Answer 1

have you clean your gradle with ./gradlew clean, run this command in your android directory project and then try ./gradlew build, if build is unsuccessful then try to looking at the log and see what's wrong with your project. based on my previous experience the problem is mostly from the outdated import, if that's the problem then try to update your package

Answer 2

Try to run these two commands:
flutter clean
flutter pub get

Answer 3

Please try upgrading your flutter first using flutter upgrade, then try cleaning your enviroment using flutter clean and then installing all the packages again using flutter pub get. This might fix your issue, you can try debugging your application again.
