Doesn't support latest Firebase in iOS

[WillBeebe]

This compiles

dependencies:
  flutter:
    sdk: flutter
  firebase_core: ^0.5.0+1
  firebase_auth: ^0.18.0+2

This doesn't

dependencies:
  flutter:
    sdk: flutter
  firebase_core: ^0.5.0+1
  firebase_auth: ^0.18.0+2
  firebase_auth_ui: 1.0.1

The error is:

The packages used in this blog post are too old. I'm now following a promising guide that has fewer, generic dependencies.

It looks like that will work but I love this Library so I'm hoping to come back to it someday and rip out the workaround code. Cheers mate!
