I need to show configurable product highest price in frontend.

currently by default magento is loading lowest price.

please help me to solve this issue.

Tried by overriding

"MagentoConfigurableProductPricingPriceConfigurablePriceResolver"

My code :

class MaxConfigurablePrice
{
 protected $productRepository;
 protected $productFactory;
 protected $dataObjectHelper;
 protected $storeManager;
 protected $logFilePath = '/var/log/sub_debug.log';
public function __construct(
 MagentoCatalogApiProductRepositoryInterface $productRepository,
 MagentoCatalogApiDataProductInterfaceFactory $productFactory,
 MagentoFrameworkApiDataObjectHelper $dataObjectHelper,
 MagentoStoreModelStoreManagerInterface $storeManager
)

 $this->productFactory = $productFactory;
 $this->productRepository = $productRepository;
 $this->dataObjectHelper = $dataObjectHelper;
 $this->storeManager = $storeManager;


/**
 * @param MagentoFrameworkPricingSaleableInterface|MagentoCatalogModelProduct $subject
 * @param callable $proceed
 * @param MagentoFrameworkPricingSaleableInterface $product
 * @return float
 * @throws MagentoFrameworkExceptionLocalizedException
 */
public function aroundResolvePrice($subject, callable $proceed, MagentoFrameworkPricingSaleableInterface $product)

 // let the before hooks run.
 $returnValue = (float)$proceed($product);

 // and then we'll override with our logic
 $price = null;
 //get parent product id
 $parentId = $product['entity_id'];
 $childObj = $this->getChildProductObj($parentId);
 foreach($childObj as $childProduct)
 $productPrice = $childProduct->getPrice();
 $specialPrice = $childProduct->getData('special_price');

 $price = $price ? max($price, $productPrice) : $productPrice;

 // if the product with the highest price is also
 // the product that has a special price make sure
 // to display the special price (assuming it's valid)
 if ($price == $productPrice && isset($specialPrice)) 
 $now = date('Y-m-d H:i:s', time());
 $specialFromDate = $childProduct->getData('special_from_date');
 $specialToDate = $childProduct->getData('special_to_date');

 $this->log('FROM ' . __CLASS__ . '::' . __FUNCTION__ . ' AT LINE ' . __LINE__);
 $this->log('$productPrice: ' . var_export($productPrice, true));
 $this->log('$specialPrice: ' . var_export($specialPrice, true));
 $this->log('$specialFromDate: ' . var_export($specialFromDate, true));
 $this->log('$specialToDate: ' . var_export($specialToDate, true));
 $this->log('$now: ' . var_export($now, true));

 // $this->log('child product debug: ' . print_r($childProduct->debug(), true));


 switch (true) 
 case (isset($specialFromDate) && isset($specialToDate)):
 if (($now > $specialFromDate) && ($now < $specialToDate)) 
 $price = $specialPrice;

 $price = $specialPrice;
 
 break;

 case (!isset($specialFromDate) && !isset($specialToDate)):
 $price = $specialPrice;
 break;

 default:
 // do nothing...leave $price as it is
 break;
 
 
 

 $this->log('FROM ' . __CLASS__ . '::' . __FUNCTION__ . ' AT LINE ' . __LINE__);
 $this->log('returned $price: ' . var_export($price, true));

 return $price;
