riverpod 2.0.0-dev.6 riverpod: ^2.0.0-dev.6 copied to clipboard
A simple way to access state from anywhere in your application while robust and testable.
2.0.0-dev.6 #
- Added
AsyncValue.valueOrNull
to obtain the value while ignoring potential errors. - Fixed an issue where
AsyncValue.value
did not throw if there is an error. - Fix families not applying cacheTime/disposeDelay
- Fixed a bug where an exception may be thrown asynchronously after a
KeepAliveLink
is cancelled.
2.0.0-dev.5 #
- Fixed a bug where emitting an
AsyncData
after anAsyncError
leads toAsyncValue.hasError
to be true
2.0.0-dev.4 #
-
Added
ref.listenSelf
, for subscribing to changes of a provider within that provider. That can be useful for logging purposes or storing the state of a provider in a DB. -
Added
disposeDelay
to allautoDispose
providers and toProviderContainer
/ProviderScope
. This configures the amount of time before a provider is disposed when it is not listened. -
Added
container.invalidate(provider)
/ref.invalidate(provider)
andref.invalidateSelf()
. These are similar toref.refresh
methods, but do not immediately rebuild the provider.These methods are safer than
ref.refresh
as they can avoid a provider rebuilding twice in a quick succession. -
The duration passed to
cacheTime
now represents the minimum amount of time after the latest change of a provider, instead of the first time a provider built. -
Fixed an issue where providers were incorrectly allowed to depend on themselves, breaking
autoDispose
in the process. -
Fixed a memory leak when using
StateProvider.autoDispose
's.state
-
Fix
ProviderObserver.didDisposeProvider
not executing on provider refresh.
2.0.0-dev.3 #
When calling ref.listen
on a provider, this provider will now properly
rebuild if one of its dependency had changed.
2.0.0-dev.2 #
-
Deprecated
ref.maintainState=
in favor of a newly addedref.keepAlive()
. This newref.keepAlive()
function is similar tomaintainState
but better handles cases where we have multiple logics that want to keep the state of a provider alive for some period of time. -
Removed the deprecated
ProviderReference
. -
Added
ProviderContainer.cacheTime
andMyProvider.autoDispose(..., cacheTime: duration)
.cacheTime
is used to keep anautoDispose
provider alive for at least a minimum amount of time before it gets disposed if not listened. -
Added
ref.onAddListener
,ref.onRemoveListener
,ref.onCancel
andref.onResume
. All of which allow performing side-effects when providers are listened or stop being listened.
2.0.0-dev.1 #
-
Now requires Dart 2.16
-
Breaking Providers no-longer throw a
ProviderException
if an exception was thrown while building their value.
Instead, they will rethrow the thrown exception and its stacktrace. -
Removed
AsyncValue
'sisError
/isData
-
Added new functionalities to
AsyncValue
:hasError
,hasData
,copyWithPrevious
-
Added
provider.selectAsync
, which allows to both await an async value while also filtering rebuilds. -
When a provider emits an
AsyncError
followed by anAsyncData
, theAsyncData
emitted will now contain the latest error/stackTrace too. -
Fixed a cast error when overriding a provider with a more specific provider type (#1100)
-
Fixed a bug where
onDispose
listeners could be executed twice under certain conditions when usingautoDispose
.
2.0.0-dev.0 #
-
Breaking After a provider has emitted an
AsyncValue.data
orAsyncValue.error
, that provider will no longer emit anAsyncValue.loading
.
Instead, it will re-emit the latest value, but with the propertyAsyncValue.isRefreshing
to true.This allows the UI to keep showing the previous data/error when a provider is being refreshed.
-
Adding
isLoading
,isError
,isData
andasError
toAsyncValue
. Those getters allow interacting withAsyncValue
without having to rely on pattern matching. -
Fixed an issue where refreshing a
provider.future
/provider.stream
did work properly -
Fixed false positive with
ref.watch
asserts
1.0.3 #
Removed an assert preventing from overriding the same provider/family
multiple times on a ProviderScope
/ProviderContainer
.
1.0.2 #
Fixed a null exception on web
1.0.1 #
Improved the performance of the assert which verifies that providers properly
respect their dependencies
variable.
