     */

     */
    protected $_convertOrder;

    /**

     */
    protected $_shipmentNotifier;

    /**
     * @param Context                                     $context
     * @param \Magento\Sales\Api\OrderRepositoryInterface $orderRepository
     * @param \Magento\Sales\Model\Convert\Order          $convertOrder
     * @param \Magento\Shipping\Model\ShipmentNotifier    $shipmentNotifier
     */
    public function __construct(
        Context $context,
        \Magento\Sales\Api\OrderRepositoryInterface $orderRepository,
        \Magento\Sales\Model\Convert\Order $convertOrder,
        \Magento\Shipping\Model\ShipmentNotifier $shipmentNotifier
    ) {
        $this->_orderRepository = $orderRepository;
        $this->_convertOrder = $convertOrder;
        $this->_shipmentNotifier = $shipmentNotifier;
        parent::__construct($context);
    }

    /**
     * Demo Order Create Shipment Controller
     */
    public function execute()
    {
        $orderId = 1000001;
        $order = $this->_orderRepository->get($orderId);

        // check order can ship or not
        if (!$order->canShip()) {
            throw new \Magento\Framework\Exception\LocalizedException(
            __('You can't create the Shipment of this order.') );
        }

        $orderShipment = $this->_convertOrder->toShipment($order);

        foreach ($order->getAllItems() AS $orderItem) {

         // Check virtual item and item Quantity
         if (!$orderItem->getQtyToShip() || $orderItem->getIsVirtual()) {
            continue;
         }

         $qty = $orderItem->getQtyToShip();
         $shipmentItem = $convertOrder->itemToShipmentItem($orderItem)->setQty($qty);

         $orderShipment->addItem($shipmentItem);
        }

        $orderShipment->register();
        $orderShipment->getOrder()->setIsInProcess(true);
        try {

            // Save created Shipment
            $orderShipment->save();
            $orderShipment->getOrder()->save();

            // Send Shipment Email
            $this->_shipmentNotifier->notify($orderShipment);
            $orderShipment->save();
        } catch (\Exception $e) {
            throw new \Magento\Framework\Exception\LocalizedException(
            __($e->getMessage())
            );
