Problem getting user UID in Fuse Firebase Authentication Example

Hey there!
I have been using the Firebase Integration as suggested for Google and Facebook Authentication

I get the following when the user logs in;;

How do I get the users UID in the following function?

FirebaseUser.signedInStateChanged = function() {
    if (FirebaseUser.isSignedIn)


if you take a look at the Authentication implementation in the source code of the library you are using, you will find that there is no method implemented for getting a user id.

Since this is an open-source effort, you are welcome to fork the repo and implement the missing functionality yourself. Or if you’re not up to the task, please register a ticket on that repo.
