• Iterable<Map<K, V>>

Methods

filterKey(K key, V filter(V val)) → void

Filter key for each element (a Map), using filter.

groupBy<G>(G groupMapper(Map<K, V> e)) → Map<G, List<Map<K, V>>>

Groups elements by groupMapper.

groupByKey<G>(K key, {V? defaultKeyValue}) → Map<V, List<Map<K, V>>>

Groups by key of each element (a Map).

keepKeys(Iterable<K> keys) → void

Calls keepKeys for each element (A Map).

mergeKeysValues<M>(Iterable<Map<K, V>> other, M merger(K key, V val1, V val2), {V onAbsentKey(K key, bool other)?}) → List<Map<K, M>>

mergeKeysValuesToList(Iterable<Map<K, V>> other, {V onAbsentKey(K key, bool other)?}) → List<Map<K, List<V>>>

removeKeys(Iterable<K> keys) → void

Removes keys for each element (a Map).

renameKeys(Map<K, K> rename) → void

Removes keys for each element (a Map) using rename mapper.

sortedByKey(K key, {Comparator<V>? compare}) → List<Map<K, V>>

Returns a sorted List of this Iterable<Map>, sorting by key.

toKeyValues(K key, {V? defaultKeyValue}) → List<V>

Returns the key value of each element (a Map).

toKeyValuesNullable(K key) → List<V?>

Same as toKeyValues, but accepts null values.
