Shrine

A sample shopping app that uses Material Component widgets in its UI and scoped_model to manage the state of its shopping cart.

Goals

• Show how to customize Flutter's Material Component widgets to produce a unique design for an app.
• Show how to use scoped_model to manage an app's state and access it across different routes and in different widgets.

This is a modified version of the app featured in Flutter's Material codelabs.

The important bits

/model/app_state_model.dart

The model object representing the state of the app. It holds the available products as well as what's in the shopping cart.

/supplemental

A bunch of widgets that customize Material to produce the look and feel of the app.

shopping_cart.dart

The shopping cart widgets. They access the app state model via ScopedModelDescendant, display the contents of the shopping cart, and allow the user to edit them.
