Can't find main.dart as entrypoint, how to connect Android project to the main.dart file?

Question

Please don't mark as a duplicate. I have tried to read this Flutter : Target file "lib/main.dart" not found but I have found no answer, because what I ask will be little different

so I have this error when I run my Flutter App through the Android project (from Android Studio), I mean for some reason I did not run the project through the Flutter project (not from VS Code). I have no issue If run my Flutter app through VS Code

this is the error

Error: Error when reading 'lib/main.dart': No such file or directory import 'package:mobile/main.dart' as entrypoint

so basically the Android Studio can't find the main.dart.

I implement Flavor on my Flutter, so I have several main functions such as main_production.dart, main_staging.dart and main_development.dart instead of normal main.dart . thats why the system can't find the entry point.

In iOS Xcode, I can set the main entry point through Flutter Target like this

but now I am confused, how to connect my Android project to the several main function (my dart files)

Answer 1

In android studio, open action menu with (cmd+shift+a on mac and ctrl+shift+a on windows/linux) and select Edit configurations

Then, using a plus sign at the top, add a new flutter run config

And specify an appropriate entrypoint and flavor:

All that's left is to run the new config using either of the green buttons at the top (run or debug)
