Android 当应用程序位于前台时，flatter_local_通知会锁定系统托盘中的通知

这是我的密码。onLaunch和onResume工作正常，但当我使用flift\u local\u push通知显示来自FCM的通知时，当应用程序位于前台时，通知显示并工作正常，但在系统托盘中得到锁定，并且在刷卡时不会消失

    @override
    void initState() {
    super.initState();
    debugPrint('homebar ka init chal raha hai');
    _fm  = FirebaseMessaging();

    _fm.configure(
    onMessage: (Map<String, dynamic> message) async {
    print("onMessage: $message");
        var json = message['notification'];
        showNotification(json['title'],json['body']);
     
      },
        onBackgroundMessage: myBackgroundMessageHandler,
     
       onLaunch: (Map<String, dynamic> message) async {
           print("onLaunch: $message");
           requestRecieved();
          
      
      },
      onResume: (Map<String, dynamic> message) async {
          print("onResume: $message");
          requestRecieved();

         
         }
      );
   


    // debugPrint('show notification method is working');
    flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();
    var androidInitializer = AndroidInitializationSettings('@mipmap/ic_launcher');
    var iosInitializer = IOSInitializationSettings();
    var generalInitializer = InitializationSettings(androidInitializer, iosInitializer);
    flutterLocalNotificationsPlugin.initialize(generalInitializer,onSelectNotification: (value)
    {
        // setPage.setPageValue(2);
    }
    );


    super.initState();
    }

     showNotification(String title,String body)
                 
                 {
                   debugPrint('shownotification chal raha hai');
                  
                   var androidSettings = AndroidNotificationDetails('fcm_default_channel',                                                                                'channelName', 'channelDescription',
                   importance: Importance.Max,
                     priority: Priority.Max,
                     ongoing: true,
                     autoCancel: true
                     
                   );
                   var iosSettings = IOSNotificationDetails();
                   var platform   = NotificationDetails(androidSettings, iosSettings);
                  newNo tify.setNotificationValue(true);
                  flutterLocalNotificationsPlugin.show(0, title,body, platform);
                 }
