Map<K, V2> mapValues<V2>(
  1. V2 mapper(
    1. V
    )
)

Returns a new map with values transformed by the mapper function.

Example:

{'a': 1, 'b': 2}.mapValues((v) => v * 2);
// {'a': 2, 'b': 4}

Map<K, V2> mapValues<V2>(V2 Function(V) mapper) =>
    map((K key, V value) => MapEntry<K, V2>(key, mapper(value)));
