some methods reduce playing music volume

[meowofficial]

addListener, setIOSAudioSessionCategory reduce volume of currently playing music. Minimization of application reverts music volume back. Resuming of application doesn't reduce volume again.

FlutterVolumeController.addListener(
      print,
      stream: AudioStream.music,
      category: AudioSessionCategory.playback,
      emitOnStart: true,
);

await FlutterVolumeController.setIOSAudioSessionCategory(
      category: AudioSessionCategory.playback,
);
