use Magento\Bundle\Api\ProductLinkManagementInterface;

class ChildrenItem
     * @var LoggerInterface
    private $logger;

     * @var ProductLinkManagementInterface
    private $productLinkManagement;

    public function __construct(
        LoggerInterface $logger,
        ProductLinkManagementInterface $productLinkManagement
    ) {
        $this->logger = $logger;
        $this->productLinkManagement = $productLinkManagement;

     * Get all children items of bundle product
     * @return LinkInterface[]
    public function getChildrenItems()
        $sku = '24-WG080'; // Dynamic SKU
        try {
            $items = $this->productLinkManagement->getChildren($sku);
        } catch (Exception $exception) {
            throw new Exception($exception->getMessage());
