magento2.4 – Show product attribute on product page magento 2.4

i need to show an attribute to product page under the name of the product. The attribute is text and the code is plustile

I try to load it to a shopbybrand extension that has a block in the wanted area with the code

<?php
// check attribute exists (Where 'dimension' is the attribute code for your attribute)
if ($attribute = $this->getProduct()->getResource()->getAttribute('flooring_width')): ?>
    <?php
    // get label for the current store (in case you have multiple stores and languages)
    $_attribute_label = $attribute->getStoreLabel(Mage::app()->getStore()->getName());
    // get the attribute value (for other attributes change getDimension to getName where name is the name of your attribute );
    $_attribute_value = $this->getProduct()->getFlooringWidth();
    ?>
    <?php
    // check there is a value for the attribute
    if (isset($_attribute_value)): ?>
        <p>
            <?php echo $_attribute_label . ': ' . $_attribute_value; ?>
        </p>
    <?php endif; ?>
<?php endif; ?>

or something else like that i get
Error: Call to a member function getResource() on null in

i try to make an extension like

but with no success

Can you advise for the correct way to do it or
Do you know any extension to do this?
