CodePudding user response：

Something that work for me is: Delete your pubspec.lock, and press 'Pub Get' in your pubspec.yaml, it'll regenerate pubspec.lock file again and should fix the problem.

CodePudding user response：

Try these commands and try again:

flutter create .
flutter clean
flutter pub get
