map<K2, V2> method

Map<K2, V2> map <K2, V2>(MapEntry<K2, V2> transform(K key, V value))
override

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

Implementation 

Map<K2, V2> map<K2, V2>(MapEntry<K2, V2> transform(K key, V value)) {
  var result = <K2, V2>{};
  for (var key in this.keys) {
    var entry = transform(key, this[key]);
    result[entry.key] = entry.value;
  }
  return result;
}
