Hello Who?

A Flutter application that demonstrates the following concepts:

• An application-level state object
• that's also a ChangeNotifier
• a top-level ChangeNotifierProvider
• and a Consumer at the lowest level

Background

I needed a way to be able to show something at an earlier screen, but that would change depending on some user action in a later/deeper screen.

Along the way I also demonstrate writing a custom RoundedButton component, and a template for Flutter project organisation (/components, /models, /screens).
