+# shared_preferences
+
+Wraps NSUserDefaults (on iOS) and SharedPreferences (on Android), providing
+a persistent store for simple data. Data is persisted to disk automatically
+and asynchronously.
+
+## Usage
+To use this plugin, add shared_preferences as a [dependency in your pubspec.yaml file](https://flutter.io/platform-plugins/).
+
+### Example
+
+``` dart
+import 'package:flutter/material.dart';
+import 'package:shared_preferences/shared_preferences.dart';
+
+void main() {
+  runApp(new MaterialApp(
+    home: new Scaffold(
+      body: new Center(
+      child: new RaisedButton(
+        onPressed: _incrementCounter,
+        child: new Text('Increment Counter'),
+        ),
+      ),
+    ),
+  ));
+}
+
+_incrementCounter() async {
+  SharedPreferences prefs = await SharedPreferences.getInstance();
+  int counter = (prefs.getInt('counter') ?? 0) + 1;
+  print('Pressed $counter times.');
+  prefs.setInt('counter', counter);
+}
+```

+
+dependencies:
+  flutter:
+    sdk: flutter

+    path: ../
+
+# For information on the generic Dart part of this file, see the
+# following page: https://www.dartlang.org/tools/pub/pubspec
+
+# The following section is specific to Flutter.
+flutter:
+
+  # The following line ensures that the Material Icons font is
+  # included with your application, so that you can use the icons in
+  # the Icons class.
+  uses-material-design: true
+
+  # To add assets to your application, add an assets section here, in
+  # this "flutter" section, as in:
+  # assets:
+  #  - images/a_dot_burr.jpeg
+  #  - images/a_dot_ham.jpeg
+
+  # To add assets from package dependencies, first ensure the asset
+  # is in the lib/ directory of the dependency. Then,
+  # refer to the asset with a path prefixed with
+  # `packages/PACKAGE_NAME/`. Note: the `lib/` is implied, do not
+  # include `lib/` in the asset path.
+  #
+  # Here is an example:
+  #
+  # assets:
+  #  - packages/PACKAGE_NAME/path/to/asset
+
+  # To add custom fonts to your application, add a fonts section here,
+  # in this "flutter" section. Each entry in this list should have a
+  # "family" key with the font family name, and a "fonts" key with a
+  # list giving the asset and other descriptors for the font. For
+  # example:
+  # fonts:
+  #   - family: Schyler
+  #     fonts:
+  #       - asset: fonts/Schyler-Regular.ttf
+  #       - asset: fonts/Schyler-Italic.ttf
+  #         style: italic
+  #   - family: Trajan Pro
+  #     fonts:
+  #       - asset: fonts/TrajanPro.ttf
+  #       - asset: fonts/TrajanPro_Bold.ttf
+  #         weight: 700
