flutter_foreground_task Blank White Screen When Opening Closed App

When running the sample project, if you close the app and open the app either by selecting the notification or selecting the app on your device home screen, the app will display a blank white screen.

Can I see a detailed scenario and a screen where the error occurred?

@Dev-hwang When the app is closed and the foreground task notification is pressed, the function onNotificationPressed() will execute while the app is reopened, and then FlutterForegroundTask.launchApp("/resume-route"); will be executed, it seems like there are some issues when executing this function and it will cause the app screen to have a blank white screen. If you look at my console, there seems to have an error message saying: Couldn't find a unique registered media button receiver in the given context. .

I found this StackOverflow post that seems to have the same issue as me: https://stackoverflow.com/questions/73191762/production-build-from-play-store-only-shows-white-screen

Yep, I am the author of the above mentioned post. I also filed a issue in flutter itself (further setup and config data there), however it got closed with the following explanation: "Since this involves issues with a combination of third-party, we are unfortunately not sure how to resolve this issue". The third-party is flutter_foreground_task. https://github.com/flutter/flutter/issues/109100
