addAll method

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

void addAll(Iterable<E> elements) {
  int oldLength = length;
  _inner.addAll(elements);
  for (int i = 0; i < elements.length; i++) {
    _changes.add(ListChange<E>.insert(elements.elementAt(i), oldLength + i));
  }
}
