 # Changelog
 
+## 0.4.0
+
+  * Works with Dart 2 (no longer supports Dart 1)
+  * Stronger Type info Required
+  * Breaking Changes: 
+    * `StoreProvider` now requires generic type info: `StoreProvider<AppState>`
+    * `new StoreProvider.of(context).store` is now `StoreProvider.of<AppState>(context)` 
+
 ## 0.3.5
 
   * Bugfix: `onInit` was not called before the initial ViewModel is constructed.

 A set of utilities that allow you to easily consume a [Redux](https://pub.dartlang.org/packages/redux) Store to build Flutter Widgets.
 
 This package is built to work with [Redux.dart](https://pub.dartlang.org/packages/redux).

 ## Redux Widgets 
 
   * `StoreProvider` - The base Widget. It will pass the given Redux Store to all descendants that request it.
   * `StoreBuilder` - A descendant Widget that gets the Store from a `StoreProvider` and passes it to a Widget `builder` function.
   * `StoreConnector` - A descendant Widget that gets the Store from the nearest `StoreProvider` ancestor, converts the `Store` into a `ViewModel` with the given `converter` function, and passes the `ViewModel` to a `builder` function. Any time the Store emits a change event, the Widget will automatically be rebuilt. No need to manage subscriptions!
 
+## Dart Support
+
+  * Dart 1: 0.3.x
+  * Dart 2: 0.4.0+. See the migration guide below!

 ## Examples

-### Purpose
+## Dart 2 Migration
+
+Dart 2 requires more strict typing (yay!), and gives us the option to make getting the Store from the StoreProvider more convenient!
+
+  1. Change `new StoreProvider(...)` to `StoreProvider<StateClass>(...)` in your Widget tree. 
+  2. Change `new StoreProvider.of(context).store` to `StoreProvider.of<StateClass>(context)` if you're directly fetching the `Store<AppState>` yourself from the `StoreProvider<AppState>`. No need to access the `store` field directly any more since Dart 2 can now infer the proper type with a static function :)  
+
+## Purpose
 
 One question that [reasonable people might ask](https://www.reddit.com/r/FlutterDev/comments/6vscdy/a_set_of_utilities_that_allow_you_to_easily/dm3ll7d/): Why do you need all of this if `StatefulWidget` exists?
