A flutter package for sagepay checkout

Flutter plugin for sagepay SDK

Getting started

To use this plugin, add sagepay as a dependency in your pubspec.yaml file.

How to Use

This plugin uses two APIs

1. Create a SagePay instance by calling the constructor SagePay. The constructor accepts a required instance of the following: context, business, reference, callbackUrl, amount, token It returns an instance of SagePay which we then call the async method .chargeTransaction() on.

import 'package:sagepay/sagepay.dart';

final sagePay = SagePay(
   context: context,
   amount: 100,
   reference: "{{randomly generated string}}",
   callbackUrl: "{{call back url}}",
   token: "{{Secret Key}}",
   business: Business(name: "{{business name}}", email: "{{business email}}"),
   paymentMethod: 'card,transfer',
   metadata: {
      "name":"Ladenifer Jada",
      "email":"[e-mail]"
   }
);

PaymentResponse? response = await sagePay.chargeTransaction();

2. Handle the response Calling the .chargeTransaction() method returns a Future of PaymentResponse which we await for the actual response as seen above.

PaymentResponse? response = await sagePay.chargeTransaction();

if (response != null) {
  if(response.success!) {
    //handle success response 
  } else {
    //Handle not successful 
  }
} else {
  //User cancelled checkout
}
