After a Flutter upgrade, I am getting the error "Could not resolve all files for configuration ':app:debugRuntimeClasspath'"

Question

When I upgraded Flutter from Flutter 2.10.2 to a newer version, I got this error on every Flutter project I had created. Even when I created the new Flutter project (the simple counter app) when I am going to run the app, I am getting this error.

Execution failed for task ':app:checkDebugAarMetadata'.

If you're not running on stable channel, try switching to stable and run an upgrade.

flutter channel stable && flutter upgrade

Then download the project dependencies and run the app again.

flutter clean
flutter pub get
flutter run
