add method

@override void add(E element)

Adds value to the end of this list, extending the length by one.

The list must be growable.

final numbers = <int>[1, 2, 3];
numbers.add(4);
print(numbers); // [1, 2, 3, 4]

Implementation

@override
void add(E element) {
  // Listen to the element if asked to and if it is possible
  if (_propagateNotification &&
      element != null &&
      element is ChangeNotifier) {
    element.addListener(_propagate);
  }

  _values.add(element);
  notifyListeners();
}
