   <?php namespace Vendor\Module\Plugin\Checkout\Block\Cart\Item; use Magento\Catalog\Model\Product\Configuration\Item\ItemResolverInterface; use Magento\CatalogInventory\Helper\Data; use Magento\CatalogInventory\Model\Stock; use Magento\Framework\Pricing\PriceCurrencyInterface; use Magento\Framework\View\Element\Message\InterpretationStrategyInterface; class Renderer extends \Magento\Checkout\Block\Cart\Item\Renderer { protected $stockRegistry; public function __construct( \Magento\Framework\View\Element\Template\Context $context, \Magento\Catalog\Helper\Product\Configuration $productConfig, \Magento\Checkout\Model\Session $checkoutSession, \Magento\Catalog\Block\Product\ImageBuilder $imageBuilder, \Magento\Framework\Url\Helper\Data $urlHelper, \Magento\Framework\Message\ManagerInterface $messageManager, PriceCurrencyInterface $priceCurrency, \Magento\Framework\Module\Manager $moduleManager, InterpretationStrategyInterface $messageInterpretationStrategy, array $data = [], ItemResolverInterface $itemResolver = null, \Magento\CatalogInventory\Api\StockRegistryInterface $stockRegistry ) { parent::__construct($context, $productConfig, $checkoutSession, $imageBuilder, $urlHelper, $messageManager, $priceCurrency, $moduleManager, $messageInterpretationStrategy, $data, $itemResolver); $this->stockRegistry = $stockRegistry; } public function isProductAvailable() { $quoteItem = $this->getItem(); $product = $this->getProduct(); /* @var \Magento\CatalogInventory\Api\Data\StockStatusInterface $stockStatus */ $stockStatus = $this->stockRegistry->getStockStatus($product->getId(), $product->getStore()->getWebsiteId()); /* @var \Magento\CatalogInventory\Api\Data\StockStatusInterface $parentStockStatus */ $parentStockStatus = false; /** * Check if product in stock. For composite products check base (parent) item stock status */ if ($quoteItem->getParentItem()) { $product = $quoteItem->getParentItem()->getProduct(); $parentStockStatus = $this->stockRegistry->getStockStatus( $product->getId(), $product->getStore()->getWebsiteId() ); } if ($stockStatus) { if ($stockStatus->getStockStatus() === Stock::STOCK_OUT_OF_STOCK || $parentStockStatus && $parentStockStatus->getStockStatus() == Stock::STOCK_OUT_OF_STOCK ) { return false; } else { return true; } } } }

   <?php if ($block->isProductAvailable()): ?>     <div class="stock available  col-lg-4" title="<?php /* @escapeNotVerified */ echo __('Availability') ?>">         <i class="fa fa-check-circle" aria-hidden="true"></i>         <span><?php /* @escapeNotVerified */ echo __('In Stock') ?></span>     </div> <?php else: ?>     <div class="stock unavailable  col-lg-4" title="<?php /* @escapeNotVerified */ echo __('Availability') ?>">         <span><?php /* @escapeNotVerified */ echo __('Out of Stock') ?></span>     </div> <?php endif; ?>
