How to override template using helper function in Magento2

In this guide, we will learn how can we call our custom template file in layout referenceBlock from a helper function.

1. Add the below code in your layout file:

<referenceBlock name="test_block">
            <action method="setTemplate">
                <argument name="template" xsi:type="helper" helper="Webkul\Test\Helper\Data::getTemplate"></argument>

            </action>
          
 </referenceBlock>

2. Create getTemplate function in your helper function.

public function getTemplate()
{
        
     $template =  'Webkul_Test::test.phtml';
        
     return $template;
}
