Why is the notification bar's button not updating to a play button when I tap the pause button

Question

When I use the Audio_service package in Flutter on my Android 11 device, clicking the playback pause button in the Flutter UI is valid, but clicking the buttons other than the pause button in the notification bar button is valid, and the notification bar buttons will not update after clicking the pause button I tried printing the value of playbackState.value.controls but it is correct [{androidIcon: drawable/audio_service_skip_previous, label: Previous, action: 4}, {androidIcon: drawable/audio_service_play_arrow, label: Play, action: 2}, { androidIcon: drawable/audio_service_skip_next, label: Next, action: 5}], the printed result is the play button but the pause button is still displayed in the notification bar, and the pause operation will still be performed after clicking

This is my code

 @override
  Future<void> stop() async {
     print(playbackState.value.controls);
    playbackState.add(playbackState.value
        .copyWith(playing: false, controls: [MediaControl.skipToPrevious, MediaControl.play, MediaControl.skipToNext]));
    await player?.stop();
     print(playbackState.value.controls);
  }

  @override
  Future<void> seek(Duration position) async {
    player?.seek(position);
     print(playbackState.value.controls);
  }

  @override
  Future<void> play() async {
    if (player == null) {
      if (curindex != null) {
        playnew(curindex!);
      }
    } else {
      playbackState.add(playbackState.value.copyWith(
        playing: true,
        controls: [MediaControl.skipToPrevious, MediaControl.pause, MediaControl.skipToNext, MediaControl.stop],
      ));
      await player?.play();
    }
  }

  @override
  Future<void> pause() async {
    playbackState.add(playbackState.value.copyWith(
      playing: false,
      controls: [MediaControl.skipToPrevious, MediaControl.play, MediaControl.skipToNext],
    ));
    await player?.pause();
  }
