          $this->_objectManager = $objectManager;
          $this->logger = $logger;
          $this->productFactory = $productFactory;

     }

     public function execute(\Magento\Framework\Event\Observer $observer)
     {  
          $order = $observer->getEvent()->getOrder();
          $order_id = $order->getIncrementId();
          $customerfirstname = $order->getCustomerFirstname();
          $customerlastname = $order->getCustomerLastname();
    
          $filepath = 'export/'.$order_id.'.csv';
          $this->directory->create('export');
          $stream = $this->directory->openFile($filepath, 'w+');
          $stream->lock();

          $header = ['Order Id', 'Customer FirstName', 'Customer LastName'];
          $stream->writeCsv($header);
        
          $data[] = $order_id;
          $data[] = $customerfirstname;
