flutter fetch data textformfield

Question

This is my search code when i search and show listview how can i want the textformfield outside listview to fetch after complete search?

I typed some text into the search box and the data was fetched successfully. But I want the textfield outside the listview to have text after search, what should I do? i am practicing

onSearch(String text) async {
if (text.isNotEmpty) {
  List<Item> itemList = [];
  for (var item in items) {
    if (item.custnum == text.toString().toLowerCase().toUpperCase()) {
      itemList.add(item);
      setState(() {
        searchitems.clear();
        searchitems.addAll(itemList);
        print('name : ${searchitems[0].name}');
        if (searchitems.isEmpty) {
          searchitems = [];
          // print('searchitems : ${searchitems[0].address!.length}');
          // print('searchitems : ${searchitems[0].address!}');
        }
      });
    }
  }
} else {
  setState(() {
    searchitems.clear();
    // searchitems.addAll(items);
    print('searchitems : $searchitems');
  });
}

This is TextFormField

                TextFormField(
                          decoration: InputDecoration(
                            labelText: 'name',
                            labelStyle: TextStyle(
                                fontFamily: 'supermarket', fontSize: 14),
                            isDense: true,
                          ),
                        ),

This is listview

child: searchitems.isNotEmpty
                  ? ListView.builder(
                      controller: controllerlistview,
                      itemCount: searchitems[0].address!.length,
                      itemBuilder: (context, index) {
                        return InkWell(
                          onTap: () {
                            Navigator.push(
                                context,
                                MaterialPageRoute(
                                    builder: ((context) => EditAddressPage(
                                        custaddr:
                                            searchitems[0].address![0]))));
                          },

Just assign this to your TextFormField and you can get the search box value from it.

        final textController=TextEditingController();

         TextFormField(
        decoration: InputDecoration(
          labelText: 'name',
          labelStyle: TextStyle(
              fontFamily: 'supermarket', fontSize: 14),
          isDense: true,
        ),
        controller: textController,
      ),
