firebase - cloud_firestore 0.14.0 how to use the data method

Question

I updated to cloud_firestore 0.14.0

There's a few break changes:

BREAKING: The get data getter is now a data() method instead.

Before the update this is how I used the getter data

Before:

Future<String> getUsernameFromUserId(String userId) async {
        return (await _userFirestoreCollection.document(userId).get()).data['screenName'];
    }

This is how I use data now.. But doesn't seem to be working... Now:

Future<String> getUsernameFromUserId(String userId) async {
            return (await _userFirestoreCollection.document(userId).get()).data()['screenName'];
        }
