Is it possible to set preferredIOBufferDuration for `AVAudioSession`

[ctwdtw]

In native iOS we can set preferredIOBufferDuration:

let audioSession = AVAudioSession.sharedInstance()
let preferredIOBufferDuration: TimeInterval = 1.0 / audioSession.sampleRate * Double(self.BUFFER_SIZE)
try audioSession.setPreferredIOBufferDuration(Double(preferredIOBufferDuration))

Do we have an interface in the AudioSession class for doing that?

Same for setPrefersNoInterruptionsFromSystemAlerts

Not yet. You can see in lib/src/darwin.dart that this is currently commented out as a TODO item for perhaps a contributor to pick up:

  //Future<Duration> get preferredIoBufferDuration async {
  //  return Duration.zero;
  //}

  //Future<void> setPreferredIoBufferDuration(Duration duration) async {}

You are welcome to try your hand at implementing the additional methods you need and submit it as a PR.
