The class you're looking for is Magento\Catalog\Pricing\Price\FinalPrice
The below code will double the final price as an example:
etc/frontend/di.xml
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
<type name="Magento\Catalog\Pricing\Price\FinalPrice">
<plugin name="vendorname_modulename_catalog_pricing_price_finalprice" type="VendorName\ModuleName\Plugin\FinalPrice" />
</type>
</config>
Plugin/FinalPrice.php
<?php
namespace VendorName\ModuleName\Plugin;
class FinalPrice
{
/**
* @param \Magento\Catalog\Pricing\Price\FinalPrice $subject
* @param float $result
* @return float
*/
public function afterGetValue(\Magento\Catalog\Pricing\Price\FinalPrice $subject, $result)
{
return $result * 2;
}
}
If you want to use event observer for the price change on the product page. You may use following event
catalog_controller_product_view
and in the observer you may use following code.
public function execute(Observer $observer)
{
$customPrice = 4;
$product = $observer->getEvent()->getProduct();
$product->setFinalPrice($customPrice);
}
