# addAll method

void addAll (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`. Throws an UnsupportedError if this list is fixed-length.

## Implementation

    void addAll(Iterable<E> iterable) {
      var list = (JS('bool', '# instanceof Array', iterable))
          ? iterable
          : new List.from(iterable);
      callMethod('push', list);
    }
