# 3.0.0

## breaking (see the readme for migration steps):

- `Provider` now throws if used with a `Listenable`/`Stream`. This can be disabled by setting
  `Provider.debugCheckInvalidValueType` to `null`.
- The default constructor of `StreamProvider` has now builds a `Stream`
  instead of `StreamController`. The previous behavior has been moved to `StreamProvider.controller`.
- All `XXProvider.value` constructors now use `value` as parameter name.
- Added `FutureProvider`, which takes a future and updates dependents when the future completes.
- Providers can no longer be instantiated using `const` constructors.

## non-breaking:

- Added `ProxyProvider`, `ListenableProxyProvider`, and `ChangeNotifierProxyProvider`.
  These providers allows building values that depends on other providers,
  without loosing reactivity or manually handling the state.
- Added `DelegateWidget` and a few related classes to help building custom providers.
- Exposed the internal generic `InheritedWidget` to help building custom providers.

# 2.0.1

- fix a bug where `ListenableProvider.value`/`ChangeNotifierProvider.value`
  /`StreamProvider.value`/`ValueListenableProvider.value` subscribed/unsubscribed
  to their respective object too often
- fix a bug where `ListenableProvider.value`/`ChangeNotifierProvider.value` may
  rebuild too often or skip some.

# 2.0.0

- `Consumer` now takes an optional `child` argument for optimization purposes.
- merged `Provider` and `StatefulProvider`
- added a "builder" constructor to `ValueListenableProvider`
- normalized providers constructors such that the default constructor is a "builder",
  and offer a `value` named constructor.

# 1.6.1

- `Provider.of<T>` now crashes with a `ProviderNotFoundException` when no `Provider<T>`
  are found in the ancestors of the context used.

# 1.6.0

- new: `ChangeNotifierProvider`, similar to scoped_model that exposes `ChangeNotifer` subclass and
  rebuilds dependents only when `notifyListeners` is called.
- new: `ValueListenableProvider`, a provider that rebuilds whenever the value passed
  to a `ValueNotifier` change.

# 1.5.0

- new: Add `Consumer` with up to 6 parameters.
- new: `MultiProvider`, a provider that makes a tree of provider more readable
- new: `StreamProvider`, a stream that exposes to its descendants the current value of a `Stream`.

# 1.4.0

- Reintroduced `StatefulProvider` with a modified prototype.
  The second argument of `valueBuilder` and `didChangeDependencies` have been removed.
  And `valueBuilder` is now called only once for the whole life-cycle of `StatefulProvider`.

# 1.3.0

- Added `Consumer`, useful when we need to both expose and consume a value simultaneously.

# 1.2.0

- Added: `HookProvider`, a `Provider` that creates its value from a `Hook`.
- Deprecated `StatefulProvider`. Either make a `StatefulWidget` or use `HookProvider`.
- Integrated the widget inspector, so that `Provider` widget shows the current value.

# 1.1.1

- add `didChangeDependencies` callback to allow updating the value based on an `InheritedWidget`
- add `updateShouldNotify` method to both `Provider` and `StatefulProvider`

# 1.1.0

- `onDispose` has been added to `StatefulProvider`
- `BuildContext` is now passed to `valueBuilder` callback
