Question

我试图像这样在我的flutter应用程序中获取消息数据：

  firebaseMessaging.requestNotificationPermissions(
      const IosNotificationSettings(sound: true, alert: true, badge: true));
  firebaseMessaging.configure(onLaunch: (Map<String, dynamic> message) {
    print(" onLaunch called!" + message.toString());
  }, onMessage: (Map<String, dynamic> message) {
    print(" onMessage called!" + message.toString());
  }, onResume: (Map<String, dynamic> message) {
    print(" onResume called!" + message.toString());
  });

  firebaseMessaging.onIosSettingsRegistered.listen((iosNotificationSettings) {
    print("============ IOS settings registered!");
  });

设备正在接收通知，但我无法访问该通知。通知json：

{
    "notification": {
      "body": "body",
      "title": "title",
      "sound": "default"
    },
    "priority": "high",
    "data": {
      "click_action": "FLUTTER_NOTIFICATION_CLICK"
    },
    "registration_ids": ["a token"]
  }

每当我收到通知时，都会在控制台中收到此消息：

W/FirebaseMessaging(22018): Error while parsing timestamp in GCM event
W/FirebaseMessaging(22018): java.lang.NumberFormatException: null

我如何获取消息以及随该通知发送的数据？

Answer 1

print(message['body']);

尝试打印这样的消息并查看。

Answer 2

尝试消息['title']。toString（） message ['body']。toString（）

为什么我的通知数据扑朔迷离？
