Getting Started #

This flutter plugin is a wrapper on PayU Hosted.

Prerequisites #

Learn about the PayU Payment Flow.
Sign up for a PayU Account and generate the API Keys from the PayU Dashboard. Using the Test keys helps simulate a sandbox environment. No actual monetary transaction happens when using the Test keys. Use Live keys once you have thoroughly tested the application and are ready to go live.

Installation #

This plugin is available on Pub: https://pub.dev/packages/payu_web_checkout

Add this to dependencies in your app's pubspec.yaml

payu_web_checkout: ^1.0.2

Usage #

Sample code to integrate can be found in example/lib/main.dart.

Import package

import 'package:payu_web_checkout/payu_web_checkout.dart';

Create PayUWebCheckout instance

_payUWebCheckout = PayUWebCheckout();

Attach event listeners

The plugin uses event-based communication, and emits events when payment fails or succeeds.

The event names are exposed via the constants EVENT_PAYMENT_SUCCESS and EVENT_PAYMENT_ERROR from the PayUWebCheckout class.

Use the on(String event, Function handler) method on the PayUWebCheckout instance to attach event listeners.

_payUWebCheckout.on(PayUWebCheckout.EVENT_PAYMENT_SUCCESS, _handlePaymentSuccess);
_payUWebCheckout.on(PayUWebCheckout.EVENT_PAYMENT_ERROR, _handlePaymentError);

The handlers would be defined somewhere as


void _handlePaymentSuccess(PaymentSuccessResponse response) {
  // Do something when payment succeeds
}

void _handlePaymentError(PaymentFailureResponse response) {
  // Do something when payment fails
}

To clear event listeners, use the clear method on the PayUWebCheckout instance.

_payUWebCheckout.clear(); // Removes all listeners

Setup options

  var payuWebCheckoutModel = PayuWebCheckoutModel(
    key: "<YOUR_KEY_HERE>",
    salt: "<YOUR_SALT_HERE>",
    txnId: DateTime.now().millisecondsSinceEpoch.toString(),
