I tried releasing the app to firebase app distribution using fastlane and when I run the app, it throws an error saying that ProviderScope is not found. The app has been made on top of Riverpod state management.
When I run the app in debug or release mode, it works absolutely fine. Furthermore, I also created a manual build an it also magically works perfectly. Just having issue with Firebase App Distribution.
As I suggested, and later as Shrijan Regmi pointed out, the problem was in multiple entry points, i.e. there are multiple different main.dart files. And the wrong entry point was used for the build.
