（MissingPluginException（在通道xyz.luan / audioplayers上未找到方法setNotification的实现））

Question

我正在为我的音乐应用程序使用audioplayers 0.16.1库，但是在生成通知时不断出现以下错误。我的错误代码：

Exception has occurred.
MissingPluginException (MissingPluginException(No implementation found for method setNotification on 
channel xyz.luan/audioplayers))

我的setNotification方法：

  setNotification() async {
await advancedPlayer.setNotification(
    albumTitle: "Beatifun Music",
    artist: video.snippet.channelTitle,
    duration: _duration,
    elapsedTime: _position,
    backwardSkipInterval: Duration(seconds: 10),
    forwardSkipInterval: Duration(seconds: 10),
    imageUrl: video.snippet.thumbnails.high.url,
    title: video.snippet.title);
    }

我该如何解决这个问题？
