Inject the StockRegistryInterface interface in your custom block:

 * @var \Magento\CatalogInventory\Api\StockRegistryInterface
private $stockRegistry;

 * Constructor for DI.
 * @param \Magento\CatalogInventory\Api\StockRegistryInterface $stockRegistry
public function __construct(
    \Magento\CatalogInventory\Api\StockRegistryInterface $stockRegistry
) {
    $this->stockRegistry = $stockRegistry;

 * Get the product stock data and methods.
 * @return \Magento\CatalogInventory\Api\StockRegistryInterface

public function getStockRegistry()
    return $this->stockRegistry;

Use below code to get the stock details like product qty, availability etc:

$stockRegistry = $block->getStockRegistry();

/** @var \Magento\Catalog\Model\Product $product */
$product = your product object..

// Get stock data for given product.
$productStock = $stockRegistry->getStockItem($product->getId());

// Get quantity of product.
$productQty = $productStock->getQty();

You also asked for minimum qty, do you want to get minimum allowed qty in cart or you mean it to other qty?


You get data of stock quantity:

  $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
  $productStockObj = $objectManager->get('Magento\CatalogInventory\Api\StockRegistryInterface')->getStockItem($productId);
