Text style not getting set on search item

[WasimMemon]

How to change text style of popup items. I have tried to set font size small in all possible place, but it is not working. Still, it displays in big size. Check below screenshots.

And hint also not getting displayed in search box.

FormBuilderSearchableDropdown<AddressState>(
      popupProps: PopupProps.menu(showSearchBox: true, searchFieldProps: TextFieldProps(style: TextStyle(fontSize: 12),
              )),
      items: stateList,
      itemAsString: (model) => model.name ?? "",
      name: "addressState",
      initialValue: _businessState,
      compareFn: (item1, item2) => item1.isSelected != item2.isSelected,
      //isExpanded: true,
      dropdownSearchTextStyle: TextStyle(fontSize: 12),
     dropdownSearchDecoration: InputDecoration(
        hintText: 'Search',
          labelStyle: TextStyle(fontSize: 12),
      ),
      onChanged: (newValue) {
        if (!_businessState.isEqual(newValue!)) {
        }
      },
      decoration: InputDecoration(
        labelStyle: Theme.of(context).textTheme.bodySmall,
        hintText: S.current.labelState,
        contentPadding: EdgeInsets.only(left: 10, right: 12),
        border: Theme.of(context).inputDecorationTheme.border,
        focusedBorder: Theme.of(context).inputDecorationTheme.focusedBorder,
        errorBorder: Theme.of(context).inputDecorationTheme.errorBorder,
      ),
      filterFn: (item, filter) => item.name!.toLowerCase().contains(filter.toLowerCase()),
    );
