A Flutter plugin for integrating Razorpay's payment gateway into your mobile app with ease. Simplify the process of accepting online payments and managing transactions seamlessly.
Flutter is a popular open-source framework that allows developers to build cross-platform mobile applications with ease. One of the main advantages of using Flutter is its ability to create beautiful and highly functional user interfaces. In addition to its user-friendly interface design capabilities, Flutter also supports integration with various payment gateways, such as Razorpay.
Razorpay is a leading payment gateway in India that allows businesses to accept online payments seamlessly. By integrating Razorpay with your Flutter application, you can provide your customers with a secure and convenient way to make payments for goods and services.
In this article, we will walk you through a step-by-step guide on how to integrate Razorpay with your Flutter application. By the end of this tutorial, you will have a fully functional payment gateway integrated into your Flutter app.
Step 1: Create a Razorpay Account
Before you can start integrating Razorpay with your Flutter application, you will need to create a Razorpay account. To do this, simply go to the Razorpay website and sign up for an account. Once you have created an account, you will be able to access the Razorpay dashboard, where you can generate API keys and other necessary credentials for integration.
Step 2: Install the Razorpay Flutter Plugin
To integrate Razorpay with your Flutter application, you will need to install the Razorpay Flutter plugin. This plugin provides all the necessary tools and functions for seamless integration with Razorpay's payment gateway.
To install the plugin, open your pubspec.yaml file and add the following dependency:
```yaml
dependencies:
razorpay_flutter: ^1.2.4
```
Once you have added the dependency, run 'flutter pub get' in your terminal to install the plugin.
Step 3: Set Up Razorpay credentials
Next, you will need to set up your Razorpay credentials in your Flutter application. To do this, go to the Razorpay dashboard and generate API keys for your account. You will need to copy the API key and API secret key and add them to your Flutter application.
In your main.dart file, initialize the Razorpay plugin with your API key and API secret key:
```dart
import 'package:razorpay_flutter/razorpay_flutter.dart';
var razorpay = new Razorpay();
razorpay.on(Razorpay.EVENT_PAYMENT_SUCCESS, handlerPaymentSuccess);
razorpay.on(Razorpay.EVENT_PAYMENT_ERROR, handlerPaymentError);
razorpay.on(Razorpay.EVENT_EXTERNAL_WALLET, handlerExternalWallet);
void handlerPaymentSuccess(PaymentSuccessResponse response) {
print(Payment success);
}
void handlerPaymentError(PaymentFailureResponse response) {
print(Payment error);
}
void handlerExternalWallet(ExternalWalletResponse response) {
print(External wallet);
}
```
Step 4: Create a Payment Function
Now that you have set up your Razorpay credentials, you can create a function to initiate payments in your Flutter application. This function will trigger the Razorpay payment gateway and allow users to make payments for goods and services.
```dart
void startPayment() {
var options = {
'key': 'YOUR_API_KEY',
'amount': 100000, // amount in the smallest currency unit
'name': 'Flutter Example',
'description': 'Payment for the Flutter Razorpay example',
'prefill': {'contact': '1234567890', 'email': 'example@example.com'},
'external': {
'wallets': ['paytm']
}
};
try {
razorpay.open(options);
} catch (e) {
print(e);
}
}
```
Step 5: Add a Button to Trigger Payments
To allow users to make payments, you can add a button to your Flutter application that triggers the payment function when clicked. Simply add a RaisedButton widget to your app and call the startPayment function on onPressed:
```dart
RaisedButton(
onPressed: () {
startPayment();
},
child: Text('Pay Now'),
),
```
Step 6: Handle Payment Callbacks
Finally, you will need to handle payment callbacks in your Flutter application. When a payment is successful, the handlerPaymentSuccess function will be triggered. You can use this function to update your UI or perform any other necessary actions.
```dart
void handlerPaymentSuccess(PaymentSuccessResponse response) {
print(Payment success);
// Add code to handle successful payment
}
```
And that's it! You have successfully integrated Razorpay with your Flutter application. Users can now make payments seamlessly using Razorpay's payment gateway.
In conclusion, integrating Razorpay with your Flutter application is a straightforward process that can greatly enhance the functionality of your app. By following the steps outlined in this article, you can create a secure and convenient payment experience for your users. Keep in mind that this is just a basic example of integrating Razorpay with Flutter, and you can further customize and optimize the integration to suit your specific needs. Happy coding!
