@override
String tabSemanticsLabel({ required int tabIndex, required int tabCount }) {
  assert(tabIndex >= 1);
  assert(tabCount >= 1);
  final String template = tabSemanticsLabelRaw;
  return template
    .replaceFirst(r'$tabIndex', _decimalFormat.format(tabIndex))
    .replaceFirst(r'$tabCount', _decimalFormat.format(tabCount));
}
