# current property

T current
override

Returns the current element.

Returns `null` if the iterator has not yet been moved to the first element, or if the iterator has been moved past the last element of the Iterable.

The `current` getter should keep its value until the next call to moveNext, even if an underlying collection changes. After a successful call to `moveNext`, the user doesn't need to cache the current value, but can keep reading it from the iterator.

## Implementation

    T get current => _current;
