flutter - 在前台隐藏颤振本地通知

Question

我想在应用程序处于前台时隐藏通知，但 IOS 即使在前台也显示通知。通常，当应用程序处于前台时，不会显示 FCM 通知。这是我的代码

await flutterLocalNotificationsPlugin
        .resolvePlatformSpecificImplementation<
            AndroidFlutterLocalNotificationsPlugin>()
        ?.createNotificationChannel(channel);

    AndroidInitializationSettings androidInitializationSettings =
        AndroidInitializationSettings('@mipmap/ic_launcher');
    IOSInitializationSettings iosInitializationSettings =
        IOSInitializationSettings();

    InitializationSettings initializationSettings = InitializationSettings(
        android: androidInitializationSettings, iOS: iosInitializationSettings);

    flutterLocalNotificationsPlugin.initialize(initializationSettings,
        onSelectNotification: onSelectNotification);

    final bool? result = await flutterLocalNotificationsPlugin
        .resolvePlatformSpecificImplementation<
            IOSFlutterLocalNotificationsPlugin>()
        ?.requestPermissions(
          alert: true,
          badge: true,
          sound: true,
        );

Answer 1

只需要添加这一行

await FirebaseMessaging.instance.setForegroundNotificationPresentationOptions(
    alert: false,
    badge: false,
    sound: false,
  );

Answer 2

如果您不想在前台看到通知，请将您的代码仅添加到onBackgroundMessage处理程序中。
