# MapEntry<K, V> class final

A key/value pair representing an entry in a Map.

The Map interface contains various methods that can inspect or modify the map based on entry objects.

    final map = {'1': 'A', '2': 'B'};
    map.addEntries([
     MapEntry('3', 'C'),
     MapEntry('4', 'D'),
    ]);
    print(map); // {1: A, 2: B, 3: C, 4: D}

Do not extend or implement the `MapEntry` class. If the Dart language introduces value types, the `MapEntry` class will be changed to such a type, and will likely no longer be able to be implemented or extended by classes.
