firebase - 在 Flutter 上单击背景通知时如何导航？

Question

单击 时是否可以导航到指定路径背景 FCM 通知？
我创建了一个 顶级功能并将其添加到导航器路径但它不起作用，当单击后台通知时，它只是打开应用程序
我想我发现了一个问题

Now, I changed fcm configuration from home page to splash screen. The foreground doesn't navigate to the page, I think its because the Splash Screen is no longer available. When I click on the notification message, it just opens the app.

FCM 配置

onBackgroundMessage: backgroundMessageHandler

顶级功能

Future<dynamic> backgroundMessageHandler(Map<String, dynamic> message) {
  if (message.containsKey('data')) {
    getIt<NavigationService>().navigateTo('/${message['data']['screen']}');
  }
}

有效载荷

const payload: admin.messaging.MessagingPayload = {
                notification:{
                    title: `New Enquiry`,
                    body:`${customerName} published to ${subName}`,
                    badge: '1',
                    sound: 'default'
                },
                data: {
                    click_action: `FLUTTER_NOTIFICATION_CLICK`,
                    sound: `default`,
                    status: `chat`,
                    screen: `homePage`
                  }
            }

main.dart

GetIt getIt = GetIt.instance;

void main() {
  setupLocator();
    runApp(MyApp());
}

MaterialApp

 return MaterialApp(
      navigatorKey: NavigationService().navigatorKey,
      onGenerateRoute: Router.generateRoute,
    );

导航服务和 设置定位器

class NavigationService {
  final GlobalKey<NavigatorState> navigatorKey =
      new GlobalKey<NavigatorState>();

  Future<dynamic> navigateTo(String routeName) {
    return navigatorKey.currentState.pushNamed(routeName);
  }
}

void setupLocator() {
  getIt.registerLazySingleton(() => NavigationService());
}

要处理来自后台状态的通知，您可以使用 FirebaseMessaging 库公开的流。

FirebaseMessaging.onMessageOpenedApp.listen((remoteMessage) {
  // Handle navigation or perform any logic here
});
