# Shrine
|
||
|
|
|
||
|
|
A sample shopping app that uses Material Component widgets in its UI and
|
||
|
|
[`scoped_model`](https://pub.dartlang.org/packages/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](https://codelabs.developers.google.com/?cat=Flutter).
|
||
|
|
|
||
|
|
## 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.

||
