How to get coupon information?

[royhoglass]

Hi all, I am new to magento 2.

I have the coupon code and trying to use \Magento\SalesRule\Model\Coupon $coupon but no luck.

I put this to construct "use \Magento\SalesRule\Model\Coupon $coupon"

error message:

Fatal error: Uncaught TypeError: Argument 1 passed to Magento\SalesRule\Model\CouponRepository::__construct() must be an instance of Magento\SalesRule\Model\CouponFactory, none given, called in /var/www/html/magento/app/code/

can someone please help?
