Implementation

Future<void> setPlaybackSpeed(double speed) async {
  if (speed < 0) {
    throw ArgumentError.value(
      speed,
      'Negative playback speeds are not supported.',
    );
  } else if (speed == 0) {
    throw ArgumentError.value(
      speed,
      'Zero playback speed is not supported. Consider using [pause].',
    );
  }
  _throwIfNotInitialized('setPlaybackSpeed');
  // Setting the playback speed on iOS will trigger the video to play. We
  // prevent this from happening by not applying the playback speed until
  // the video is manually played from Flutter.
  if (!value.isPlaying) return;
  value = value.copyWith(playbackSpeed: speed);
  await vlcPlayerPlatform.setPlaybackSpeed(
    _viewId,
    value.playbackSpeed,
  );
