firebase - Flutter Firestore How To Listen For Changes To ONE Document

Question

I just want to get notified whenever ONE document is changed or updated. Every example of getting updates is always using collections. I tried to implement that with only using one document and it never gets any updates. Here is what I have right now that doesn't work:

@override
Widget build(BuildContext context) {
StreamBuilder<DocumentSnapshot>(
    stream: Firestore.instance
        .collection("users")
        .document(widget.uid)
        .snapshots(),
    builder:
        (BuildContext context, AsyncSnapshot<DocumentSnapshot> snapshot) {
      user = snapshot.data.data as User;
    });

I've debugged this 100 times and it never gets to the "builder:" section. And this is not a problem with the document reference by the way. What am I doing wrong here?
