By default .then accepts dynamic parameter but if you wish to pass different parameter then you have change Function(dynamic) to Function(YOURTYPE) try below code:

static void getCurrentOnlineUserInformation()async{
  User user = _firebaseAuth.currentUser;
  String userid = user.uid;
  DatabaseReference reference = 
        FirebaseDatabase.instance.ref().child('userProfile');
         reference.child(userid).once().then(<DataSnapshot>(DataSnapshot dataSnapshot){
        }
      );
  }
