flutter - 错误 : User must be valid and have a name

Question

我已经设置好一切以使用 Firebase Messaging。后台消息工作正常。但是对于前台消息，我遇到了以下错误:用户必须有效并且有一个名字。

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？!

我也遇到了这个问题，花了我一段时间。您需要提供摘要才能正常工作

试试这个

AwesomeNotifications().createNotification(
    content: NotificationContent(
      id: uniqueIdInt(),
      channelKey: 'basic_channel',
      title: notification!.title,
      body: notification.body,
      summary: 'summary' // Anything you want here
      notificationLayout: NotificationLayout.Messaging,
    ),
  );
