# last property

E get last
override

The last element.

Throws a StateError if `this` is empty. Otherwise may iterate through the elements and returns the last one seen. Some iterables may have more efficient ways to find the last element (for example a list can directly access the last element, without iterating through the previous ones).

## Implementation

    E get last {
      final root = _root;
      if (root == null) throw IterableElementError.noElement();
      return (_root = _splayMax(root)).key;
    }
