In magento 2.2.7 when AddToCart button is clicked i need to validate Delivery Postcode field.Only if the customer enter the correct post code the product should added to the cart.
The Delivery Postcode is a separate extension. Inside the extension i wrote before plugin (using beforeAddProduct class)and try to get the postcode parameter but i am unable to do so, but i can able to get the product related parameter.For ex. product quantity i can able get. Can you please guide me how to get the postcode value inside the plugin?
