如何将通知导航到相关页面

Question

我正在尝试在终止、打开时导航通知。我可以在应用程序打开时导航，但不能在屏幕上导航。在主页的initstate方法中，我创建了onMessageOpenedApp方法来捕获通知，然后调用api。这是firebase消息传递配置。

Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
RemoteNotification? notification = message.notification;
AndroidNotification? android = message.notification?.android;
AppleNotification? apple = message.notification?.apple;
if (notification != null && !kIsWeb) {
flutterLocalNotificationsPlugin.show(
notification.hashCode,
notification.title,
notification.body,
NotificationDetails(
android: AndroidNotificationDetails(
channel.id,
channel.name,
),
iOS: const IOSNotificationDetails()),
);
}
}
Future<void> iniciliazarFlutterLocalNotifications() async {
final NotificationAppLaunchDetails? notificationAppLaunchDetails = !kIsWeb &&
Platform.isLinux
? null
: await flutterLocalNotificationsPlugin.getNotificationAppLaunchDetails();
var androidSettings =
const AndroidInitializationSettings('mipmap/launcher_icon');
FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
if (!kIsWeb) {
channel = const AndroidNotificationChannel(
'high_importance_channel', // id
'High Importance Notifications', // title/ description
importance: Importance.high,
ledColor: Colors.blue);
var iOSSettings = const IOSInitializationSettings(
requestSoundPermission: false,
requestBadgePermission: false,
requestAlertPermission: false,
);
var initSetttings =
InitializationSettings(android: androidSettings, iOS: iOSSettings);
flutterLocalNotificationsPlugin.initialize(initSetttings);
await flutterLocalNotificationsPlugin
.resolvePlatformSpecificImplementation<
AndroidFlutterLocalNotificationsPlugin>()
?.createNotificationChannel(channel);
await flutterLocalNotificationsPlugin
.resolvePlatformSpecificImplementation<
IOSFlutterLocalNotificationsPlugin>()
?.requestPermissions(
alert: true,
badge: true,
sound: true,
);
await FirebaseMessaging.instance
.setForegroundNotificationPresentationOptions(
alert: true,
badge: true,
sound: true,
);
FirebaseMessaging.onMessage.listen((RemoteMessage message) {
RemoteNotification? notification = message.notification;
AndroidNotification? android = message.notification?.android;
AppleNotification? apple = message.notification?.apple;
if (notification != null && !kIsWeb) {
flutterLocalNotificationsPlugin.show(
notification.hashCode,
notification.title,
notification.body,
NotificationDetails(
android: AndroidNotificationDetails(
channel.id,
channel.name,
),
iOS: const IOSNotificationDetails()),
);
}
});
}
}

这是我的HomeScreen initState变量，只有我才能导航我的通知，然后调用Api提供者。

class Home extends StatefulWidget {
const Home({super.key});
@override
State<Home> createState() => _HomeState();
}
class _HomeState extends State<Home> {
@override
void initState() {
super.initState();
FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
if (message.data.containsKey('idReferance')) {
Provider.of<CustomerProvider>(context, listen: false)
.getTrackingInformationList(TrackingInformationFilterRequestModel(
searchBox: message.data['idReferance']));
}
});
}
@override
Widget build(BuildContext context) {
return Container();
}

}

有一个名为getInitialMessage的函数，如果应用程序在终止时从通知中打开，它将返回远程通知。如果从其他地方打开该应用程序，它将返回null。您可以根据此远程通知对象处理导航。下面是一个可以使用的示例函数

Future<void> setupInteractedMessage() async {
// Get any messages which caused the application to open from
// a terminated state.
RemoteMessage? initialMessage =
await FirebaseMessaging.instance.getInitialMessage();
// If the message also contains a data property with a "type" of "chat",
// navigate to a chat screen
if (initialMessage != null) {
_handleMessage(initialMessage);
}
// Also handle any interaction when the app is in the background via a
// Stream listener
FirebaseMessaging.onMessageOpenedApp.listen(_handleMessage);
}

您可以从应用程序启动屏幕的initstate或您认为相关的地方调用此方法。有关更多详细信息，您可以在此链接中查看示例https://firebase.flutter.dev/docs/messaging/notifications/#handling-交互
