In flutter I am using https://pub.dev/packages/flutter_to_airplay/example package to cast videos on apple tv , it works fine but when I switch between apps it stops the video and casting . I have tried to unable the background mode in Xcode but still it pauses the video when some other app is opened 
In flutter I am using the code in this way ,
AirPlayRoutePickerView(
tintColor: Colors.white,
activeTintColor: Colors.white,
backgroundColor: Colors.transparent, )
What I need to change so that the videos keep playing when we switch between apps.
I have tried background modes and flutter pub dev two packages flutter_to_airplay and flutter_ios_airplay but for both videos and the casting stops when I switch between apps , May there is some change in iOS configuration .
