Let’s Start Out With Coding

Step 1: First, we need to create a “Registration.php” file inside our extension at the following path,

app\code\Vendor\Extension

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Vendor_Extension',
    __DIR__
);

Step 2: After that, we need to create a “module.xml” file inside the extension etc folder.

app\code\Vendor\Extension\etc

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Vendor_Extension" setup_version="1.0.0" schema_version="1.0.0"/>
</config>

Step 3: After that, we need to create a “checkout_cart_index.xml” file inside the path folder to add the file in the module.

app\code\Vendor\Extension\view\frontend\layout

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceContainer name="checkout.cart.totals.container">
            <block class="Magento\Framework\View\Element\Template" name="checkout.cart.custom.block" before="checkout.cart.totals" template="Vendor_Extension::custom-block.phtml" />
        </referenceContainer>
    </body>
</page>

Step 4: Lastly, Create the “custom-block.phtml” file inside the below path folder in the module.

app\code\Vendor\Extension\view\frontend\templates

<?php echo "Custom Block"; ?>
