Black Screen when using flutter_windowmanager with flutter_pdfview in oppo devices only

Closed this issue 3 years ago · 6 comments

I am using flutter_pdfview package
I found a black screen with it in oppo devices only , in all other devices it works perfectly.

dependencies:
flutter_pdfview: ^1.0.4
flutter_windowmanager: ^0.0.2

Function which called in main() to apply on the whole app
Future secure() async {
await FlutterWindowManager.addFlags(FlutterWindowManager.FLAG_SECURE);
}

This is my flutter doctor -v

As this package simply toggles a flag at the Android level, you may have encountered an Android bug for this particular device. I would suggest trying to reproduce this using native Android code and if the problem persists, file a bug with the device manufacturer. If you're not sure how to do this natively, take a look at the onMethodCall() function in android/src/main/java/io/adaptant/labs/flutter_windowmanager/FlutterWindowManagerPlugin.java.

There is an on-going issue tracking this specific problem at flutter/flutter#62333

At this point, it appears to be a device-specific bug, so you should escalate this with your device manufacturer. I will tentatively close this issue here for now, but feel free to re-open should there be new information to go on.
