operator []= method
Associates the key
with the given value
.
If the key was already in the map, its associated value is changed. Otherwise the key/value pair is added to the map.
Implementation
@override
operator []=(K key, V value) {
bool isSet = _inner.containsKey(key);
_inner[key] = value;
_changes
.add(MapChange(MapEntry(key, value), isSet ? MapOp.set : MapOp.add));
}
