riverpod 0.13.1

A simple way to access state from anywhere in your application while robust and testable.

0.13.1

• Fixed a bug where overriding a FutureProvider with an error value could cause tests to fail (see https://github.com/rrousselGit/river_pod/issues/355)

0.13.0

• stable null-safety release
• ProviderObserver can now have a const constructor
• Added the mechanism for state-inspection using the Flutter devtool
• loosened the version constraints of freezed_annotation
• deprecated import 'riverpod/all.dart'. Now everything is available with riverpod/riverpod.dart.
• Fixed a but where listening to StreamProvider.last could result in a StateError (#217)

0.13.0-nullsafety.3

• deprecated import 'riverpod/all.dart'. Now everything is available with riverpod/riverpod.dart.

0.13.0-nullsafety.1

• Fixed a but where listening to StreamProvider.last could result in a StateError (#217)

0.13.0-nullsafety.0

Migrated to null-safety

0.12.2

• Exported AutoDisposeProviderReference

0.12.1

• Fixed an remaining memory leak related to StreamProvider (see also https://github.com/rrousselGit/river_pod/issues/193)

0.12.0

• Breaking FutureProvider and StreamProvider no-longer supports null as a valid value.
• Fixed a memory leak with StreamProvider (see also https://github.com/rrousselGit/river_pod/issues/193)

0.11.2

• Fixed a bug where providers (usually ScopedProviders) did not dispose correctly (see also https://github.com/rrousselGit/river_pod/issues/154).

0.11.0

• package:riverpod/riverpod.dart now exports StateNotifier
• Marked the providers with @sealed so that the IDE warns against implementing/subclassing providers.
• Fix mistakes in AsyncValue.guard's documentation (thanks @mono0926)
• Loosened the version constraints of freezed_annotation to support 0.12.0

0.10.0

• Fixed a bug where the state of a provider may be disposed when it shouldn't be disposed.

• Added a way to import the implementation class of providers with modifiers, such as AutoDisposeProvider.

  This is useful if you want to use Riverpod with the lint always_specify_types:

  import 'package:riverpod/all.dart';
  
  final AutoDisposeStateProvider<int> counter = StateProvider.autoDispose<int>((ProviderReference ref) {
    return 0;
  });
  

  If you do not use this lint, prefer using the default import instead, to not pollute your auto-complete.

0.8.0

• Renamed ProviderContainer.debugProviderStates to ProviderContainer.debugProviderElements
• Fixed a bug where updating ProviderScope.overrides may cause an exception for no reason (see https://github.com/rrousselGit/river_pod/issues/107)

0.7.0

• ref.watch on non ".autoDispose" providers can no-longer read ".autoDispose" providers.

  For more info, see http://riverpod.dev/docs/concepts/modifiers/auto_dispose#the-argument-type-autodisposeprovider-cant-be-assigned-to-the-parameter-type-alwaysaliveproviderbase

• ScopedProvider now accepts null as a function:

  final example = ScopedProvider<int>(null);
  

  Which is equivalent to:

  final example = ScopedProvider<int>((watch) => throw UnimplementedError(''));
  

• Fixed a bug where context.refresh may not work properly if the widget tree contains multiple ProviderScope.

0.6.1

• Fixed a bug where when disposing ProviderContainer, providers may be disposed in an incorrect order.
• Improved the performances of reading providers by 25%

0.6.0

• Merged Computed and Provider. Now, all providers have the ability to rebuild their state when one of the object they listen changed.

  To migrate, change:

  final provider = Provider(...);
  final example = Computed((watch) {
    final value = watch(provider);
    return value;
  });
  

  into:

  final provider = Provider(...);
  final example = Provider((ref) {
    final value = ref.watch(provider);
    return value;
  });
  

• Computed (now Provider) no-longer deeply compare collections to avoid rebuilds. Comparing the content of lists is quite expensive and actually rarely useful. Now, a simple == comparison is used.

• Renamed ProviderStateOwner to ProviderContainer

• Renamed ProviderStateOwnerObserver to ProviderObserver

• It is no-longer possible to override a provider anywhere in the widget tree. Providers can only be overriden in the top-most ProviderContainer.

