  if (picker!.onBuilderItem != null) {
    final v = picker!.onBuilderItem!(
        context, item.value.toString(), item.text, isSel, _col, index);
    if (v != null) return makeText(v, null, isSel);
  }
  if (item.text != null) {
    return isSel && picker!.selectedTextStyle != null
        ? Center(
