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 IMarch 14, 2021 at 12:01PM by md186 https://ift.tt/3bLYWvM

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.

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!

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 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.

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?

Generated classes
I try to sync data via GraphQL from my backend. Therefore I use the artemis package to generate my classes. However I then want to cache the data localy and therefore use the sqfentity_gen package to generate classes to safe my data via sql. I can use a json constructor with each framework to convert the data between.However I want to encapsulate certain functionality since I dont want to just safe changed data localy but sync it to the backend and handle certain errors like merge conflicts or missing network. Therefore I am thinking about wrapping the classes with an other one since I cant change the generated code. Is this a good idea or are there other solutions which work better? Would you use a completly diffrent setup? Glad for any ideas

Best way to have a list with self updating children (which the amount of can change constantly)
Hello everyone,I'm building a qBittorrent controller in Flutter. Now I do have something that functions, but it does throw a few exceptions of the way I set it up and I don't know how to make it better, since I'm self thought. So I'm hoping you guys can help me or point me to something that already exists, here's the explanation:The app gets a list of torrents from the server. It then sorts these based on whether they are active and creates children with a ChangeNotifier to keep the values updated (1s if they are active, longer if they are not). This means the class that holds all the torrents also has to update to check if new ones are added or if the torrent went inactive and needs to reorder the list. This comes with a problem that if a torrent is removed or changed lists it gets removed from the widget tree, but the repeating update call gets executed in a ChangeNotifier that doesn't exist anymore. Also when a regroup happens a lot of widgets are rebuild that probably didn't change. This also means any state, for example if a child has been selected to show more information gets discarded every so many seconds.I'm not sure what a good way of handeling the data, displaying new data and keep them ordered would be, since I just lack experience. I hope it is clear enough. If you need more information do let me know!Thanks in advance :)
