    The User object has a metadata property, which has two properties: creationTime and lastSignInTime. When those are no more than a few milliseconds apart, the user was just created. If they’re further apart, the user was created in a previous session.

    FirebaseAuth User contains this data in metadata prop. I used the following chunk of code. You can change the number of seconds if you want.

    bool isNewUser(User user) {
  DateTime now = DateTime.now();
  DateTime cTime = user.metadata.creationTime;
  int longAgo = 15; // to check account creation under last 15 seconds
  return now.difference(cTime).inSeconds > longAgo;
}
