Project Help - Android Order System for Canteen
Hello everyone, so here's the thing,
I'm going to develop and android/iOS application via flutter and the application is an ordering system for a canteen. First which database should I use, SQLite or Firebase? I need to store item IDs, prices, qty etc. And since I've not found enough tutorials on Firebase and flutter so I'm little confused whether to use it or not and same goes for SQLite as well.Then second thing is, I've seen people making classes in Flutter and I don't know how will I use different classes in my project, Is there anything you can help me with?Thanks a lot <3 To the community who helped me whenever needed <3 <3

Clarification about Redux
Hi, I need some clarification about the Redux design pattern.Consider a "Settings" page with many setting-related widgets such as toggles, sliders, input fields etc. This page uses a StoreConnector and, consequently, a model and a state that save all the values of the user's settings.When one single setting is changed, is the entire widget tree rebuilt as a result?If so, isn't Redux a terrible pattern for optimisation? Or is there something that Redux/Flutter does during this entire process for avoiding unnecessary rebuilds?If switching a single toggle leads to all other toggles, sliders, input fields, etc to rebuild then what is the point of the Redux design pattern?

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!

What is Dart convention for writing Models ?
So coming Java background i would always write instance fields first and then constructor/s.In Dart what I am seeing its other way around, which is confusing sometimes, at first look, but its not always like that.Is there a clear rule to this ? Is it a Dart convention ?
