StreamResource<K, V> class

Resource used for managing the data. Allows load, invalidate, clear local data or use with delegated _fetch callback.

Constructors

StreamResource(Future<V> _fetch(K key, ResourceFetchArguments? arguments)?, K _resourceKey, CacheDurationResolver<K, V> _cacheDurationResolver, CacheStorage<K, V> _storage)

Creates an instance. Usually you don't need to create directly. It is used inside the repositories.

Methods

close() → Future<void>

Deletes the cached value and closes the resource. After that, it cannot be used.

invalidate() → Future<void>

Invalidates the cached value and force a resource reload.

load({bool forceReload = false, void doOnStore(V)?, bool allowEmptyLoading = false, ResourceFetchArguments? fetchArguments}) → Stream<Resource<V>>

Trigger resource loading from cache or with _fetch. forceReload reload even if cache is valid. allowEmptyLoading put empty loading to prevent previous SUCCESS to return. doOnStore callback to modify data before putting it in the storage. fetchArguments additional arguments passed to _fetch if provided.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

putValue(V value) → Future<void>

Put or replace value by _resourceKey in the storage.

toString() → String

A string representation of this object.

inherited

updateValue(V? changeValue(V? value), {bool notifyOnNull = false}) → Future<void>

Update value directly in storage.

Operators

operator ==(Object other) → bool

The equality operator.
