When i try to open most of downloaded flutter app in android studio it keeps telling me 'Pub get' has not been run and when i press 'get dependencies' or upgrade dependencies' it shows me that error . I have upgraded android studio and flutter and dart to the latest version
Error :
C:\Dart\dart-sdk\bin\pub.bat get
Resolving dependencies...
Because wisgen depends on flutter_test any from sdk which doesn't exist (the Flutter SDK is not
available), version solving failed.
Flutter users should run `flutter pub get` instead of `pub get`.

Go to the top menu 'Tools > Flutter > Flutter Clean'
Normally there is a problem with Flutter SDK not being set up (can be other problems too)

You need to use TickerProviderStateMixin/SingleTickerProviderStateMixin to get vertical-sync
like
class _FAState extends State<FA> with SingleTickerProviderStateMixin {
late final controller = TabController(length: 3, vsync: this);
Also you can use initSate instead of late.
I got this error after logging in with google.
I have looked for many solutions on the Internet for 2 days but none of them solved the problem. I opened a new project and transferred it there, but it didn't work either.
Some of the methods I use:
1-flutter clean,flutter build apk
2-flutter run -verbose
3-Delete Android/.gradle
4-dart fix --dry-run,dart fix --apply

These are warnings of the Gradle compiler plugin. It checks whether your code (or code of your dependencies) uses deprecated function calls at some point.
In your example, the code which uses deprecated features is part of libraries provided by Google.
Deprecation means, that the provider of a specific library emphasizes on not using a specific method as it may be removed in future releases.
There is not much you can do, if the message relates to code that you don't maintain. You could inform the maintainer of the library, though.
The build seems to succeed. During runtime, there seems to be an issue with the MainActivity – there are multiple reasons why this happens:
Flutter app is not runnig on physicial device
Error type 3 Error: Activity class {} does not exist
The current Flutter SDK version is 0.0.0-unknown.
Because provider 5.0.0 requires Flutter SDK version >=1.16.0 and no versions of provider match >5.0.0 <6.0.0, provider ^5.0.0 is forbidden.
So, because flutter_app depends on provider ^5.0.0, version solving failed.
Pub get failed (1; So, because flutter_app depends on provider ^5.0.0, version solving failed.)
That's the error I’m getting when trying to run 'flutter pub get' in Android Studio.

Your Flutter probably had a problem while installing.
You can use Git commands to fix it.
Run these commands on your Flutter SDK, not on your project files.
git clean -xfd
git stash save --keep-index
git stash drop
git pull
flutter doctor
You can check this thread on GitHub.
Go to the terminal and upgrade the SDK version by the
flutter upgrade
Command. This command is for both Mac and Windows.
If it shows an error, run
flutter upgrade --force
I have created an app with flutter and firebase and i am trying to create the build apk. but i get error when running flutter build apk. i think it is because my google sign in is not setup for release.
