</config>

The step2 to overriding or rewriting Magento 2 block is to create a ListProduct.php block file in the following directory QaisarSatti/HelloWorld/Block/Rewrite/Product

<?php
/**
* Catalog Product Rewrite Block
*
* @category QaisarSatti

*/

namespace QaisarSatti\HelloWorld\Block\Rewrite\Product;
