operator []= method

@override void operator []=(K key, V value)

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
void operator []=(K key, V value) {
  bool containsKey = _map.containsKey(key);
  V? removed = containsKey ? _map[key] : null;
  _map[key] = value;
  notifyListeners(MapChangeDetails<K, V>([MapEntry(key, value)],
      [if (containsKey) MapEntry(key, removed as V)]));
}
