我在我的 Flutter 应用程序中使用 Firebase 消息传递,即使我的应用程序处于前台或后台,我也想在点击通知时导航到另一个屏幕,我使用了很多功能,但它不会触发点击事件,我可以找不到任何东西可以解决我的问题。
当我在应用程序处于前台或后台时单击通知时,没有任何反应,因为它导航到同一页面。 当我在应用程序终止时单击通知时,它会在启动画面上打开并转到主页而不是我想要的屏幕。
我在我的 Manifest
中添加了这个 intent-filter
<intent-filter>
<action android:name="FLUTTER_NOTIFICATION_CLICK" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
然后我将其添加到 Json
对象
"click_action": "FLUTTER_NOTIFICATION_CLICK",
下面是如何在 main.dart
const AndroidNotificationChannel channel = AndroidNotificationChannel(
'high_importance', // id
'High Importance Notifications', // title
importance: Importance.high,
playSound: true);
final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
FlutterLocalNotificationsPlugin();
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
SessionManager sessionManager = SessionManager();
await Firebase.initializeApp();
//final sound = 'sound.mp3';
print('A bg message just showed up : ${message.messageId}');
final android = AndroidInitializationSettings('@mipmap/ic_launcher');
final ios = IOSInitializationSettings(
requestSoundPermission: false,
requestBadgePermission: false,
requestAlertPermission: false,);
final settings = InitializationSettings(android: android,iOS: ios);
flutterLocalNotificationsPlugin.initialize(settings,);
if(message.data['title'].toString().toLowerCase()=="new request") {
sessionManager.getBadge().then((badge) {
if (badge != null) {
int x = badge + 1;
sessionManager.saveBadge(x);
print("notification number is " + x.toString());
}
else {
sessionManager.saveBadge(1);
}
});
}
flutterLocalNotificationsPlugin.show(
message.data.hashCode,
message.data['title'],
message.data['body'],
NotificationDetails(
android: AndroidNotificationDetails(
channel.id,
channel.name,
importance: Importance.high,
priority: Priority.high,
// sound: RawResourceAndroidNotificationSound(sound.split('.').first),
playSound: true,
icon: '@mipmap/ic_launcher',
),
));
/*NotificationApi.showNotification(

id: int.parse(channel.id));*/
}
Future<void> main() async{

await Firebase.initializeApp();
FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
await flutterLocalNotificationsPlugin

await FirebaseMessaging.instance.setForegroundNotificationPresentationOptions(

});
}
Future<String?> getToken() async{
String? token = await FirebaseMessaging.instance.getToken();
print("token is "+token!);
return token;
}
}
在yaml
firebase_core: ^1.12.0
firebase_messaging: ^11.2.6
dependency_overrides:
firebase_messaging_platform_interface: 3.1.6
编辑:从多个解决方案中,我尝试了最常见的解决方案,我在 initState
中使用了 onMessageOpenedApp
但它没有进入
FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
Navigator.push(context, MaterialPageRoute(builder: (context)=>DoneAndPaiedPagess(0)));
});
最佳答案
在您的代码中,您正在使用 flutter_local_notifications
插件,并且当您从 firebase 消息传递收到推送通知时,您正在创建本地通知。
由于通知不是由 firebase 消息传递创建的,因此您不会在 getInitialMessage
和 onMessageOpenedApp
中获得点击回调。
为了获得本地通知的点击回调,您可以在初始化 flutter_local_notifications
时传递回调函数
flutterLocalNotificationsPlugin.initialize(initializationSettings,
onSelectNotification: onSelectNotification);
void selectNotification(String payload) async {
if (payload != null) {
debugPrint('notification payload: $payload');
// Here you can check notification payload and redirect user to the respective screen
await Navigator.push(
context,
MaterialPageRoute<void>(builder: (context) => SecondScreen(payload)),
);
}
}
