为什么从firebase发送的通知接收延迟

Question

以下是在颤振中监听通知的代码，我正在从 firebase 控制台发送通知

    FirebaseMessaging.onMessage.listen((RemoteMessage message) {
      RemoteNotification notification = message.notification;
      AndroidNotification android = message.notification?.android;
      if (notification != null && android != null) {
        flutterLocalNotificationsPlugin.show(
            notification.hashCode,
            notification.title,
            notification.body,
            NotificationDetails(
              android: AndroidNotificationDetails(
                channel.id,
                channel.name,
                channel.description,
                color: Colors.blue,
                playSound: true,
                icon: 'ic_launcher',
              ),
            ));
      }
    });

请详细解释一下，当应用打开时您无法收到通知的实际问题是什么，那么您必须使用本地通知插件才能在应用打开时在应用上显示通知
