How to Programmatically Add Product to Cart in Magento 2

 

Sometimes, Magento 2 store admin needs to prefill the shopping cart with a product whenever a user lands to the website. There are many uses of this functionality; for example, the admin may require to add a virtual product to cart whenever a particular product is added to the cart by a customer, the admin may want to give away the free product by default, the admin requires to integrate a custom system or he may require to send visitors directly to the checkout with the product in the cart.

Default Magento 2 doesn’t allow this. So, I’ve come up with a method to programmatically add product to cart in Magento 2.
