Audio file does not play in the IOS Simulator

Question

Hi I am developing a flutter application. In this application some sounds are downloaded from my website and saved to the local file storage. It plays when some pictures are showed.

This works in Android phone properly. But I cannot do it in IOS Simulator. I have controlled whether the files are downloaded properly. I have looked simulator files and saw sound files, so they are properly downloaded. My playing sound code is like that.

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");
  }

In this code the program waits in this line and not doesn't go to the next lines. await advancedPlayer.onPlayerCompletion.first; I don't see any errors.

I have printed sound file path and controlled it, it is in the file storage. Format of audio file is mp3.

In my pubspec.yaml file I have tried 0.17.4 and 0.16.2 versions. I cannot use 0.18.x versions(because other packages dont let me)

audioplayers: ^0.17.4

Thank you so much
