# LinkedHashMap<K, V>.fromIterable constructor Null safety

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;
    }
