# asMap method

Map<int, E> asMap ()

Returns an unmodifiable Map view of `this`.

The map uses the indices of this list as keys and the corresponding objects as values. The `Map.keys` Iterable iterates the indices of this list in numerical order.

    List<String> words = ['fee', 'fi', 'fo', 'fum'];
    Map<int, String> map = words.asMap();
    map[0] + map[1];   // 'feefi';
    map.keys.toList(); // [0, 1, 2, 3]

## Implementation

    Map<int, E> asMap();
