How to handle background music while playing muted video in Flutter?

I have a Flutter app. On opening the app, the app will play a muted video, till here it's perfectly fine. But when I play music in Spotify in the background, and then I try to open my Flutter app, Spotify pauses the background music. So all I want is, to keep Spotify playing music in background while the video in my app keeps playing muted. And when I try to unmute the video in my app, the Spotify music must pause.

videoPlayerController = VideoPlayerController.asset(ConstantAssets.dummyVideo3)
    ..addListener(() {})
    ..setLooping(true)
    ..initialize().then((value){
      videoPlayerController.play();
      videoPlayerController.setVolume(0);
    });

So, the concept is like "Playing video Instagram" while listening to Spotify in the background. Is it possible to do something like that?
