Flutter & Firebase Authentication with Streams and StreamBuilder

This video is a continuation on my small series on how to build a login flow with Firebase.

In this video I show how to use a special stream called onAuthStateChanged, and use it to simplify our widgets logic.

This leads to a very elegant solution using StreamBuilder, which I highly recommend when using Firebase authentication.

This code was tested with Flutter stable 1.2.
