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();
}