1.0.0 #
Riverpod is now stable!
General changes #
-
Breaking:
ProviderContainer.debugProviderValues
andProviderContainer.debugProviderElements
are removed. You can now instead useProviderContainer.getAllProviderElements
. -
Increased minimum SDK version to 2.14.0
-
Breaking The return value when reading a
StateProvider
changed. Before, doingref.read(someStateProvider)
would return theStateController
instance.
Now, this will only return the state of theStateController
.
This new behaviour matchesStateNotifierProvider
.For a simple migration, the old behavior is available by writing
ref.read(someStateProvider.state)
. -
Added
ref.listen
for triggering actions inside providers/widgets when a provider changes.It can be used to listen to another provider without recreating the provider state:
final counterProvider = StateNotifierProvider<Counter, int>(...); final anotherProvider = Provider<T>((ref) { ref.listen<int>(counterProvider, (previous, count) { print('counter changed from $previous to $count'); }); });
Alternatively, it can be used by widgets to show modals/dialogs:
final counterProvider = StateNotifierProvider<Counter, int>(...); class Example extends ConsumerWidget { @override Widget build(BuildContext context, WidgetRef ref) { ref.listen<int>(counterProvider, (previous, count) { showDialog(...); }); } }
-
It is now possible to "await" all providers that emit an
AsyncValue
(previously limited toFutureProvider
/StreamProvider
). This includes cases where aStateNotifierProvider
exposes anAsyncValue
:class MyAsyncStateNotifier extends StateNotifier<AsyncValue<MyState>> { MyAsyncStateNotifier(): super(AsyncValue.loading()) { // TODO fetch some data and update the state when it is obtained } } final myAsyncStateNotifierProvider = StateNotifierProvider<MyAsyncStateNotifier, AsyncValue<MyState>>((ref) { return MyAsyncStateNotifier(); }); final someFutureProvider = FutureProvider((ref) async { MyState myState = await ref.watch(myAsyncStateNotifierProvider.future); });
-
Deprecated
StreamProvider.last
in favor ofStreamProvider.future
. -
StreamProvider.future
,StreamProvider.stream
andFutureProvider.future
now expose a future/stream that is independent from how many times the associated provider "rebuilt":- if a
StreamProvider
rebuild before its stream emitted any value,StreamProvider.future
will resolve with the first value of the new stream instead. - if a
FutureProvider
rebuild before its future completes,FutureProvider.future
will resolve with the result of the new future instead.
- if a
-
You can now override any provider with any other provider, as long as the value that they expose matches. For example, it is possible to override a
StreamProvider<Model>
with aProvider<AsyncValue<Model>>
. -
ref.onDispose
now calls the dispose function as soon as one of the provider's dependencies is known to have changed -
Providers can now call
ref.refresh
to refresh a provider, instead of having to doref.container.refresh
. -
Providers no longer wait until their next read to recompute their state if one of their dependencies changed and they have listeners.
-
Added
ProviderContainer.pump
, a utility to easily "await" until providers notify their listeners or are disposed. -
fixed an issue when using both
family
andautoDispose
that could lead to an inconsistent state
Unified the syntax for interacting with providers #
-
ProviderReference
is deprecated in favor ofRef
. -
ref.watch
now supportsmyProvider.select((value) => ...)
. This allows filtering rebuilds:final userProvider = StateNotifierProvider<UserController, User>(...); final anotherProvider = Provider((ref) { // With this syntax, the Consumer will not rebuild if `userProvider` // emits a new User but its "name" didn't change. bool userName = ref.watch(userProvider.select((user) => user.name)); });
-
Breaking:
ProviderObserver.didUpdateProvider
now receives both the previous and new value. -
Breaking:
ProviderObserver.mayHaveChanged
is removed. -
Breaking:
Family.overrideWithProvider
now must create a provider:final family = Provider.family<State, Arg>(...); family.overrideWithProvider( (Arg arg) => Provider<State>((ref) => ...) );
-
All providers now receive a custom subclass of
ProviderRefBase
as a parameter:Provider<T>((ProviderRef<T> ref) {...}); FutureProvider<T>((FutureProviderRef<T> ref) {...}); StateProvider<T>((StateProviderRef<T> ref) {...});
That allows providers to implement features that is not shared with other providers.
