[bug] Screenshare freezes the app #997
Description
Describe the bug
setScreenShareEnabled causes the application to freeze. Sometimes it happens even the first time it’s called, and in other cases the app freezes after, for example, enabling and disabling screen sharing around 10 times. it freezes the app randomly between 1 or 20 call setScreenShareEnabled!
To Reproduce
await MeetUtils().requestBackgroundPermission();
await lp.setScreenShareEnabled(true, captureScreenAudio: true);
await Navigator.of(context).pushNamed('/paint');
await lp.setScreenShareEnabled(false, captureScreenAudio: false);
await FlutterBackground.disableBackgroundExecution();
Expected behavior
Enable or disable as user needs, without freeze