• Providers can now read values which may change over time using ref.read and ref.watch. When using ref.watch, if the value obtained changes, this will cause the provider to re-create its state.

• It is no-longer possible to add ProviderObserver anywhere in the widget tree. They can be added only on the top-most ProviderContainer.

• Added ProviderContainer.refresh(provider). This method allows forcing the refresh of a provider, which can be useful for things like "retry on error" or "pull to refresh".

• ref.read(StreamProvider<T>) no-longer returns a Stream<T> but an AsyncValue<T> Before:

  final streamProvider = StreamProvider<T>(...);
  final example = Provider((ref) {
    Stream<T> stream = ref.read(streamProvider);
  });
  

  After:

  final streamProvider = StreamProvider<T>(...);
  final example = Provider((ref) {
    Stream<T> stream = ref.watch(streamProvider.steam);
  });
  

• ref.read(FutureProvider<T>) no-longer returns a Future<T> but an AsyncValue<T>

  Before:

  final futureProvider = FutureProvider<T>(...);
  final example = Provider((ref) {
    Future<T> future = ref.read(futureProvider);
  });
  

  After:

  final futureProvider = FutureProvider<T>(...);
  final example = Provider((ref) {
    Future<T> future = ref.watch(futureProvider.future);
  });
  

• Removed ref.dependOn. You can now use ref.read/ref.watch to acheive the same effect.

  Before:

  final streamProvider = StreamProvider<T>(...);
  final example = Provider((ref) {
    Future<T> last = ref.dependOn(streamProvider).last;
  });
  

  After:

  final streamProvider = StreamProvider<T>(...);
  final example = Provider((ref) {
    Future<T> last = ref.watch(streamProvider.last);
  });
  

• Provider.readOwner(ProviderStateOwner) is changed into ProviderContainer.read(Provider)

• Provider.watchOwner(ProviderStateOwner, (value) {}) is changed into:

  ProviderContainer container;
  final provider = Provider((ref) => 0);
  
  final subscription = container.listen(
    provider,
    mayHaveChanged: (sub) {},
    didChange: (sub) {}.
  );
  
  subscription.close();
  

• MyProvider.family.autoDispose now correctly free both the arguments and the associated providers from memory when the provider is no-longer listened.

• Added ScopedProvider, a new kind of provider that can be overriden anywhere in the widget tree. Normal providers cannot read a ScopedProvider.

0.5.1

• Fixed the documentation of StateNotifierProvider incorrectly showing the documentation of StreamProvider.
• Improve the documentation of StateProvider.

0.5.0

• Changed ComputedFamily into Computed.family
• Added [AsyncValue.guard](https://pub.dev/documentation/riverpod/latest/riverpod/AsyncValue/guard.html to simplify transforming a Future into an AsyncValue.
• Improved the documentation of the different providers

0.4.0

Changed the syntax of "AutoDispose*" and "*Family" to use a syntax similar to named constructors instead.

Before:

final myProvider = AutoDisposeStateNotifierProviderFamily<MyStateNotifier, int>((ref, id) {
  return MyStateNotifier(id: id);
});

After:

final myProvider = StateNotifierProvider.autoDispose.family<MyStateNotifier, int>((ref, id) {
  return MyStateNotifier(id: id);
});

The behavior is the same. Only the syntax changed.

0.3.0

• Added AsyncValue.whenData, syntax sugar for AsyncValue.when to handle only the data case and do nothing for the error/loading cases.

• Fixed a bug that caused [Computed] to crash if it stopped being listened then was listened again.

0.2.1

• Computed now correctly unsubscribe to a provider when their function stops using a provider.

0.2.0

• ref.read is renamed as ref.dependOn
• Deprecated ref.dependOn(streamProvider).stream and ref.dependOn(futureProvider).future in favor of a universal ref.dependOn(provider).value.
• added ref.read(provider), syntax sugar for ref.dependOn(provider).value.

0.1.0
