Flutter ListViewBuilder Listile Header Text

I have a set of tabs, within one of the tabs i have a futurebuilder that has a listviewBuilder and ListTile. How do I add a header container/Sizedbox above the listtiles.
I have tried adding columns, SingleChildScrollView, CustomScrollView with slivers but keeps getting errors

Widget localAttractionsTab() {
    return FutureBuilder(
        future: localAttractions(widget.locationId),
        builder: (BuildContext context, AsyncSnapshot<Amenities> snapshot) {
          if (snapshot.connectionState == ConnectionState.waiting) {
            return const Center(child: CircularProgressIndicator());
          } else if (snapshot.error != null) {
            return const Center(child: Text('an error occured!'));
          } else {
            return
             ListView.builder(
                itemCount: snapshot.data!.attraction.length,
                itemBuilder: (context, index) {
                  return ListTile(
                    title: Text(snapshot.data!.attraction[index].attractionname),
                    //subtitle: Text(el.),
                    onTap: () {
                      //Got To Amenity Details Page
                      Navigator.of(context).push(
                        MaterialPageRoute(
                          builder: (context) => AttractionDetailsScreen(
                              attractionID: snapshot.data!.attraction[index].id
                             ),
                        ),
                      );
                    },
                  );
                }
            );
          }
        });
  }

>Solution :

Widget localAttractionsTab() {
    return FutureBuilder(
        future: localAttractions(widget.locationId),
        builder: (BuildContext context, AsyncSnapshot<Amenities> snapshot) {
          if (snapshot.connectionState == ConnectionState.waiting) {
            return const Center(child: CircularProgressIndicator());
          } else if (snapshot.error != null) {
            return const Center(child: Text('an error occured!'));
          } else {
            return
             ListView.builder(
                itemCount: snapshot.data!.attraction.length + 1,
                itemBuilder: (context, index) {
                  if(index == 0){
                    return Container(); // add whatever you want here
                  }
                  else{
                    return ListTile(
                    title: Text(snapshot.data!.attraction[index].attractionname),
                    //subtitle: Text(el.),
                    onTap: () {
                      //Got To Amenity Details Page
                      Navigator.of(context).push(
                        MaterialPageRoute(
                          builder: (context) => AttractionDetailsScreen(
                              attractionID: snapshot.data!.attraction[index].id
                             ),
                        ),
                      );
                    },
                  );
                  }
                  
                }
            );
          }
        });
  }
