Map<K, V>.fromIterables constructor
Creates a map associating the given keys
to the given values
.
The map construction iterates over keys
and values
simultaneously, and adds an entry to the map for each pair of key and value.
List<String> letters = ['b', 'c']; List<String> words = ['bad', 'cat']; var map = Map.fromIterables(letters, words); // map is {"b": "bad", "c": "cat"}
If keys
contains the same object multiple times, the value of the last occurrence overwrites any previous value.
The two Iterables must have the same length.
The created map is a LinkedHashMap. A LinkedHashMap
requires the keys to implement compatible operator==
and hashCode
. It iterates in key insertion order.
Implementation
factory Map.fromIterables(Iterable<K> keys, Iterable<V> values) = LinkedHashMap<K, V>.fromIterables;
