A string containing the current rune.
For runes outside the basic multilingual plane, this will be a String of length 2, containing two code units.
Returns null if current is null.
String get currentAsString { if (_position == _nextPosition) return null; if (_position + 1 == _nextPosition) return string[_position]; return string.substring(_position, _nextPosition); }
