rawIndex property
Returns 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;
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 then string will set current to null.
Implementation
void set rawIndex(int rawIndex) {
RangeError.checkValidIndex(rawIndex, string, "rawIndex");
reset(rawIndex);
moveNext();
}
