当我收到来自 firebase 的通知时,我需要显示自定义对话框。但我不知道如何从通知负载中获取我的数据
我试过下面的代码,但它是机器人为我工作
Future<void> _handleNotification(
Map<dynamic, dynamic> message, bool dialog) async {
final dynamic data = message['data'] ?? message;
final dynamic notification = message['notification']['body'] ?? message;
final String itemId = data['body'];
debugPrint("DATA ->> $data");
debugPrint("notification ->> $notification");
message.forEach((k, v) => debugPrint("${k} - ${v}"));
}

这是我在控制台中的有效载荷
flutter: 通知消息 {gcm.message_id: 1578573493122232, id: 30, google.cae: 1, type: test, aps: {alert: {title: notication title, body: Message of Push notification}, sound: 1}}
任何机构都可以帮助从通知负载中获取数据吗?
最后我可以自己解决这个问题
如果您想从通知负载中获取数据,那么您需要"data"在消息的 -field内发送您的数据。
示例代码从
"data"消息的 -field读取数据。
Future<void> _handleNotification(
Map<dynamic, dynamic> message, bool dialog) async {
var data = message['data'] ?? message;
String notificationTitle = data['YOUR_KEY']; // here you need to replace YOUR_KEY with the actual key that you are sending in notification **`"data"`** -field of the message.
String notificationMessage = data['YOUR_KEY'];// here you need to replace YOUR_KEY with the actual key that you are sending in notification **`"data"`** -field of the message.
// now show the Dialog
Utils().showMessageDialog(context, notificationTitle,notificationMessage);
}
