  Future<void> function() async {
    if (disposed) {
      throw AssertionError('[Player] has been disposed');
    }
    await waitForPlayerInitialization;
    await waitForVideoControllerInitializationIfAttached;

    // Do nothing if currently present at the first or last index & playlist mode is [PlaylistMode.none] or [PlaylistMode.single].
    if ([
          PlaylistMode.none,
          PlaylistMode.single,
        ].contains(state.playlistMode) &&
        state.playlist.index == 0) {
      return;
    }

    await play(synchronized: false);
    final command = 'playlist-prev'.toNativeUtf8();
    mpv.mpv_command_string(
      ctx,
      command.cast(),
    );
    calloc.free(command);
  }
