eSewa Flutter

A Flutter plugin for integrating eSewa payment gateway into your Flutter app.

Usage

1. Add esewa_flutter as a dependency in your pubspec.yaml file:

dependencies:
  esewa_flutter: ^1.0.0

2. Import the package in your Dart code:

import 'package:esewa_flutter/esewa_flutter.dart';

3. Create an instance of ESewaConfig with your payment information:

The ESewaConfig class holds the configuration details for the payment gateway. Pass an instance of ESewaConfig to the init() method of the Esewa class to initiate the payment process.

final config = ESewaConfig.live(
  amt: 100,
  scd: 'merchant_id',
  pid: 'product_id',
  su: 'https://success.com.np',
  fu: 'https://failure.com.np',
);

4. Initialize the payment by calling Esewa.init() method:

final result = await Esewa.i.init(
  context: context,
  eSewaConfig: config,
);

5. Check the payment result:

After the payment is completed or cancelled by the user, the plugin returns an instance of EsewaPaymentResult. If the payment was successful, hasData will be true and you can access the EsewaPaymentResponse object using data. If the payment was unsuccessful, hasError will be true and you can access the error message using error.

if (result.hasData) {
  // Payment successful
  final response = result.data!;
  print('Payment successful. Ref ID: ${response.refId}');
} else {
  // Payment failed or cancelled
  final error = result.error!;
  print('Payment failed or cancelled. Error: $error');
}

Dev/Live Mode

ESewaConfig supports both dev and live mode. For live mode, use the ESewaConfig.live() constructor, and for dev mode, use the ESewaConfig.dev() constructor. Here's an example of using the dev mode:

final config = ESewaConfig.dev(
  amt: 100,
  scd: 'merchant_id',
  pid: 'product_id',
  su: 'https://success.com.np',
  fu: 'https://failure.com.np',
);
