# last property Null safety

E last
override

Returns 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 {
      if (_count == 0) throw IterableElementError.noElement();
      return _last!.key;
    }
