This Flutter plugin allows for seamless integration of the Ccavenue payment gateway, providing a secure and reliable payment processing solution for mobile applications. With easy-to-use functionalities and robust documentation, developers can quickly implement Ccavenue payment gateway in their Flutter projects with this open-source plugin on Github.

Flutter is a popular open-source framework for building cross-platform applications. With its flexibility and ease of use, Flutter has gained momentum in the development community. One common feature that developers often need to incorporate into their applications is payment gateway integration. This is where Ccavenue, a leading payment gateway provider in India, comes into play.

Ccavenue offers a seamless and secure payment processing solution that can be integrated into Flutter applications with ease. In this article, we will walk you through the process of integrating Ccavenue payment gateway into your Flutter project on GitHub.

Step 1: Set Up Your Ccavenue Account

Before you can integrate Ccavenue into your Flutter application, you need to create an account with Ccavenue. Visit their website and sign up for an account. Once you have registered and logged in, you will have access to your merchant ID, access code, and encryption key. These credentials are essential for integrating Ccavenue into your Flutter project.

Step 2: Install Dependencies

In your Flutter project, open the pubspec.yaml file and add the following dependencies:

```
dependencies:
flutter:
sdk: flutter
ccavenue: ^1.0.0
```

Save the file and run `flutter pub get` in your terminal to install the ccavenue package.

Step 3: Implement Payment Gateway Integration

To implement the Ccavenue payment gateway in your Flutter project, create a new Dart file named 'payment_screen.dart'. In this file, import the necessary packages:

```dart
import 'package:flutter/material.dart';
import 'package:ccavenue/ccavenue.dart';
```

Next, create a StatefulWidget called PaymentScreen:

```dart
class PaymentScreen extends StatefulWidget {
@override
_PaymentScreenState createState() => _PaymentScreenState();
}

class _PaymentScreenState extends State {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Payment Gateway Integration'),
),
body: Center(
child: RaisedButton(
child: Text('Make Payment'),
onPressed: () {
_makePayment();
},
),
),
);
}

void _makePayment() {
// Implement Ccavenue payment logic here
}
}
```

In the `_makePayment` method, you will write the code to initiate the payment process using the Ccavenue SDK. This involves creating a payment request with your merchant ID, access code, encryption key, and other relevant details.

Step 4: Initialize Ccavenue SDK

To initialize the Ccavenue SDK, you need to call the `initialize` method with your Ccavenue credentials. Add the following code to the `_makePayment` method:

```dart
void _makePayment() {
Ccavenue.initialize(
merchantId: 'YOUR_MERCHANT_ID',
accessCode: 'YOUR_ACCESS_CODE',
encryptionKey: 'YOUR_ENCRYPTION_KEY',
orderID: 'YOUR_ORDER_ID',
amount: '100',
currency: 'INR',
redirectURL: 'YOUR_REDIRECT_URL',
);
}
```

Make sure to replace the placeholders with your actual Ccavenue credentials. The `orderID` and `redirectURL` are optional parameters that you can customize based on your requirements.

Step 5: Handle Payment Response

Once the payment request is initiated, the user will be redirected to the Ccavenue payment gateway to complete the transaction. After the transaction is completed, the user will be redirected back to your application using the `redirectURL` specified in the payment request.

To handle the payment response, add the following code to the `main.dart` file:

```dart
import 'package:flutter/material.dart';
import 'package:ccavenue/ccavenue.dart';
import 'payment_screen.dart';

void main() {
runApp(MaterialApp(
home: PaymentScreen(),
onGenerateRoute: (settings) {
if (settings.name == '/payment_response') {
final args = settings.arguments as Map;
Ccavenue.handlePaymentResponse(args);
}
},
));
}
```

In this code snippet, we define a route handler for `/payment_response` that calls the `handlePaymentResponse` method from the Ccavenue SDK. This method parses the payment response data and provides the necessary information about the transaction status.

Step 6: Test the Integration

Once you have integrated Ccavenue into your Flutter project, it's time to test the payment gateway integration. Run your Flutter application on a device or simulator and navigate to the payment screen. Click on the 'Make Payment' button to initiate the payment process.

You will be redirected to the Ccavenue payment gateway where you can enter your payment details and complete the transaction. After the payment is processed, you will be redirected back to your Flutter application with the payment response data.
