Why Flutter's performance is lower than native?
Hi all,I hope it's okay to ask question in here, but i haven't found any restrictions in the "Read this before posting".
Can someone explain to me why Flutter is slower than native Android or IOS? As far as I know Flutter compiles to native executable Code so it should be as fast as native Android, right?​Thanks in advance!

Minimal Counter app with Flutter Hooks, ChangeNotifier and Streams
I came up with a minimal app using a ChangeNotifier model that gets transformed into a Stream to be consumed by a custom Hook to update the widget. Thought I'd share.```dart import 'dart:async';import 'package:flutter/foundation.dart'; import 'package:flutter/widgets.dart'; import 'package:flutter_hooks/flutter_hooks.dart';main() => runApp(MyApp());class MyApp extends HookWidget { @override Widget build(context) { AsyncSnapshot<Post> snapshot = useChangeNotifierAsStream(Post()); return GestureDetector( onDoubleTap: () => snapshot.data.count++, child: Center( child: Text( 'Counter: ${snapshot.data.count}', textDirection: TextDirection.ltr, ), ), ); } }AsyncSnapshot<T> useChangeNotifierAsStream<T extends ChangeNotifier>(T model) { final stream = useMemoized(() => changeNotifierToStream(model)); return useStream(stream, initialData: model); }class Post extends ChangeNotifier { int _count = 0; get count => _count; set count(value) { _count = value; notifyListeners(); } }Stream<T> changeNotifierToStream<T extends ChangeNotifier>(T model) { StreamController<T> _controller;void _listener() => _controller.add(model); void start() => model.addListener(_listener); void end() => model.removeListener(_listener);_controller = StreamController<T>( onListen: start, onPause: end, onResume: start, onCancel: end, ); return _controller.stream; } ```

Dynamic Profile Creation w/ Google Sign In
How would I go about implementing a user profile functionality with google sign in. I have the google sign in functionality completed, but when the user logs in, I want the user to complete a profile (phone number, address, etc.) and have that information saved with their uid in cloud firestore. Any direction would be appreciated!

Any advice on firebase cloud messaging?
Hi,I'm about to integrate firebase cloud messaging into my app and was wondering if redditors had any design advice. All the tutorials I have found place the flutter code into the main.dart file or a home screen.dart file. Is there a good design practice for these notification modules in a production app. Would placing them in a services folder and then importing into main work?Thanks,
