# map<K2, V2> method Null safety

Map<K2, V2> map <K2, V2>(

1. MapEntry<K2, V2> transform(
   1. K key,
   2. 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] as V);
        result[entry.key] = entry.value;
      }
      return result;
    }
