What is your state management preference
I've been trying out different state management tools for Flutter. For react projects I almost always go for redux, I could even say it's become standard for me and I assume for many people.I'm wondering how this is perceived for Flutter. What is your preference for state management and why? Also if your preference changes depending on context, would be nice to hear about it as well.

The `json_helpers` contains functions that make it easier decoding JSON objects directly from strings, lists and maps.
https://pub.dev/packages/json_helpersAllows you to simplify decoding JSON objects directly from `String`, `List` and `Map` values (eg. from request body).```final list = '[{"name":"test1"},{"name":"test1"}]'.decodeJsonList((e) => Data.fromJson(e));print(list[0].name);​final data1 = '{"name":"test1"}'.decodeJson((e) => Data.fromJson(e));print(data1.name);​final data2 = {'name': 'test1'}.fromJson((e) => Data.fromJson(e));print(data2.name);```

Is there a Flutter State Management tool like Vue's Vuex?
I have worked with Provider and its great. I recently developed a Vue app and used Vuex for State management. It is awesome. I would love to know if there is any Flutter State Management tool like Vue's Vuex?Thanks

What do you think are flutter's biggest drawbacks right now and do you think the flutter team will be able to solve them in the future?
I'm trying to get into mobile development and flutter seems to tick all the boxes. However, as a beginner, there might be drawbacks that I am not aware of right now and therefore want to hear your opinion on the matter.Thanks!

Retrieve Data for a Leader board in flutter apps with firebase
Im breaking my head up with this question. I didn't find a good solution yet getting for example the top 10 rated movies of the day, of the week, of the month in a smart way from my firebase firestore.Does anybody already made experience with such leaderboard data in his app and has a nice approach how to retrieve that data in a nice way? This seems to be really rare if you do some research on that topic.Im very interested in your solutions!

Already tried something like this which isn't good since we have to do a lot sorting on client: 

QuerySnapshot snapshot = await FirebaseFirestore.instance.collection('tasks').where('dateWhenProofed', isGreaterThanOrEqualTo: 1).orderBy('dateWhenProofed', descending: true).limit(10).get(); snapshot.docs.forEach((document) {Data data = Data.fromJson(document.data());_rankingResult.add(data);_rankingResult.sort((a, b) => b.rating.compareTo(a.rating)); });Everything I tried ends up isn't fine yet or ends up in limitations.

Firebase & Flutter how to structure my data and how avoid high costs by checking if a username already exists
currenty when somebody registers in my app, im providing an Input field which returns if the entered username already exists in the database.

Future getUserName(String userNameFieldInput) { print('userNameFieldInput: $userNameFieldInput'); return FirebaseFirestore.instance .collection('usernames') .doc(userNameFieldInput) .get() .then((value) => value.exists ? true : false) .catchError((error) => print(error)); } 

Im returning true or false and thats totally fine. Im not sure if my database structure is fine for that. I would love to have some recommendations on here. Also how many reads do we have here? IM using the Firestore.

Collection: I-- usernames I I- marcel I I- tim I I------ USERID: true I I-- users I I-- USERID I I-- USERID I I-- name: marcel I I-- gender: male I I-- hobbys: snowboarding I

New Flutter Flame Tutorials to Make Mobile Games
Flame is a 2D game framework for Flutter. It is on version 1.0.0-rc8.I've added two new tutorials to my series on FlameIntegrate Flutter Widgets into Flame Mobile Games - shows how easy it is to add Flutter icon buttons to Flame mobile app gamesFlame Audio in Flutter Mobile App Games - flame_audio is a separate package and not included in the base flame packageI also added a "What is Flame and Who is it For" video as an intro to the series.After I received some nice questions, I realized that people might not be familiar with Flame. Here are the basics.Flame is an open source 2D game engine for Flutter.Flame is for people who like Flutter and Dart.There's no real feature advantage using Flame over Unity or Phaser (JavaScript). The only advantage of Flame is that it is the Dart and Flutter workflow.Flame is moving to 1.0 and the documentation and many tutorials may be outdated. If you want to use the pre-release 1.0 Flame framework, these simple tutorials may help you dip your toe into Flame.Performance of Flame is good. Graphics and sprite animation are of the quality you would expect from Flutter apps, which is great IMO.I believe Flame does run on desktop and web in addition to mobile, but I only use Flame on mobileI am building these video tutorials as a hobby as I am sheltering-in-place in California and I enjoy the interaction with people online. Flame is good if you want to learn more about Flutter and Dart.Here are some benefits to learning Flame:As the site documentation is a bit outdated due to the transition to 1.0, you will need to read the source code of the Flame libraries with CTRL-CLICK when you are coding. This is actually a nice way to learn more about constructors which can go pretty deep with Dart.For the same reason as above, you will learn more about mixins and extensions, including ideas on how to write them yourselfif you are new to game development, learning about game development can help you understand and optimize other types of animations in Flutter business apps. This is not a direct connection, but if you understand updates and rendering more deeply, it may give you ideas to improve your business apps and make them more delightful or engaging.The Flame engine and components themselves are great, so if you power-through the sparse documentation problem, then building the app is gratifying because the actual game will be pleasant to use and beautiful.You can also put all those beautiful Flutter widgets into Flame. It feels great to have these pre-built components that just drop in with little effort.Hope everyone is trying to keep motivated and stay positive during COVID health restrictions. It's tough, but let's keep trying our best to improve things.

Flutter 2.0, shout out to the Flutter Team!!!
In my over 3 decades work as a developer I have never upgraded my development environment to a major upgrade in such a short period of time. Outstanding!!!I put aside the day to upgrade a large app I've spent the better part of a year working on. After 20 minutes of updating on pub, and 2 small code changes I ran flutter upgrade, and got nervous. I've been running tests for an hour, and now I'm going to play the rest of the day.Again, thank you Flutter Team!!!
PS: I spent 17 years on Delphi 7 because we could never upgrade our entire suite of apps to Delphi 8...10...
