颤音通知不显示弹出

Question

当应用程序打开时，我会在Firebase中发送通知，并在后台打开，并且封闭的工作正常。

，

但我想弹出，这样：

我的代码；

local_notification_service.dart：

class LocalNotificationService {
  static final FlutterLocalNotificationsPlugin _notificationsPlugin =
      FlutterLocalNotificationsPlugin();

  static void initialize(BuildContext context) {
    final InitializationSettings initializationSettings =
        InitializationSettings(
            android: AndroidInitializationSettings("@mipmap/launcher_icon"),
            iOS: IOSInitializationSettings(
              requestSoundPermission: false,
              requestBadgePermission: false,
              requestAlertPermission: false,
            ));

    _notificationsPlugin.initialize(initializationSettings,
        onSelectNotification: (String? route) async {
      if (route != null) {
        Navigator.of(context).pushNamed(route);
      }
    });
  }

  static void display(RemoteMessage message) async {
    try {
      final id = DateTime.now().millisecondsSinceEpoch ~/ 1000;

      final NotificationDetails notificationDetails = NotificationDetails(
          android: AndroidNotificationDetails(
        "kasifkocaeli",
        "kasifkocaeli channel",
        channelDescription: "kasifkocaeli guzel",
        importance: Importance.max,
        priority: Priority.high,
      ));

      await _notificationsPlugin.show(
        id,
        message.notification!.title,
        message.notification!.body,
        notificationDetails,
        payload: message.data["route"],
      );
    } on Exception catch (e) {
      print(e);
    }
  }
}

main.dart：

Future<void> backgroundHandler(RemoteMessage message) async{
  print(message.data.toString());
  print(message.notification!.title);
}

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  FirebaseMessaging.onBackgroundMessage(backgroundHandler);
  runApp(const MyApp());
}

select_screen.dart：

class _ChoosePageState extends State<ChoosePage> {
  @override
  void initState() {
    super.initState();

    LocalNotificationService.initialize(context);

    //Bildirime tıklandığında gösterilecek mesaj
    FirebaseMessaging.instance.getInitialMessage().then((message) {
      if (message != null) {
        final routeFromMessage = message.data["route"];

        Navigator.of(context).pushNamed(routeFromMessage);
      }
    });

    //forground (uygulama önplandayken)
    FirebaseMessaging.onMessage.listen((message) {
      if (message.notification != null) {
        print(message.notification!.body);
        print(message.notification!.title);
      }

      LocalNotificationService.display(message);
    });

    //Uygulama arkaplandayken ve kullanıcı tıkladığında
    FirebaseMessaging.onMessageOpenedApp.listen((message) {
      final routeFromMessage = message.data["route"];

      Navigator.of(context).pushNamed(routeFromMessage);
    });
  }

Answer 1

如果您在设置对最大的重要性之前运行了该应用程序，则它可能已经被缓存了。我遇到了同样的问题，不得不擦除Android仿真器的数据并再次运行，然后起作用。

Answer 2

您需要打开设置并选择通知，转到您的应用程序，然后在屏幕底部选择“打开频道名称”，然后tick允许浮动通知

Answer 3

对我来说，我的代码编写正确，我要做的就是运行：

1. flutter Clean
2. flutter Pub get
3. flutter Run

使其正常工作。

基本上，@Ricky Kresslein说的话。
