updateAll method

@override void updateAll(V update(K key, V value))

Updates all values.

Iterates over all entries in the map and updates them with the result of invoking update.

final terrestrial = <int, String>{1: 'Mercury', 2: 'Venus', 3: 'Earth'};
terrestrial.updateAll((key, value) => value.toUpperCase());
print(terrestrial); // {1: MERCURY, 2: VENUS, 3: EARTH}

Implementation

@override
void updateAll(V Function(K key, V value) update) {
  final List<MapEntry<K, V>> added = [];
  final List<MapEntry<K, V>> removed = [];
  for (final entry in _map.entries) {
    V newValue = update(entry.key, entry.value);
    if (_map.containsKey(entry.key)) {
      removed.add(MapEntry(entry.key, _map[entry.key] as V));
    }
    added.add(MapEntry(entry.key, newValue));
  }
  _map.updateAll(update);
  notifyListeners(MapChangeDetails<K, V>(added, removed));
}
