This is just copy of file vendor/magento/module-catalog/Block/Product/NewProduct.php
2) Created file app/design/frontend/{vendor-name}/{them-name}/Magento_Catalog/templates/product/special.phtml
<?php echo "My Special Product Block"?>
3) added cms content in home page
<div class="special-product">{{block class="Magento\Catalog\Block\Product\Special" template="Magento_Catalog::product/special.phtml" }}</div>
Now i am getting error
Error filtering template: Recoverable Error: Argument 1 passed to Magento\Catalog\Block\Product\Special::__construct() must be an instance of Magento\Catalog\Block\Product\Context, instance of Magento\Framework\ObjectManager\ObjectManager given, called in /www/magento2/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 93 and defined in /www/magento2/app/code/Magento/Catalog/Block/Product/Special.php on line 57
Can anyone suggest me what is wrong here ?
