How to create product attribute in Magento 2.3 via declarative schema. I have tried below code but the input element is not visible on the form.

<?php



namespace RokanthemesUpdatesSetupPatchData;



use MagentoFrameworkSetupPatchDataPatchInterface;

use MagentoFrameworkSetupPatchPatchVersionInterface;

use MagentoFrameworkSetupModuleDataSetupInterface;

use MagentoCustomerModelCustomer;

use MagentoCustomerSetupCustomerSetupFactory;

use MagentoEavModelEntityAttributeSetFactory as AttributeSetFactory;

use MagentoFrameworkDBDdlTable;



class AddAttributes implements DataPatchInterface

{

    protected $_moduleDataSetup;

    protected $_customerSetupFactory;

    protected $_attributeSetFactory;



    public function __construct(

        ModuleDataSetupInterface $moduleDataSetup,

        CustomerSetupFactory $customerSetupFactory,

        AttributeSetFactory $attributeSetFactory

    )

    {

        $this->_moduleDataSetup = $moduleDataSetup;

        $this->_customerSetupFactory = $customerSetupFactory;

        $this->_attributeSetFactory = $attributeSetFactory;

    }



    public function apply()

    {

        $customerSetup = $this->_customerSetupFactory->create(['setup' => $this->_moduleDataSetup]);



        $customerEntity = $customerSetup->getEavConfig()->getEntityType(Customer::ENTITY);

        $attributeSetId = $customerEntity->getDefaultAttributeSetId();



        $attributeSet = $this->_attributeSetFactory->create();

        $attributeSet->getDefaultGroupId($attributeSetId);



        $customerSetup->addAttribute(Customer::ENTITY, 'news_from_date', array(

            'type' => Table::TYPE_DATE,

            'label' => 'New from date',

            'input' => 'date',

            'required' => 1,

            'type' => 'static',            

            'visible' => true

        ));

    }



    public function getAliases()

    {

        return ;

    }



    public static function getDependencies()

    {

        return [



        ];

    }

}

Thanks for the help.

Try this,

<?php                                                                 

 namespace Vendor_nameModuel_nameSetupPatchData;                        

 use MagentoCatalogSetupCategorySetup;                                   

 use MagentoCatalogSetupCategorySetupFactory;                            

 use MagentoFrameworkAppResourceConnection;                              

 use MagentoFrameworkSetupModuleDataSetupInterface;                      

 use MagentoFrameworkSetupPatchDataPatchInterface;                      

 use MagentoFrameworkSetupPatchPatchVersionInterface;                 

 class AddAttributes implements DataPatchInterface, PatchVersionInterface{

 private $moduleDataSetup;

 private $categorySetupFactory;

 public function __construct(

    ModuleDataSetupInterface $moduleDataSetup,

    CategorySetupFactory $categorySetupFactory

 ) {

    $this->moduleDataSetup = $moduleDataSetup;

    $this->categorySetupFactory = $categorySetupFactory;

 }



 public function apply()

 {

    /** @var CategorySetup $categorySetup */

    $categorySetup = $this->categorySetupFactory->create(['setup' => $this->moduleDataSetup]);



    $categorySetup->addAttribute(

        MagentoCatalogModelProduct::ENTITY,

        'custom_layout',

        [

            'type' => 'varchar',

            'label' => 'New Layout',

            'input' => 'date',

            'required' => false,

            'sort_order' => 50,

            'group' => 'General',

            'is_used_in_grid' => true,

            'is_visible_in_grid' => false,

            'is_filterable_in_grid' => false

        ]

    );

 }}
