+# provider_shopper
+
+A Flutter sample app that shows a state management approach using the [Provider][] package.
+This is the app discussed in the [Simple app state management][simple] section of
+[flutter.dev][].
+
+
+
+[Provider]: https://pub.dev/packages/provider
+[simple]: https://flutter.dev/docs/development/data-and-backend/state-mgmt/simple
+[flutter.dev]: https://flutter.dev/
+
+## Goals for this sample
+
+* Show simple use of `Provider` for providing an immutable value to a subtree
+* Illustrate a simple state management approach using the ChangeNotifier class
+* Show use of `ProxyProvider` for provided objects that depend on other provided objects
+
+## The important bits
+
+### `lib/main.dart`
+
+Here the app sets up objects it needs to track state: a catalog and a shopping cart. It builds
+a `MultiProvider` to provide both objects at once to widgets further down the tree.
+
+The `CartModel` instance is provided using a `ChangeNotifierProxyProvider`, which combines
+two types of functionality:
+
+1. It will automatically subscribe to changes in `CartModel` (if you only want this functionality
+ simply use `ChangeNotifierProvider`).
+2. It takes the value of a previously provided object (in this case, `CatalogModel`, provided
+ just above), and uses it to build the value of `CartModel` (if you only want
+ _this_ functionality, simply use `ProxyProvider`).
+
+### `lib/models/*`
+
+This directory contains the model classes that are provided in `main.dart`. These classes
+represent the app state.
+
+### `lib/screens/*`
+
+This directory contains widgets used to construct the two screens of the app: the catalog and
+the cart. These widgets have access to the current state of both the catalog and the cart
+via `Provider.of`.
+
+## Questions/issues
+
+If you have a general question about Provider, the best places to go are:
+
+* [Provider documentation](https://pub.dev/documentation/provider/latest/)
+* [StackOverflow](https://stackoverflow.com/questions/tagged/flutter)
+
+If you run into an issue with the sample itself, please file an issue
+in the [main Flutter repo](https://github.com/flutter/flutter/issues).
