A secure and reliable payment gateway integration in Flutter using Ccavenue, allowing users to make seamless transactions within the app with ease. Ensure smooth online payments and enhance customer trust by incorporating Ccavenue payment gateway in your Flutter application.

CCavenue is a popular payment gateway that offers secure and convenient online payment solutions for businesses of all sizes. If you are a Flutter developer looking to integrate a payment gateway into your app, CCavenue is a great option to consider.

In this article, we will walk you through step-by-step instructions on how to integrate CCavenue payment gateway into a Flutter app. By the end of this tutorial, you will have a fully functional payment system that allows users to make payments securely and easily.

Before we dive into the integration process, make sure you have already set up a CCavenue account for your business. You will need your Merchant ID, Access Code, and Encryption Key to complete the integration.

Step 1: Add Dependencies

The first step is to add the necessary dependencies to your Flutter project. Open your pubspec.yaml file and add the following dependencies:

```yaml
dependencies:
ccavenue_flutter: ^1.0.0
```

Then, run 'flutter pub get' to install the dependencies.

Step 2: Initialize CCavenue Plugin

Next, you need to initialize the CCavenue plugin in your Flutter app. This involves setting up the Merchant ID, Access Code, Encryption Key, and other configurations. Here's how you can do this:

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
CCavenueFlutter.init(YOUR_MERCHANT_ID, YOUR_ACCESS_CODE, YOUR_ENCRYPTION_KEY);
return MaterialApp(
home: HomeScreen(),
);
}
}
```

Make sure to replace YOUR_MERCHANT_ID, YOUR_ACCESS_CODE, and YOUR_ENCRYPTION_KEY with your actual CCavenue credentials.

Step 3: Implement the Payment System

Now that you have initialized the CCavenue plugin, you can start implementing the payment system in your Flutter app. Let's create a simple example where users can enter their payment details and make a payment using CCavenue.

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

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

class _PaymentScreenState extends State {
TextEditingController amountController = TextEditingController();

@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Make a Payment'),
),
body: Column(
children: [
TextField(
controller: amountController,
decoration: InputDecoration(labelText: 'Enter Amount'),
),
RaisedButton(
onPressed: () {
CCavenueFlutter.makePayment(
amount: amountController.text,
orderId: ORDER_ID,
currency: INR,
callbackUrl: YOUR_CALLBACK_URL,
customersName: Customer Name,
customersEmail: customer@example.com,
customersMobile: 1234567890,
);
},
child: Text('Pay Now'),
),
],
),
);
}
}
```

In this example, we have created a PaymentScreen widget where users can enter the payment amount and click on a 'Pay Now' button to make a payment using CCavenue. The makePayment method from the CCavenue plugin is called with the necessary parameters such as amount, orderId, currency, callbackUrl, customersName, customersEmail, and customersMobile.

Step 4: Handle the Payment Response

After the user completes the payment process, CCavenue will redirect them to the callback URL specified in the makePayment method. You need to handle this callback URL in your Flutter app to process the payment response.

Here's how you can do this:

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
@override
void initState() {
CCavenueFlutter.setResponseHandler((Map response) {
String status = response['status'];
String orderId = response['orderId'];

if (status == 'success') {
// Payment successful
print('Payment successful for order $orderId');
} else if (status == 'failure') {
// Payment failed
print('Payment failed for order $orderId');
}
});
}

@override
Widget build(BuildContext context) {
return MaterialApp(
home: PaymentScreen(),
);
}
}
```

In this code snippet, we have set up a response handler using the setResponseHandler method from the CCavenue plugin. The response contains the status of the payment and the order ID. You can then handle the payment response accordingly based on the status.
