[英]Flutter - Call Firebase onMessage method when the app is in background
当应用程序在 flutter 的后台时,问题与此处的 Call onMessage 方法相同,我正在关注该线程,但由于没有响应,我再次问这个问题。
我已将我的 Flutter 应用程序与Firebase 消息连接,当我的应用程序位于前台时,我使用Flutter 本地通知插件收到通知。 但是当我的应用程序处于后台时,我无法收到任何通知
以下是我的代码:
// FIREBASE CONFIGURATION & HANDLING
_firebaseMessaging.configure(
onMessage: (Map<String, dynamic> message) async {
debugPrint("onMessage: $message");
final notification = message['data']['notification'];
Map responseBody = convert.jsonDecode(notification);
_showNotification(
icon: responseBody['icon'],
title: responseBody['title'],
body: responseBody['body'],
);
setState(() {});
},
);
// DISPLAY NOTIFICATION - HEADS UP
Future<void> _showNotification({String icon, String title, String body}) async {
var androidPlatformChannelSpecifics = AndroidNotificationDetails(
'your channel id',
'your channel name',
'your channel description',
importance: Importance.Max,
priority: Priority.High,
ticker: 'ticker',
);
var iOSPlatformChannelSpecifics = IOSNotificationDetails();
var platformChannelSpecifics = NotificationDetails(
androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.show(
0,
title,
body,
platformChannelSpecifics,
);
}
有人可以指导我如何在我的应用程序处于后台时接收通知
解决!!
问题在于 curl 调用的格式。 根据此处给出的说明
改变了这个:
{
"data": {
"notification": {
"title": "Notification Title",
"body": "Notification Body",
},
"click_action": "FLUTTER_NOTIFICATION_CLICK"
},
"to": "YOUR_DEVICE_TOKEN"
}
对此:
{
"data": {
"click_action": "FLUTTER_NOTIFICATION_CLICK",
"id": "1",
"status": "done",
},
"notification": {
"body": "Notification Body",
"title": "Notification Title"
},
"priority": "high",
"to": "YOUR_DEVICE_TOKEN"
}
