I have some business logic after entering shipping address or select shipping address, for these, I override the _formRateRequest
and setRequest
methods from core class \Magento\Fedex\Model\Carrier
in my custom module, and my business logic is working. After successfully validated I need to show the custom block or custom message in shipping method section after shipping address entered or select.
But here I confusing how to start and where to start?
Any suggestions? on this.
