After upgrading flutter, if I run the app from Android studio, I am consistently getting black screen. And If we create release bundle then opening the app and closing we are getting black screen 2 in 5 times.

And when shared the play console internal testing, after install and first open it is stuck at black screen and until user kills the app and reopen then it is opening. Even in this case also once in 3 times of closing and opening it is giving black screen.

EDIT: One more observation I found is, if I declare splashscreen drawable in manifest file, then the splash screen is coming up and then immediately black screen is coming and the app is stuck.

<meta-data android:name="io.flutter.embedding.android.SplashScreenDrawable"
                android:resource="@drawable/launch_drawable" />

UPDATE: After day of debugging and narrowing it down, finally found the culprit. This was present in MainActivity.java, apparently it was added to handle the black screen in older versions of flutter, but now this lead to complete stuck.

    @NonNull
    @Override
    protected FlutterActivityLaunchConfigs.BackgroundMode getBackgroundMode() {
        return FlutterActivityLaunchConfigs.BackgroundMode.transparent;
    }
