 $cart = $this->_getCart();
 /* check if cart is empty */
 if (!$this->_getCart()->getQuote()->getItemsCount()) 

 return;
 


 $buyProductXID = explode (",",Mage::getStoreConfig('buyxgety_section1/general/productx_product_id'));
 $buyProductYID = explode (",",Mage::getStoreConfig('buyxgety_section1/general/producty_product_id'));
 $buyProductXminQty = explode (",",Mage::getStoreConfig('buyxgety_section1/general/productx_required_qty'));
 $buyProductXmaxQty = explode (",",Mage::getStoreConfig('buyxgety_section1/general/productx_limit_qty')); 
 $buyProductYDescription = explode (",",Mage::getStoreConfig('buyxgety_section1/general/producty_description'));

 $error="A BuyXGetY Extension cart error was detected!"; 

 try
 
 for($i = 0; $i < count($buyProductXID); $i++)
 if (empty($buyProductYDescription[$i])) 
 $buyProductYDescription[$i]="free gift";
 
 if (empty($buyProductXID[$i])) 
 $buyProductXID[$i]="0";
 
 if (empty($buyProductYID[$i])) 
 $buyProductYID[$i]="0";
 
 if (empty($buyProductXminQty[$i])) 
 $buyProductXminQty[$i]="999";
 
 if (empty($buyProductXmaxQty[$i])) 
 $buyProductXmaxQty[$i]="0";
 
 if ($buyProductXID[$i] !="0" && $buyProductYID[$i] !="0") 
 if ($this->isProductYUnique()) 
 

 $this->buyXgetYfreeCartUpdate((int)$buyProductXID[$i],(int)$buyProductXminQty[$i],(int)$buyProductYID[$i],$buyProductYDescription[$i],(int)$buyProductXmaxQty[$i]); 
 else 
 $error = "Error in Buy X configuration - Product Y is not unique across all extension settings.";

code StwBuyXGetY BuyXGetY ControllerCheckoutCartAdd.php

 namespace StwBuyXGetYBuyXGetYPluginControllerCheckoutCart;
 class Add
 
 public function aroundExecute(MagentoCheckoutControllerCartAdd $add, callable $proceed, OutputInterface $output)
 
 $this->buyXgetYfree();
 $returnValue = $proceed();
 return $returnValue;
 
 public function buyXgetYfree()
 
 echo "buyXgetYfree"; // this is dummy content
 
 

Change your plugin controller to following

class Add

 public function aroundExecute(
 MagentoCheckoutControllerCartAdd $subject,
 Closure $proceed
 ) 
 $this->buyXgetYfree();
 return $proceed();
 

 public function buyXgetYfree()
 
 error_log('buyXgetYfree');
 

When you press addtocart button, basically it's not return any 'echo' content. So you can use error_log or magento 2 log system for checking.

$writer = new ZendLogWriterStream(BP . '/var/log/addToCart.log');
 $logger = new ZendLogLogger();
 $logger->addWriter($writer);
 $logger->debug(__METHOD__);

Sohel is right, it does not show your echo if you try to add to cart. You can try this one and check your log at var/log/addToCart.log
