Remove container from ListView Builder when clicked to remove - flutter

Question

The ListView Builder generates containers. Inside the container, it has another container to remove the first one container.
I already tried with Dismissible, but it didn't work... this question is quite similar, but I couldn't applly for my code:
removing item from ListView.builder Flutter
Hope someone can help :)))
Here is the code:
ListView.builder(
scrollDirection: Axis.horizontal,
shrinkWrap: true,
padding: EdgeInsets.only(bottom: 10),
itemCount:
snapshot.data != null ? snapshot.data.length : 0,
itemBuilder: (BuildContext context, int index) {
OrdersModel orderItem = snapshot.data[index];
return InkWell(
//onTap
child: Container(
padding: EdgeInsets.only(
bottom: 10, top: 10, left: 5, right: 5),
margin: EdgeInsets.only(left: 5, right: 15),
width: 187,
decoration: BoxDecoration(
borderRadius: BorderRadius.all(
Radius.circular(20),

BoxShadow(

mainAxisAlignment:
MainAxisAlignment.center,
children: [
Text(
"REMOVE ${orderItem.number}",
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.white,
),
),
],
),
),
onLongPress: () async {
Navigator.push(
context,
MaterialPageRoute(
builder: (context) =>
OrderDetailsPage(),
),
);
},
),
),
),
],
),
),
onTap: () {},
);
},
);

Answer 1

U probably can just call a snapshot.data.removeAt(index) inside your list item, like that:
ListView.builder(
itemCount: items.length,
itemBuilder: (context, index) {
final item = items[index];
return ListTile(title: Text('$item --- Click to remove me'),onTap:(){
setState(() {
items.removeAt(index);
});
});
},
),

You ca use Dismissible https://flutter.dev/docs/cookbook/gestures/dismissible for your solution
