flutter-local-notification - 推送通知的自定义声音不起作用

Question

我为推送通知添加了自定义声音，但它不起作用。我卸载并安装了该应用程序，但仍然无法正常工作。它没有显示任何错误，默认通知也有效。你能告诉我我在哪里失踪吗？

late FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin;
  static const AndroidNotificationChannel channel = AndroidNotificationChannel(
    'high_importance_channel', // id
    'High Importance Notifications', // title
    'This channel is used for important notifications.', // description
    sound: RawResourceAndroidNotificationSound('digitalalarm'),
    playSound: true,
    importance: Importance.high,
  );

  Future<void> initializeService() async {
    flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();
    const AndroidInitializationSettings initializationSettingsAndroid =
        AndroidInitializationSettings('@mipmap/ic_launcher');

    const InitializationSettings initializationSettings =
        InitializationSettings(android: initializationSettingsAndroid);
    tz.initializeTimeZones();
    tz.setLocalLocation(tz.getLocation('Asia/Kolkata'));
    await flutterLocalNotificationsPlugin.initialize(
      initializationSettings,
      onSelectNotification: (payload) async {
        if (payload != null && payload.isNotEmpty) {
          if (await canLaunch(payload)) {
            await launch(
              payload,
              forceSafariVC: false,
            );
          } else {
            throw "Could not launch URL";
          }
        }
      },
    );
    
  Future<void> scheduleNotification(Class _class) async {
    {
      await flutterLocalNotificationsPlugin.zonedSchedule(
        ((_class.deadline?.millisecondsSinceEpoch) ?? 0) ~/ 60000,
        'Reminder: ${_class.subject}',
        'Your assignment is due in 10 minutes',
        // ignore: cast_nullable_to_non_nullable
        tz.TZDateTime.from(
          _class.deadline?.subtract(const Duration(minutes: 10)) ??
              DateTime.now(),
          tz.local,
        ),
        NotificationDetails(
          android: AndroidNotificationDetails(
            _class.id,
            _class.subject,
            '${_class.subject} Assignment reminder',
            importance: Importance.max,
            priority: Priority.high,
            showWhen: false,
            color: _class.color,
          ),
        ),
        androidAllowWhileIdle: true,
        uiLocalNotificationDateInterpretation:
            UILocalNotificationDateInterpretation.absoluteTime,
        payload: _class.link,
      );
      notifyListeners();
    }
  }
