<type name="Magento\Catalog\Model\Layer"> <plugin name="LayerPlugin" type="Vendername\Modulename\Plugin\Layer"/> </type>

<type name="Magento\Catalog\Model\Layer">
<plugin name="LayerPlugin" type="Vendername\Modulename\Plugin\Layer"/>
</type>

2. The next step is to create Layer.php file in your module and paste below code in Vendername\Modulename\Plugin folder

<?php
namespace Vendername\Modulename\Plugin;

use Magento\Catalog\Api\CategoryRepositoryInterface;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Catalog\Model\ResourceModel\Product\Attribute\CollectionFactory as AttributeCollectionFactory;

class Layer
{
 /**
 * Product collections array
 *
 * @var array
 */
 protected $_productCollections = [];

 /**
 * Key which can be used for load/save aggregation data
 *
 * @var string
 */
 protected $_stateKey = null;

 /**
 * Core registry
 *
 * @var \Magento\Framework\Registry
 */
 protected $registry = null;

 /**
 * Store manager
 *
 * @var \Magento\Store\Model\StoreManagerInterface
 */
 protected $_storeManager;

 /**
 * Catalog product
 *
 * @var \Magento\Catalog\Model\ResourceModel\Product
 */
 protected $_catalogProduct;

 /**
 * Attribute collection factory
 *
 * @var AttributeCollectionFactory
 */
 protected $_attributeCollectionFactory;

 /**
 * Layer state factory
 *
 * @var \Magento\Catalog\Model\Layer\StateFactory
 */
 protected $_layerStateFactory;

 /**
 * @var \Magento\Catalog\Model\Layer\ItemCollectionProviderInterface
 */
 protected $collectionProvider;

 /**
 * @var \Magento\Catalog\Model\Layer\Category\StateKey
 */
 protected $stateKeyGenerator;

 /**
 * @var \Magento\Catalog\Model\Layer\Category\CollectionFilter
 */
 protected $collectionFilter;

 /**
 * @var CategoryRepositoryInterface
 */
 protected $categoryRepository;

 /**
 * @param Layer\ContextInterface $context
 * @param Layer\StateFactory $layerStateFactory
 * @param AttributeCollectionFactory $attributeCollectionFactory
 * @param \Magento\Catalog\Model\ResourceModel\Product $catalogProduct

 * @param \Magento\Framework\Registry $registry
 * @param CategoryRepositoryInterface $categoryRepository
 * @param array $data
 */

 \Magento\Catalog\Model\Layer\StateFactory $layerStateFactory,
 AttributeCollectionFactory $attributeCollectionFactory,
 \Magento\Catalog\Model\ResourceModel\Product $catalogProduct,
 \Magento\Store\Model\StoreManagerInterface $storeManager,

 array $data = []

 }
