Flutter List View Builder Item Count Datatable with MySql Database

I am trying to achieve on making a Datatable in flutter with the use of Mysql as my database, it is functioning properly but it also loops the datatable with the item count, for example this image down below. I've been trying using map all the data are there inside the datatable but it loops the same data.

My Code:

 FutureBuilder(
                    future: fetchClients(),
                    builder: (context, snapshot) {
                      if (snapshot.hasData) {
                        return Container(
                          child: ListView.builder(
                            physics: NeverScrollableScrollPhysics(),
                            itemCount: 3,
                            shrinkWrap: true,
                            itemBuilder: (BuildContext context, index) {
                              Contacts contacts = snapshot.data[index];
                              return Card(
                                child: Column(
                                  children: [
                                    Container(

                                            topLeft: Radius.circular(5.0),
                                            topRight: Radius.circular(5.0),
