An object that stores the state of the providers and allows overriding the behavior of a specific provider.

If you are using Flutter, you do not need to care about this object (outside of testing), as it is implicitly created for you by ProviderScope.

debugCanModifyProviders ↔ (void Function?()?): A debug utility used by flutter_riverpod/hooks_riverpod to check if it is safe to modify a provider.

debugChildren → List<ProviderContainer>: All the containers that have this container as parent.
read-only
debugId → String: A unique ID for this object, used by the devtool to differentiate two ProviderContainer.
@visibleForTesting, read-only
depth → int: How deep this ProviderContainer is in the graph of containers.
final
hashCode → int: The hash code for this object.
read-only, inherited
runtimeType → Type: A representation of the runtime type of the object.

vsync → void Function(void task()): A function that controls the refresh rate of providers.
read-only
vsyncOverride ↔ (void Function?(void task())?): A way to override vsync, used by Flutter to synchronize a container with the widget tree.
read / write

dispose() → void: Release all the resources associated with this ProviderContainer.
getAllProviderElements() → Iterable<ProviderElementBase>: Traverse the ProviderElementBases associated with this ProviderContainer.
getAllProviderElementsInOrder() → Iterable<ProviderElementBase>: Visit all nodes of the graph at most once, from roots to leaves.
listen<State>(ProviderListenable<State> provider, void listener(State? previous, State next), {bool fireImmediately = false, void onError(Object error, StackTrace stackTrace)?}) → ProviderSubscription<State>: Subscribe to this provider.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.
inherited
pump() → Future<void>: Awaits for providers to rebuild/be disposed and for listeners to be notified.
read<Result>(ProviderBase<Result> provider) → Result: Reads a provider without listening to it and returns the currently exposed value.
readProviderElement<State>(ProviderBase<State> provider) → ProviderElementBase<State>: Reads the state of a provider, potentially creating it in the process.
refresh<Created>(ProviderBase<Created> provider) → Created: Forces a provider to re-evaluate its state immediately, and return the created value.
toString() → String: A string representation of this object.
