嗨，我正在开发一个Flutter应用程序。在这个应用程序中，一些声音从我的网站下载并保存到本地文件存储。显示某些图片时播放。
这在Android手机上正常工作。但是我不能在IOS模拟器中这样做。我已经控制了文件是否正确下载。我已经看过模拟器文件和声音文件，所以它们被正确下载。我的演奏代码就是这样的。

Future play(File soundFile) async {
    debugPrint("sound: play enter");
    try {
      await advancedPlayer.stop();
      advancedPlayer.setReleaseMode(ReleaseMode.RELEASE);
      if (soundFile != null) {
        print(soundFile.uri);
        advancedPlayer.play(soundFile.uri.toString(), isLocal: true);
        await advancedPlayer.onPlayerCompletion.first;
        debugPrint("sound: played");
        // advancedPlayer.stop();
      }
    } catch (e) {
      debugPrint("sound: error");
    }
    debugPrint("sound: play leave");
  }

在这段代码中，程序在这一行等待，而不会转到下一行。await advancedPlayer.onPlayerCompletion.first;我没有看到任何错误。
我已经打印了声音文件路径并控制它，它在文件存储中。音频文件格式为mp3。
在我的pubspec.yaml文件中，我尝试了0.17.4和0.16.2版本。我不能使用0.18.x版本（因为其他软件包不允许）

audioplayers: ^0.17.4

太谢谢你了
