I made an app that authenticates in GitHub with the firebase, it takes the data and logs but when I go in FirebaseAuth.getInstance (). getCurrentUser () FirebaseUser does not have a method that returns a login. I need to get some information from this logged in user that is only available with the login and not with the email. It takes the email, username but not login.
To access this url later link {user} esse {user} is the login !!!
