Pub get has not been run

I installed the flutter in my windows 11. When I open the new flutter project, after installing the flutter plugins, I got this error 'Pub get has not been run '.
I also clicked on get dependences and upgrade dependencies. But still getting the error.
Is there any solution.
This is a known bug in Android Studio. The message disappears, when I disconnect my phone from my MacBook and plug it in again. You could also try to restart Android Studio, use flutter pub get in your terminal or just press ignore.

Error: Target of URI doesn't exist: 'package:flutter/material.dart'. (uri_does_not_exist at [myapp] test/widget_test.dart:8)

I made an app in Flutter and there are no errors on its Dart file but I suddenly end up with errors on widget_test.dart. can you guys help me out. Thanks
Run flutter clean, and then flutter pub get in the terminal respectively.
If that doesn't work, try running flutter upgrade, and then repeating the initial steps.
Finally, if it still isn't working, you can run flutter doctor to see if there's anything glaringly wrong with your project.

I was also facing the same error, but it was always on my test folder.
This is what I did:
On your terminal, make sure you are in your project repository.
Run the flutter pub get command, it worked for me, may be you
should try it too.
Do you possibly have two different versions of the Flutter SDK on your machine? I wonder if one is being used by flutter create and the other for analysis.
If you're sure you only have one, please open an issue on GitHub and attach a log file for me to investigate.
