Solution 1:[1]
Try this:
- Close project.
- Go to project repository folder.
- Delete all generated files, for example:
- .dart_tool
- .idea
- .build
- .flutter-plugins
- .flutter-plugins-dependencies
- .metadata
- .packages
Nothing should changed in your git changes due to .gitignore file
Open Android Studio again
Go to File->Invalidate Caches/Restart, then invalidate caches and restart
if your project structure is corrupted go to: File -> Close Project, close project and reopen it, it should be back to normal.
Run all the necessary scripts starting with:
flutter pub get
dart pub get
Solution 2:[2]
For me the thing was to delete android/app/build folder and run flutter clean.
Solution 3:[3]
Working solution:
Just uninstall/remove the entire flutter SDK folder and reinstall the same version of a flutter you have currently from the below link.
Flutter SDK as per version: https://flutter.dev/docs/development/tools/sdk/releases?tab=macos
After the new flutter is installed. Just do flutter clean and run the app.
Solution 4:[4]
For my case, I found my code incompatible with my flutter version as I used flutter upgrade once. So I had to downgrade (delete the flutter folder manually in your src folder and extract the version that supports my code) my flutter sdk in C:\src\flutter to the version that my app supports. After running flutter clean (which just deletes the files that flashrow has mentioned) it got solved for me.

2022 Working Solution
I got the same error after running my app on a physical device. This may happen if the compile SDK version is lower than that of the physical device. This error message is not limited just to running on physical devices however, here is the solution.
Go to android/app/build.grade
Find
android {
compileSdkVersion 30 //Or whatever version it currently is
The change the compileSdkVersion to 31
android {
compileSdkVersion 31
In the future, the maximum compileSdkVersion might increase, so try 32, or 33 if it doesn't work
Solution 6:[6]
Try to run with the -v parameter to see a better logging console. In my case, some plugins are generating the following error:
Cannot run with sound null safety, because the following dependencies
When I saw it, I run with the option --no-sound-null-safety and I could start my app in the emulator.
Solution 7:[7]
Apperently this seems like a null safety related issue. lowering down the Dart sdk's version from pubspec.yaml could solve this issue.
flutter channel stable
flutter upgrade
## pubspec.yaml
environment:<br>
sdk: '>=2.0.0 <3.0.0'
