dart中是否有类似c++的迭代器

class MyIterable implements Iterable<int> {
  final int _start;
  final int _end;

  MyIterable(this._start, this._end);

  Iterator<int> iterator() {
    return MyIterator(_start, _end);
  }
}

class MyIterator implements Iterator<int> {
  int _current;
  final int _end;

  MyIterator(this._current, this._end);

  bool moveNext() {
    if (_current < _end) {
      _current++;
      return true;
    } else {
      return false;
    }
  }

  int get current => _current;
}

void main() {
  var iterable = MyIterable(1, 5);
  var iterator = iterable.iterator();

  while (iterator.moveNext()) {
    print(iterator.current);
  }
}
