operator [] method

Map operator [] (dynamic key)

override

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

Some maps allow keys to have 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 having a null value. Methods like containsKey or putIfAbsent can be used if the distinction is important.

Implementation

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