Extension that ads cached methods to a Map.

• Map<K, V>

Methods

checkCachedEntry(K key) → void

checkCacheLimit(int? cacheLimit) → int

Checks if this Map.length is bigger than cacheLimit and removes elements to not exceed the cacheLimit.

getCached(K key, V computer(), {int? cacheLimit}) → V

Returns key value or computes it and caches it. See checkCachedEntry, checkCacheLimit and getCachedAsync.

getCachedAsync(K key, FutureOr<V> computer(), {int? cacheLimit}) → FutureOr<V>

Same as getCached but accepts a computer that returns a Future. See checkCachedEntry, checkCacheLimit and getCachedAsync.

getCachedAsyncNullable(K key, FutureOr<V?> computer(), {int? cacheLimit}) → FutureOr<V?>

getCachedNullable(K key, V? computer(), {int? cacheLimit}) → V?

getIfCached(K key, {int? cacheLimit}) → V?

Returns key value, checking if it's still valid. See checkCachedEntry and checkCacheLimit.
