namespace VendorModuleBlockAdminhtmlOrderView;<br />
class customMessage extends MagentoBackendBlockTemplate<br />
{ // Here you can fetch order detail if you want to display in order information as an extra detail<br />
}

namespace VendorModuleBlockAdminhtmlOrderView;

class customMessage extends MagentoBackendBlockTemplate

// Here you can fetch order detail if you want to display in order information as an extra detail

2. Now, create customMessage.php at Vendor/Module/Block/Adminhtml/Order/View/

<h3>This order contains gift</h3>

Create sales_order_view.xml at Vendor/Module/view/adminhtml/layout/
