# current property Null safety

T current
override

Returns the current element.

If the iterator has not yet been moved to the first element (moveNext has not been called yet), or if the iterator has been moved past the last element of the Iterable (moveNext has returned false), then current is unspecified. An Iterator may either throw or return an iterator specific default value in that case.

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 as T;
