# HashMap<K, V>.fromEntries constructor

HashMap<K, V>.fromEntries(

1. Iterable<MapEntry<K, V>> entries

)

Creates a HashMap containing the entries of `entries`.

Returns a new `HashMap<K, V>` where all entries of `entries` have been added in iteration order.

If multiple `entries` have the same key, later occurrences overwrite the earlier ones.

Example:

    final numbers = [11, 12, 13, 14];
    final map = HashMap.fromEntries(numbers.map((i) => MapEntry(i, i * i)));
    print(map); // {11: 121, 12: 144, 13: 169, 14: 196}

## Implementation

    factory HashMap.fromEntries(Iterable<MapEntry<K, V>> entries) =>
        HashMap<K, V>()..addEntries(entries);
