operator [] method

  1. @override
dynamic operator [] (
  1. Object 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

@override
dynamic operator [](Object key) {
  return _data[key];
}
