first property

E first
override

Returns the first element.

Throws a StateError if this is empty. Otherwise returns the first element in the iteration order, equivalent to this.elementAt(0).

Implementation

E get first {
  _DoubleLinkedQueueEntry<E> firstEntry = _sentinel._nextLink;
  return firstEntry._element;
}