-
Provider
,FutureProvider
andStreamProvider
'sref
now have astate
property, which represents the currently exposed value. Modifying it will notify the listeners:Provider<int>((ref) { ref.listen(onIncrementProvider, (_) { ref.state++; }); return 0; });
-
StateProvider
'sref
now has acontroller
property, which allows the provider to access theStateController
exposed.
-
-
Breaking:
ProviderReference.mounted
is removed. You can implement something similar usingonDispose
:Provider<T>((ref) { var mounted = true; ref.onDispose(() => mounted = false); });
All providers can now be scoped. #
-
Breaking:
ScopedProvider
is removed.
To migrate, changeScopedProvider
s toProvider
s. -
All providers now come with an extra named parameter called
dependencies
. This parameter optionally allows defining the list of providers/families that this new provider depends on:final a = Provider(...); final b = Provider((ref) => ref.watch(a), dependencies: [a]);
By doing so, this will tell Riverpod to automatically override
b
ifa
gets overridden.
Updated AsyncValue
: #
-
Breaking
AsyncValue.copyWith
is removed -
Breaking
AsyncValue.error(..., stacktrace)
is now a named parameter instead of postional parameter. -
Deprecated
AsyncValue.data
in favor ofAsyncValue.value
-
Allowed
AsyncData
,AsyncError
andAsyncLoading
to be extended -
Added
AsyncValue.whenOrNull
, similar towhenOrElse
but instead of an "orElse" parameter, returnsnull
. -
Added
AsyncValue.value
, which allows reading the value without handling loading/error states. -
AsyncError
can now be instantiated withconst
. -
Added
StateController.update
, to simplify updating the state from the previous state:final provider = StateController((ref) => 0); ... ref.read(provider).update((state) => state + 1);
-
It is no longer allowed to use
ref.watch
orref.read
inside a selector:provider.select((value) => ref.watch(something)); // KO, cannot use ref.watch inside selectors
-
FutureProvider now creates a
FutureOr<T>
instead of aFuture<T>
.
That allows bypassing the loading state in the event where a value was synchronously available.
Bug fixes #
- Fixed a bug where widgets were not rebuilding in release mode under certain conditions
- FIX: StreamProvider.last no longer throws a StateError when no value were emitted (#296).
- fixed an issue where when chaining providers, widgets may re-render a frame late, potentially causing a flicker. (see #648)
1.0.0-dev.10 #
Fixed a bug where reading a provider within a consumer could throw (#796)
1.0.0-dev.9 #
Fix an issue where *Provider.autoDispose
were not able to specify the
dependencies
parameter.
1.0.0-dev.8 #
Future/StreamProvider #
-
FutureProvider now creates a
FutureOr<T>
instead of aFuture<T>
That allows bypassing the loading state in the event where a value was synchronously available. -
During loading and error states,
FutureProvider
andStreamProvider
now expose the latest value throughAsyncValue
.
That allows UI to show the previous data while some new data is loading, inatead of showing a spinner:final provider = FutureProvider<User>((ref) async { ref.watch(anotherProvider); // may cause `provider` to rebuild return fetchSomething(); }) ... Widget build(context, ref) { return ref.watch(provider).when( error: (err, stack, _) => Text('error'), data: (user) => Text('Hello ${user.name}'), loading: (previous) { if (previous is AsyncData<User>) { return Text('loading ... (previous: ${previous.value.name})'}); } return CircularProgressIndicator(); } ); }
AsyncValue #
- Breaking
AsyncValue.copyWith
is removed - Breaking
AsyncValue.error(..., stacktrace)
is now a named parameter instead of postional parameter. - Breaking
AsyncValue.when(loading: )
and ``AsyncValue.when(error: )(and
when` variants) now receive an extra "previous" parameter. - Deprecated
AsyncValue.data
in favor ofAsyncValue.value
- Allowed
AsyncData
,AsyncError
andAsyncLoading
to be extended - Added
AsyncValue.whenOrNull
, similar towhenOrElse
but instead of an "orElse" parameter, returnsnull
. - Added
AsyncValue.value
, which allows reading the value without handling loading/error states. AsyncError
can now be instantiated withconst
.AsyncLoading
andAsyncError
now optionally includes the previous state.
