Every time I try running pub get or pub upgrade the following error is returned:[Working dir: C:\Users\User\AndroidStudioProjects\flutterr_app "C:\Program Files\Dart\dart-sdk\bin\pub.bat" get ) was unexpected at this time. Process finished with exit code 255][1]

In your project open terminal and write flutter pub get. it should remove all the errors. If not, share your pubspec.yaml code.

It's very common to have this error. Running flutter pub gets all the dependencies.

Looks like a problem with your Dart SDK path. Open Android Studio, Go to File->Settings. Scroll down to bottom and select Language & Frameworks. Click on dart and share your Dart SDK path.
