# addAll method

void addAll(

1. Iterable<E> iterable

)
override

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> iterable) {
      int i = this.length;
      for (E element in iterable) {
        assert(this.length == i || (throw ConcurrentModificationError(this)));
        add(element);
        i++;
      }
    }
