firebase - 如何获取Firebase通知数据？

Question

当我在应用程序中时，可以在onMessage中获取Firebase消息，如下所示:

{data: {}, notification: {body: how are you , title: hi}}

我在 initState中的代码:

    firebaseMessaging.configure(

    onLaunch: (Map<String,dynamic> msg){
      print(" onLaunch called");
      print(msg);
    },
    onResume: (Map<String,dynamic> msg){
      print(" onResume called");
      print(msg);

    },
    onMessage: (Map<String,dynamic> msg){
      print(" onMessage called");
      print(msg);
      setState(() {
        sms=msg['notification']['body'];
      });
    },


    );
     firebaseMessaging.requestNotificationPermissions(
      const IosNotificationSettings(
          sound: true,
          alert: true,
          badge: true
      )
    );
      firebaseMessaging.onIosSettingsRegistered.listen((IosNotificationSettings setting){
       print("ios setting registed");
    });
      firebaseMessaging.getToken().then((token){
       update(token);
    });
    }
     update(String token){
       print(token);
        setState(() {
         textValue=token;
     });

我想在后台或关闭应用程序时收到Firebase消息，
我该怎么办？

您只需要在Firebase Messaging软件包的Receiving Message部分中进行描述即可。

仅当用户单击通知时，onResume和onLaunch方法的方法才触发
