Description

I am currently experiencing a problem when I receive the remoteMessage body in FirebaseMessaging.onMessage.listen, it comes with empty or null information, this is strange since on some devices it comes without problem but on others it fails but sometimes on those that fail the information arrives correctly, I have not been able to find a pattern but in the logs of my server where the notification is sent this sent information does not have any type of error, this has happened since I updated to version 15.1.4 of flutter_messaging

{
  senderId: null,
  category: null,
  collapseKey: null,
  contentAvailable: false,
  data: {},
  from: null,
  messageId: null,
  messageType: null,
  mutableContent: false,
  notification: null,
  sentTime: 0,
  threadId: null,
  ttl: 0
}

Reproducing the issue

I have no idea how to replicate it, sometimes the data key has information without problems and sometimes it arrives empty

Hi @gvillegasc, thanks for the report. Unfortunately, this is beyond flutterfire's control since it appears your issue is device-specific and also without any concrete way to reproduce.
