我更新了 firebase_messaging,由于 FirebaseMessaging.configure()
被弃用了,所以我必须更改我的代码。现在当我接收到通知并单击通知时,它不会打开另一个屏幕。
这是我实现通知的方式:
Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
await Firebase.initializeApp();
print('Handling a background message ${message.messageId}');
}
const AndroidNotificationChannel channel = AndroidNotificationChannel(
'high_importance_channel', // id
'High Importance Notifications', // title
'This channel is used for important notifications.', // description
importance: Importance.high,
);
final FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin =
FlutterLocalNotificationsPlugin();
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
runApp(MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key key}) : super(key: key);
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'e-Rădăuți',
debugShowCheckedModeBanner: false,
initialRoute: '/',
routes: {
'/': (_) => MenuScreen(),
'/events': (BuildContext context) => EventsScreen(),
},
);
}
}
class MenuScreen extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}
Widget build(BuildContext context) {
return Scaffold();
}
@override
void initState() {
super.initState();
FirebaseMessaging.onMessage.listen((RemoteMessage message) {
RemoteNotification notification = message.notification;
AndroidNotification android = message.notification?.android;
if (notification != null && android != null) {
flutterLocalNotificationsPlugin.show(
notification.hashCode,
notification.title,
notification.body,
NotificationDetails(
android: AndroidNotificationDetails(
channel.id,
channel.name,
channel.description,
icon: 'launch_background',
),
));
}
});
FirebaseMessaging.onMessageOpenedApp.listen((RemoteMessage message) {
debugPrint('A new onMessageOpenedApp event was published!');
Navigator.pushNamed(context, '/events');
});
}
}
但是当我点击通知时,
.onMessageOpenedApp
没有被调用,因为在我的控制台(VSCode)中没有看到 debugPrint
消息,并且我收到了以下错误:D/FLTFireMsgReceiver( 4799): broadcast received for message
W/civic.e_radaut( 4799): Accessing hidden method Landroid/os/WorkSource;->add(I)Z (greylist,test-api, reflection, allowed)

我使用 click_action: FLUTTER_NOTIFICATION_CLICK
在firebase中发送了我的通知,在我的清单文件中添加了以下内容:
<intent-filter>
<action android:name="FLUTTER_NOTIFICATION_CLICK" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
我的 firebase_messaging
版本是 ^8.0.0-dev.15
因此,我不知道我漏掉了什么或者为什么它没有起作用。如果您需要更多细节,请随时提问。
.onMessage.listen',因为应用程序已经打开并在前台,所以实际上不会打开应用程序,因此不会调用
FirebaseMessaging.onMessageOpenedApp.listen,而是调用
FirebaseMessaging.onMessage.listen`。我不确定这是否有效,因为我没有在应用程序在前台时实现回调。如果您没有找到解决方案,请给我发消息,我将尝试在我的代码中实现并查看它是否有效。 - t3nsa.onMessage
中添加了一个debugPrint();
,如果应用程序在前台时它会被触发,但当我点击它时不会触发,只有在收到通知时才会触发。如果我找到解决方案,我会告诉你。 - t3nsa
