Can anyone point me to detailed explanation on Flutter (Dart) instances creation and storage system?
Hello,I'd like to know if Flutter/Dart instances are virtual and to read more about objects and instantiation.I googled a lot and I think the material found is too superficial.Best,GS333

Help: GetX + Firebase Auth + Firestore full example
I use Firebase in nearly all of my Flutter projects and I know it's quite common. I have also been looking into GetX (Provider before that) and have no problem finding either Firebase Auth or Firebase Firestore examples - but never a complete example of everything working together.The most common seems to be to subscribe to the authStateChanges and when the user is null - pop off all pages until the Login page.
Get.offAll(() => LoginScreen()); 
`And I do like this pattern - it's easy. All you need to do is logout and the navigation takes care of itself.But in my examples I have, say a HomeScreen that subscribes to a stream from Firestore and when I signout the first thing that happens is the app crashes because of a Firestore permissions error.Now, I can do this with a StreamBuilder and handle that specific issue and just render an empty container, but that seems like a hack.Here is a StackOverflow post with more code: https://stackoverflow.com/questions/68840299/firebase-firestore-query-with-getx-and-firebase-authDoes anyone have any "best practices" using State Management (GetX) + Firebase Auth + Firebase Firestore with navigation?

Minimum specifications to run Android Studio smoothly
What are the minimum specifications for a machine to run Android Studio smoothly? I tried tips from S.O and other places to try to speed it and Intellij up but it did not work. I am on a Lenovo Ideapad 3 with Core i3 10th Gen, 8 Gigs of Ram, SSD running Ubutnu 20.04.I started a new job remotely and my boss said, "Unless you are much better in VSCode, it is easier to trace bugs and errors if we are all using Android Studio".I am not going to argue with my boss as it is a hierarchical company in Asia where that is frowned upon. So I want to buy a new machine if necessary.

Is it possible to integrate JS in Flutter to render and interact with it on all platforms?
Hello flutter community! Greetings!!I am a bit new to Flutter. But I have little to zero knowledge about web technology. I want to integrate a JS library to render and interact with items on the screen - say something like chart.js or pdf.js as an example. As far as I understand, if I need to only manipulate data or do backend stuffs related to JS engine, I can use flutter_js which is available on all platforms. But if I need to render the graphics and interact with it via JS, it is a totally different thing? I need to use platform specific plugins. For web, I can use JS plugin for flutter. For android and IOS, I need to use webview_flutter plugin as seen in high_chart example. If that is so, is there any options for windows and macos?

Map and null safety: <String, dynamic> to <String, Object> or <String, Object?>
Hello fellow developers :)So I have finally managed to migrate my project to null-safety (over 30k errors, phew...) and now I cannot decide on what's the proper replace for Map<String, dynamic>. I know that dynamic should be replaced with Object in null safety world. I also have extensions for Map objects and currently I'm using it like this: extension MapHelpers on Map<String, Object?> and for my serialization code I also use fromMap/toMap with <String, Object?> parameter type.What do you guys use? Do you use <String, Object> or <String, Object?> ? Is there even a benefit for having that Object optional?Thanks for your thoughts!Edit: The man reason I started with <String, Object?> is that I can put optionals to that map. If I try to put, let's say a property that is a type of String? into <String, Object> - the compiler doesn't allow that.
