LinkedHashMap<K, V>.fromIterable constructor

LinkedHashMap<K, V>.fromIterable(

1. Iterable iterable,
2. {K key(
   1. dynamic element
   ),
3. V value(
   1. dynamic element
   )}

)

Creates a LinkedHashMap where the keys and values are computed from the iterable.

For each element of the iterable this constructor computes a key/value pair, by applying key and value respectively.

The keys of the key/value pairs do not need to be unique. The last occurrence of a key will simply overwrite any previous value.

If no values are specified for key and value the default is the identity function.

Implementation

factory LinkedHashMap.fromIterable(Iterable iterable,
    {K Function(dynamic element)? key, V Function(dynamic element)? value}) {
  LinkedHashMap<K, V> map = LinkedHashMap<K, V>();
  MapBase._fillMapWithMappedIterable(map, iterable, key, value);
  return map;
}
