Error: User must be valid and have a name

Question

I've set up everything to work with Firebase Messaging. Background messages are working fine. But for foreground messages, I'm facing the following error: User must be valid and have a name.

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

It is throw in a call like this:

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

Any clue?!

Answer 1

I also had this problem and it took me a while. You need to provide a summary for it to work

Try this

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