associate<K, V> method

Map<K, V> associate<K, V>(
  1. MapEntry<K, V> transform(
    1. E element
    )
)

Returns a Map containing key-value pairs provided by transform function applied to elements of this collection.

If any of two pairs would have the same key the last one gets added to the map.

Implementation

Map<K, V> associate<K, V>(MapEntry<K, V> Function(E element) transform) {
  final map = <K, V>{};
  for (final element in this) {
    final entry = transform(element);
    map[entry.key] = entry.value;
  }
  return map;
}
