operator [] method

Map? operator [](
  1. dynamic key
)
override

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.

Implementation

Map? operator [](dynamic key) => _getItem(key);
