operator [] method

  1. @override
V operator [](
  1. Object key

The value for the given key, or null if key is not in the map.

Some maps allow null as a value. For those maps, a lookup using this operator cannot distinguish between a key not being in the map, and the key being there with a null value. Methods like containsKey or putIfAbsent can be used if the distinction is important.


V operator [](Object key) => _wrappedMap[key];
