Is it possible to test Flutter online?
By online, I mean similar to testing HTML/CSS/JS in Codepen or Replit.I know that we can run Dart online with Dartpad, so I wanted to know if there are any plans for Flutter to be ran online (I am not taking about Hummingbird).I really think this will be useful for running some quick tests for a particular UI, especially for those with slower computers. It sometimes takes more than a minute for the simulator to launch on my computer.Edit: my main issue is that Flutter and the simulator take too long to start (although hot reload is fast). I will the Flutter Desktop and see if it's any faster

Not so smooth scrolling in List view
@r_FlutterDev, I have created a very basic Listview.builder with a row of FlatButton.icons in each item. For some reason I see10+ frames getting dropped when I scroll. Removing or reducing those icon buttons fixes the problem.I have done everything by the book. It's a very basic example with no other bells and whistles. I created a few other examples of loading images in a long list and it is running super smooth. One when I add this row of FlatButtons that it gets laggy.Really need some help. I think for some reason recreating those Flat buttons is causing frame drops.

Should I migrate to AndroidX and how would I know which plugins have upgraded?
Just got an error that looks AndroidX related -- want to make sure I'm going in the right direction: Should I migrate to AndroidX and how would I know which plugins have upgraded? Are there any major plugins that haven't migrated?​Thanks

What kind of 'fingerprints' does a flutter app leave?
By fingerprints, I mean how can one tell an app was made with flutter. Are there files in the apk that are always included? Or namespaces?To my understanding as Flutter becomes one view that is part of the android app, then one can find this view based on its package name? Or something like this?And if this is true, what methods can be used to hide these prints making it hard to peek into.(motivation behind this question is to give a client some kind of comfort in knowing there app wont be copied so easily when others in their sector find its a flutter app ... since flutter dev is so quick)

What are some practice apps that you'd recommend recreating to learn flutter a bit better?
I think my problem now that I've remade a crappy app that I was working on with kotlin in flutter, I'm kind of out of ideas on things I could make to practice to further my learning experience with flutter/dart.So, if you were to tell someone to practice flutter dev what things would you have them recreate so they could understand different portions of flutter?I word it like that because in the gamedev space you'd have people start with pong just to get a feel of moving things on the screen and basic ai, then move on to something like break for object displacement and a platformer because now you've learned object displacement and how to move an object on screen so you can now collect items and learn basic camera movement & collision detection, etc... just to ease them into learning different portions to gamedev so when they go to make their own game it's like oh you've done collision detection before, so you know how to deal with this problem.

PSA: Visual Studio Code 1.32.2 has been relased and the Flutter/Dart extension is working fine again
Previously, the VSC extension for Flutter development was able to _start_ apps (by pressing F5) but automatic hot reloading wouldn't work. Any other Flutter command (toggle dev layers, dart dev tools, etc) wouldn't work either.The latest version of VSC fixes that and the awesome VSC Flutter dev experience is back.For reference: https://github.com/Dart-Code/Dart-Code/issues/1518

Powerful databinding in Flutter
I started using Flutter a few weeks ago, and it seems fantastic and the future of crossplattform development. But state management and UI Updates always seem to involve a lot of boiler plate code and classes and/or wrapping values of you Code into Oberservable<T> or making it immutable which makes it tenuous to work with the Model. Or you have to call setState so your Model has to know about what UI to update which is also no maintainable. Qlso you can only bind your UI against a local Model, and just just add a line (plugin) to have the Model e.g. in Firestore. If you know about anything like this please let me know, otherwise I am going to develop this library I would love to hear about ideas.Counter Example for my Databinding solution, please note that you can still use any separation of Model, View and Logic just for the simple example I am not going to do it.

class MyApp extends StatelessWidget with Bindable { int get counter => get("counter", 0); set counter(int v) => set("counter", v); @override Widget build(BuildContext context) { return MaterialApp( title: 'Binding Demo', home: Scaffold( body: Center( child: Binding( builder: (c) => Text("You have pressed the button $counter times"))), floatingActionButton: FloatingActionButton( onPressed: () => counter++, child: Icon(Icons.add), ), )); } } 

The Bindable class will make any class Bindable (as a mixin "with") and the Binding Widget will keep the UI up to date without any boilerplate and even be able to know if your UI is bound against a complex function not only simple variables as in this example.Some Advantages:-fastest and simplest way to code, e.g. not wrapping every Value into Oberservable<T> or adding many classes for actions, reducers etc.-Models / Logic should not know about the UI and when it needs to update-only update very small part based on actually changed value-even update parts that get their data from complex functions-can add "plugins" to save data to shared prefs, firestore or add "time traveling" or undo / redo with a library and one line of code.the library will kept extendable so anyone can develop new pluginsTL;DR: Make Statemanagement easier and more powerful
