Here is my attempt:

Future<FirebaseUser> user =FirebaseAuth.instance.currentUser();
DocumentReference ref =Firestore.instance.collection('users').document(user.uid);

Please help

You need to await to get the FirebaseUser before you can access the id. I created a simple function below demonstrating this for you. 

Future<DocumentReference> getUserDoc() async {
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final Firestore _firestore = Firestore.instance;

  FirebaseUser user = await _auth.currentUser();
  DocumentReference ref = _firestore.collection('users').document(user.uid);
  return ref;
}
