An authorization_url is returned - your backend server should send this to the front end/client to checkout.
NB: Please ensure to set your redirect url when initialising the paystack transaction. #
Checkout/Payment
The authorization_url sent from your backend server is used as the only parameter to Paystack Standard interface.
The PaystackStandard.checkout method returns type CheckoutResponse which contains a success - bool, and the transaction reference.

PaystackStandard(context).checkout(checkoutUrl: "<authorization_url>").then((response){
// here check for success - verify transaction status with your backend server
});
