StreamRepository<K, V> class

Repository for resource management.

Constructors

StreamRepository.local({required CacheStorage<K, V> storage})

Creates repository for use as local data storage. Caches data in the passed CacheStorage.

StreamRepository.remote({required FetchData<K, V> fetch, CacheStorage<K, V>? storage, Duration? cacheDuration, CacheDurationResolver<K, V>? cacheDurationResolver})

Creates repository with providing fetch callback, typically used for REST API call. Caches data in the passed CacheStorage. The default is MemoryCacheStorage.

Methods

clear([K? key]) → Future<void>

Clear, delete and dispose resource by key or all resources if a key not passed.

getAll() → Future<List<V>>

Fetch all data from underlying storage.

invalidate(K key) → Future<void>

Invalidate resource by key and reload.

invalidateAll() → Future<void>

Invalidate all resources and reload.

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

Same as stream, but waiting only for the first completed result.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

putValue(K key, V value) → Future<void>

Put value directly in the storage.

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

Creates a stream by key. It emits the cached data, then the fetch result if provided, and after that any changes to the resource due to reloading or invalidating the resource.

toString() → String

A string representation of this object.

inherited

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

Update or replace value by key directly in the storage.

watch() → Stream<List<V>>

Stream of all stored entries that emits on any change of any resource.

Operators

operator ==(Object other) → bool

The equality operator.
