addAll method

@override void addAll(Iterable<E> elements)

Appends all objects of iterable to the end of this list.

Extends the length of the list by the number of objects in iterable. The list must be growable.

final numbers = <int>[1, 2, 3];
numbers.addAll([4, 5, 6]);
print(numbers); // [1, 2, 3, 4, 5, 6]

Implementation

@override
void addAll(Iterable<E> elements) {
  for (E element in elements) {
    // Listen to the element if asked to and if it is possible
    if (_propagateNotification &&
        element != null &&
        element is ChangeNotifier) {
      element.addListener(_propagate);
    }

    // Add the element to the list
    _values.add(element);
  }

  // Notify only once
  notifyListeners();
}
