# Map<K, V>.fromEntries constructor

Map<K, V>.fromEntries(

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

)

Creates a new map and adds all entries.

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

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

Equivalent to the map literal:

    <K, V>{for (var e in entries) e.key: e.value}

Example:

    final moonCount = <String, int>{'Mercury': 0, 'Venus': 0, 'Earth': 1,
      'Mars': 2, 'Jupiter': 79, 'Saturn': 82, 'Uranus': 27, 'Neptune': 14};
    final map = Map.fromEntries(moonCount.entries);

## Implementation

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