not working in my case
I have tried all of the methods and my app which was working uptil last week is now stuck on white screen while executing from android studio and only on my phone.
there is no error and using adb to unistall package is not helping

I did the above solution, and then did the following in the terminal
flutter clean
flutter pub get
and run the app
