Flutter & Firebase Auth 05 - Switch between login & home page + State initialization

In this video series on Flutter, I'll show you how to create a login and registration flow and Firebase integration, and extend it to build a full app.

In this video, I will cover:

  • Adding a root widget to control what UI to show depending on authentication state
  • How to initialise and update widgets state
  • Check whether the user is signed in on app startup
  • Adding callbacks to perform updates across widgets

Source code

Note: I'm using the iOS simulator, but you can open the Android emulator and run the same code.

This code was written with Flutter Beta 2, and is tested to work with Dart 2.
