Which would be faster to learn and implement for a python programmer: Flutter or Ionic
I only know python and I think I'm pretty decent at it. Given that, I want to make a mobile app. Ive broken down my options to Ionic or Flutter. If I go with Ionic I have to learn css/html/javascript. If I go with flutter I have to learn dart. Which option would be the faster for me to learn and implement an app given I'm coming from only python? Anyone with relevant experience that can provide insight here?

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);```

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
