this error means you are being sent an empty response. there is something that you are missing in the request.
please ensure these points
checklist

  • header
  • token ( of receivers device)
  • fcm send url is valid
  • body is in the json format

logout and relogin on receiving device, make sure token is same and valid. in console you can print out if it is inside onlaunch ,onMessage or onResume if one of these methods is getting triggered on receiver app that means something is wrong with your implementation

actions: [
FlatButton(
