我已经设置了与 Firebase Messaging 配合使用的所有内容。后台消息工作正常。但对于前台消息，我面临以下错误：用户必须有效并且有名称。

W/System.err(15714): java.lang.RuntimeException: User must be valid and have a name.

它是这样调用的：

     AwesomeNotifications().createNotification(
        content: NotificationContent(
          id: uniqueIdInt(),
          channelKey: 'basic_channel',
          title: notification!.title,
          body: notification.body,
          notificationLayout: NotificationLayout.Messaging,
        ),
      );

有什么线索吗？
