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(),
    phone: '9979999799',
    amount: "10.00",
