/flutter/issues/16957TLDR;The problem: Flutter rows and columns don't have spacing, hence padding and SizedBox should be used. As mostly they are generated from lists, it requires extra attention for a MUNDANE thing.The argument given by some people is "performance", IMO spacing property can save from doubling the children in a row/column which inserting a SizedBox produces.

Backend pro seeking Flutter pro for symbiotic relationship. Devs helping devs -- *not* a "business opportunity."
Note: I am not looking to start a company or project together.I'm looking for someone for whom Flutter & Dart are second nature, but who would very much like to be able to create their own back-end applications and have already spent enough time & effort learning to start hitting walls.I'm a long-time back-end developer. I've been the tech backbone of a couple of startups, and have created production applications from scratch multiple times.What I've never done well is anything to do with UI. My web pages are ugly but functional. I've never done mobile development.However, I've found Flutter and it's something I can really get into. I'm doing a course and going through books and it's going pretty well. I can see that I'm going to be able to do amazing things.Proposal: When I have a "quick stupid question" that's not submitting to my Google-fu, I can IM or e-mail you (Google Hangouts preferred). When you have a "quick stupid question" about backend/API stuff, you can IM me. That's it. If we became friends along the way, that would be fantastic. But not a requirement.I have over 20 years' experience, mostly back-end and command-line.Things I'm knowledgeable about:GoPythonSQL (PostgreSQL preferred)RedisETLLinuxnginxThings I'm not knowledgeable about or actively avoid:WindowsPHPJavaApacheMySQLI'm also anti-ORM and anti-framework, thanks to having a lot of experience with both.If your interests align with my knowledge, please contact me with your background in Flutter & Dart.Note: If you disagree with my opinions on anything above, awesome. You may even be right. However, I'm not interested in any flame-wars or arguments, so if you want to educate the world please go write a blog post or record a podcast instead of polluting this thread.Thanks!
