How To Create Custom Product Attribute Set From DataPatch Installer In Magento 2

How To Create Custom Product Attribute Set From DataPatch Installer In Magento 2- Here I am going to explain you how to create custom product attribute set from dataPatch installer.

If you want to create a custom product attribute set then create a file “AddCustomAttributeSet.php” in Vendor\CustomModule\Setup\Patch\Data and then add following code snippet.

<?php

namespace Vendor\ModuleName\Setup\Patch\Data;

use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Framework\Setup\Patch\DataPatchInterface;
use Magento\Eav\Model\Entity\Attribute\SetFactory as AttributeSetFactory;
use Magento\Catalog\Setup\CategorySetupFactory;

class AddCustomAttributeSet implements DataPatchInterface
{
    /**
     * @var ModuleDataSetupInterface
     */
    private $moduleDataSetup;

    /**
     * @var AttributeSetFactory
     */
    private $attributeSetFactory;

    /**
     * @var CategorySetupFactory
     */
    private $categorySetupFactory;

    /**
     * @param ModuleDataSetupInterface $moduleDataSetup
     * @param AttributeSetFactory $attributeSetFactory
     * @param CategorySetupFactory $categorySetupFactory
     */
    public function __construct(
        ModuleDataSetupInterface $moduleDataSetup,
        AttributeSetFactory $attributeSetFactory,
        CategorySetupFactory $categorySetupFactory
    ) {
        $this->moduleDataSetup = $moduleDataSetup;
        $this->attributeSetFactory = $attributeSetFactory;
        $this->categorySetupFactory = $categorySetupFactory;
    }

    /**
     * @inheritdoc
     */
    public function apply()
    {
        $setup = $this->moduleDataSetup;
        $setup->startSetup();
        $categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);
        $attributeSet = $this->attributeSetFactory->create();
        $entityTypeId = $categorySetup->getEntityTypeId(\Magento\Catalog\Model\Product::ENTITY);
        $attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId); // Default attribute set Id
        $data = [
            'attribute_set_name' => 'Custom_Product_attribute_set', // custom attribute set name
            'entity_type_id' => $entityTypeId,
            'sort_order' => 50,
        ];
        $attributeSet->setData($data);
        $attributeSet->validate();
        $attributeSet->save();
        $attributeSet->initFromSkeleton($attributeSetId)->save(); // based on default attribute set
    }

    /**
     * @inheritdoc
     */
    public static function getDependencies()
    {
        return [];
    }

    /**
     * @inheritdoc
     */
    public function getAliases()
    {
        return [];
    }
}

Now in this way you can create custom product attribute set.
