Usage #

Add mypay_flutter as a dependency in your pubspec.yaml file:

dependencies:
mypay_flutter: ^1.0.1
copied to clipboard

Import the package in your Dart code:

import 'package:mypay_flutter/mypay_flutter.dart';

Create an instance of MyPayConfig with your payment information:

The MyPayConfig class holds the configuration details for the payment gateway. Pass an instance of
MyPayConfig to the payment() method of the MyPay class to initiate the payment process.
final config = MyPayConfig(
amount: 2000,
environment: MyPayEnvironment.dev,
orderId: "QWE-SEW-SFES-QXZS",
merchantId: "CAFEQ",
userName: "username1",
password: "decryptedPassword",
returnUrl: "https://mypay.com.np");

copied to clipboard

Initialize the payment by calling MyPay.payment() method:

MyPay.payment(
context,
config: config,
apiKey: "APIKEY123",
onSuccess: (MyPaySuccessResult successResponse) {},
onFailure: (MyPayFailureResult failureResponse) {},
onCancel: (MyPayCancelResult cancelResponse) {},
);

copied to clipboard

Check the payment result:

Once the payment is finalized, the plugin payment function provides either
an instance of MyPaySuccessResult or MyPayFailureResult based on the outcome.
In the event of a successful payment, the onSuccess parameter is triggered,
allowing the user to execute desired actions. If the user cancels the payment,
the onCancel parameter is triggered, providing an opportunity to take appropriate
actions. Similarly, if the payment fails, the onFailure parameter is triggered,
enabling the user to handle the situation accordingly.
MyPay.payment(
context,
config: config,
apiKey: "APIKEY123",
onSuccess: (MyPaySuccessResult successResponse) {
// Perform Server Verification
},
onFailure: (MyPayFailureResult failureResponse) {
// What to do on failure?
},
onCancel: (MyPayCancelResult cancelResponse) {
// User manually cancelled the transaction
},
);

Dev/Live Mode #
MyPayConfig supports both dev and live mode. For live mode, use the MyPayEnvironment.live
value in environment parameter in MyPayConfig, and for dev mode, use the MyPayEnvironment.dev
value in environment parameter in MyPayConfig. Here's an example of using the dev mode:
final config = MyPayConfig(
amount: 2000,
environment: MyPayEnvironment.dev,
orderId: "QWE-SEW-SFES-QXZS",
merchantId: "CAFEQ",
userName: "username1",
password: "decryptedPassword",
returnUrl: "https://mypay.com.np");
