map<K2, V2> method

Map<K2, V2>? map<K2, V2>(
  1. MapEntry<K2, V2> convert(
    1. K key,
    2. V value
    )
)

Returns a new map where all entries of this map are transformed by the given convert function.

Implementation

Map<K2, V2>? map<K2, V2>(MapEntry<K2, V2> Function(K key, V value) convert) =>
    value?.map<K2, V2>(convert);
