# rawIndex property

int get rawIndex

The starting position of the current rune in the string.

Returns -1 if there is no current rune (current is -1).

## Implementation

    int get rawIndex => (_position != _nextPosition) ? _position : -1;

set rawIndex (int rawIndex)

Resets the iterator to the rune at the specified index of the string.

Setting a negative `rawIndex`, or one greater than or equal to `string.length`, is an error. So is setting it in the middle of a surrogate pair.

Setting the position to the end of the string means that there is no current rune.

## Implementation

    void set rawIndex(int rawIndex) {
      IndexError.check(
        rawIndex,
        string.length,
        indexable: string,
        name: "rawIndex",
      );
      reset(rawIndex);
      moveNext();
    }
