调试模式下一切正常，如果我运行flutter运行--release。但是如果我生成release build并使用它运行，自定义声音就不工作了。我使用flutter。
这是代码，

Future _showNotificationWithSound(title, message) async {
    var vibrationPattern = Int64List(4);
    vibrationPattern[0] = 0;
    vibrationPattern[1] = 1000;
    vibrationPattern[2] = 5000;
    vibrationPattern[3] = 2000;

    var androidPlatformChannelSpecifics = AndroidNotificationDetails(
        'added_my_channel_id',
        'abc',
        'abc',
        icon: 'app_icon',
        playSound: true,
        sound: RawResourceAndroidNotificationSound('notifiysound'),
        vibrationPattern: vibrationPattern,
        enableLights: true,
        color: const Color.fromARGB(255, 255, 0, 0),
        ledColor: const Color.fromARGB(255, 255, 0, 0),
        ledOnMs: 1000,
        ledOffMs: 500);

    var iOSPlatformChannelSpecifics =
    IOSNotificationDetails(sound: 'notifiysound.mp3');
    var platformChannelSpecifics = NotificationDetails(
        androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
    flutterLocalNotificationsPlugin. show(
        0, title, message,platformChannelSpecifics);
  }
