This is the code that I wrote. I am trying the make the listview start right below the text widgets and end right before the pay button.The Listview should disappear just below the Text widgets when scrolling up and right above the pay button when scrolling down . Any help is appreciated.

 import 'package:ecommerce/Models/shop_functions.dart';
 import 'package:flutter/material.dart';
 import 'package:provider/provider.dart';
 import 'package:ecommerce/Models/shop_functions.dart';

 class Cart extends StatefulWidget {   
 const Cart({super.key});

 @override
 State<Cart> createState() => _CartState();
  }

  class _CartState extends State<Cart> {
  @override
  Widget build(BuildContext context) {
  final palette =Theme.of(context).colorScheme;


 return Consumer<ShopFunctions>(
  builder: (context, value , child) {

    double priceTotal = 0 ;

    for(var val in value.cart)
      {
        priceTotal += val.price;
      }

    return Scaffold(
      floatingActionButton: Container(
        width: 200,
        child: FloatingActionButton(
          shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(8)),
          backgroundColor: Colors.blue,
          onPressed: () {  },
          child: Text('Pay Rs ${priceTotal}' ,
          style: TextStyle(
            color: Colors.white
          ),
          ),

        ),
      ),
      floatingActionButtonLocation: FloatingActionButtonLocation.centerFloat,
