可以使用NotFification Tap导航到特定页面。飘扬的深链接问题

Question

//root dart file

  FirebaseMessaging.onBackgroundMessage(_backgroundMessageHandler); 
  await NotificationService.instance.initializeNotifications();

  Future<void> _backgroundMessageHandler(RemoteMessage message) async {
  await Firebase.initializeApp();
 }

//In, NotificationService file, I have initialized 
 AwesomeNotification(awesome_notification package),and have 

  //This handles notification actions

  AwesomeNotifications().actionStream.listen((notification) async {
  print(notification.payload);
  if (notification.payload != null) {
    final payload = notification.payload!;
    if (payload['type'] == 'vaccine-records') {
      _appRouter.root.innerRouterOf(DashboardRouter.name)
        ?..innerRouterOf<TabsRouter>(DashboardRoute.name)?.setActiveIndex(2)
        ..navigate(
          VaccineRecordsRouter(
            petId: int.parse(payload['id']!),
            petType: int.parse(payload['pet_type']!),
            petName: notification.title,
          ),
        );
    }
  }
});

 //this listens to new notification from Firebase cloud messaging

FirebaseMessaging.onMessage.listen((message) async {
  print(message.data);
  if (message.data.isNotEmpty) {
    await AwesomeNotifications().createNotificationFromJsonData(message.data);
  } else {
    print('here');
    await AwesomeNotifications().createNotification(
      content: NotificationContent(
        id: 0,
        channelKey: 'basic_channel',
        title: message.notification?.title,
        body: message.notification?.body,
        showWhen: true,
        displayOnForeground: true,
        displayOnBackground: true,
      ),
    );
  }
});
}

当我点击通知时，它将带我进入应用程序的主页。我想要它 将我导航到其他屏幕。当该应用在前景中时，我收到 通知，这将我带到所需的页面。但是当应用在后台 并收到了通知，这需要我进入主页。这是如何发生的 从两次开始，我都会得到awesomenotification（）。ActionStream.Listen（（通知） 异步{}执行？

我建议您根据通知的有效载荷使用Firebase动态链接将用户发送到特定页面。

在您当前的情况下，

仅当应用在前景时才触发onMessage函数。

必须处理3个州的通知。

• 当应用在
• 应用时，当应用在App在后台
• 终止

时，请使用以下内容：

//when app is terminated
  FirebaseMessaging.instance.getInitialMessage().then((value) {
    if (value != null) {
      _onNotificationMessage(context, value); // custom function to handle notification
    }
  });

//when app is in foreground
  FirebaseMessaging.onMessage.listen((message) {
    _onProcessMessage(context, message); // custom function to handle notification
  });

//when app is in background
  FirebaseMessaging.onMessageOpenedApp.listen((message) {
    _onNotificationMessage(context, message); // custom function to handle notification
  });
}