General #
-
Breaking All
overrideWithProvider
methods are removed.
To migrate, instead useoverrideWithValue
. -
All providers now come with an extra named parameter called
dependencies
. This parameter optionally allows defining the list of providers/families that this new provider depends on:final a = Provider(...); final b = Provider((ref) => ref.watch(a), dependencies: [a]);
By doing so, this will tell Riverpod to automatically override
b
ifa
gets overridden. -

inside a selector:provider.select((value) => ref.watch(something)); // KO, cannot user ref.watch inside selectors
Bug-fixes #
- fixed a bug where providers were rebuilding even when not being listened to
- fixed
ref.listen
now working when downcasting the value of a provider. - fixed a bug where disposing a scoped

could cause otherProviderContainer
s to stop working. - fixed an issue where conditionally depending on an "autoDispose" provider may not properly dispose of it (see #712)
- fixed an issue where when chaining providers, widgets may re-render a frame late, potentially causing a flicker. (see #648)

0.14.0+3 #
Removed an assert that could cause issues when an application is partially migrated to null safety.
0.14.0+1 #
- Re-added
StateProvider.overrideWithValue
/StateProvider.overrideWithProvider
that were unvoluntarily removed.
0.14.0 #
-
BREAKING CHANGE The
Listener
/LocatorMixin
typedefs are removed as the former could cause a name conflict with the widget namedListener
and the latter is not supported when using Riverpod. -
BREAKING CHANGE The syntax for using
StateNotifierProvider
was updated. Before:class MyStateNotifier extends StateNotifier<MyModel> {...} final provider = StateNotifierProvider<MyStateNotifier>((ref) => MyStateNotifier()); ... Widget build(context, watch) { MyStateNotifier notifier = watch(provider); MyModel model = watch(provider.state); }
After:

See also https://github.com/rrousselGit/river_pod/issues/341 for more information.
-
BREAKING CHANGE It is no longer possible to override
StreamProvider.stream/last
andFutureProvider.future
. -
feat: Calling
ProviderContainer.dispose
multiple time no longer throws. This simplifies the tear-off logic of tests. -
feat: Added
ChangeNotifierProvider.notifier
andStateProvider.notifier
They allow obtaining the notifier associated with the provider, without causing widgets/providers to rebuild when the state updates. -
fix: overriding a
StateNotifierProvider
/ChangeNotifierProvider
withoverrideWithValue
now correctly listens to the notifier.
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

0.13.0-nullsafety.0 #
Migrated to null-safety
0.12.2 #
- Exported
AutoDisposeProviderRefBase
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 exportsStateNotifier
- 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 support0.12.0
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>((ProviderRefBase 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
toProviderContainer.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 acceptsnull
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 multipleProviderScope
.
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
andProvider
. 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
(nowProvider
) 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
toProviderContainer
-
Renamed
ProviderStateOwnerObserver
toProviderObserver
-
It is no longer possible to override a provider anywhere in the widget tree. Providers can only be overridden in the top-most
ProviderContainer
. -
Providers can now read values which may change over time using
ref.read
andref.watch
. When usingref.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-mostProviderContainer
. -
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 aStream<T>
but anAsyncValue<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 aFuture<T>
but anAsyncValue<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 useref.read
/ref.watch
to achieve 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 intoProviderContainer.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 to.
- Added
ScopedProvider
, a new kind of provider that can be overridden anywhere in the widget tree. Normal providers cannot read aScopedProvider
.
0.5.1 #
- Fixed the documentation of
StateNotifierProvider
incorrectly showing the documentation ofStreamProvider
. - Improve the documentation of
StateProvider
.
0.5.0 #
- Changed
ComputedFamily
intoComputed.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 forAsyncValue.when
to handle only thedata
case and do nothing for the error/loading cases. -
Fixed a bug that caused [Computed] to crash if it stopped being listened to then was listened to 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 asref.dependOn
- Deprecated
ref.dependOn(streamProvider).stream
andref.dependOn(futureProvider).future
in favor of a universalref.dependOn(provider).value
. - added
ref.read(provider)
, syntax sugar forref.dependOn(provider).value
.
0.1.0 #
Initial release
