String getText([
  1. int? from,
  2. int? to
])

Implementation

String getText([int? from, int? to]) {
  if (from == null || from < 0) {
    from = 0;
  }

  if (to == null || to > _length) {
    to = _length;
  }

  final builder = StringBuffer();
  for (var i = from; i < to; i++) {
    final codePoint = getCodePoint(i);
    final width = getWidth(i);
    if (codePoint != 0 && i + width <= to) {
      builder.writeCharCode(codePoint);
    }
  }

  return builder.toString();
}
