I am new in magento module development. I was searching for something similar to this
https://www.mageplaza.com/devdocs/how-add-custom-discount-magento-2.html
I just editied the code in step 2 to meet my requirements. The subtotal and grand total is correct but Custom Discount always appears $10
I tried to edit the function in step 4
getCustomDiscount : function(){
return '$10';
}
I tried to change the value and flushed magento cache but the same value keeps showing ($10). Any suggestion please?
