Flutter plugin for Razorpay SDK.
This flutter plugin is a wrapper around our Android and iOS SDKs.
The following documentation is only focused on the wrapper around our native Android and iOS SDKs. To know more about our SDKs and how to link them within the projects, refer to the following documentation:
Android: https://razorpay.com/docs/checkout/android/
iOS: https://razorpay.com/docs/ios/
To know more about Razorpay payment flow and steps involved, read up here: https://razorpay.com/docs/
- Learn about the Razorpay Payment Flow.
- Sign up for a Razorpay Account and generate the API Keys from the Razorpay 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.
This plugin is available on Pub: https://pub.dev/packages/razorpay_flutter
Add this to dependencies in your app's pubspec.yaml
razorpay_flutter: ^1.3.5Note for Android: Make sure that the minimum API level for your app is 19 or higher.
If you are using proguard for your builds, you need to add following lines to proguard files
-keepattributes *Annotation*
-dontwarn com.razorpay.**
-keep class com.razorpay.** {*;}
-optimizations !method/inlining/
-keepclasseswithmembers class * {
public void onPayment*(...);
}
Follow this for more details.
Note for iOS: Make sure that the minimum deployment target for your app is iOS 10.0 or higher. Also, don't forget to enable bitcode for your project.
Run flutter packages get in the root directory of your app.
Sample code to integrate can be found in example/lib/main.dart.
import 'package:razorpay_flutter/razorpay_flutter.dart';_razorpay = Razorpay();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, EVENT_PAYMENT_ERROR and EVENT_EXTERNAL_WALLET from the Razorpay class.
Use the on(String event, Function handler) method on the Razorpay instance to attach event listeners.
_razorpay.on(Razorpay.EVENT_PAYMENT_SUCCESS, _handlePaymentSuccess);
_razorpay.on(Razorpay.EVENT_PAYMENT_ERROR, _handlePaymentError);
_razorpay.on(Razorpay.EVENT_EXTERNAL_WALLET, _handleExternalWallet);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
}
void _handleExternalWallet(ExternalWalletResponse response) {
// Do something when an external wallet was selected
}To clear event listeners, use the clear method on the Razorpay instance.
_razorpay.clear(); // Removes all listenersvar options = {
'key': '<YOUR_KEY_HERE>',
'amount': 100,
'name': 'Acme Corp.',
'description': 'Fine T-Shirt',
'prefill': {
'contact': '8888888888',
'email': '[email protected]'
}
};A detailed list of options can be found here.
_razorpay.open(options);Open ios/Podfile and find this section:
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
end
end
endSet config.build_settings['ENABLE_BITCODE'] = 'YES'.
Add the following line below config.build_settings['ENABLE_BITCODE'] = 'YES':
config.build_settings['SWIFT_VERSION'] = '5.0'
Specs satisfying the `razorpay_flutter (from
`.symlinks/plugins/razorpay_flutter/ios`)` dependency were found, but they
required a higher minimum deployment target.
This is due to your minimum deployment target being less than iOS 10.0. To change this, open ios/Podfile in your project and add/uncomment this line at the top:
# platform :ios, '9.0'and change it to
platform :ios, '10.0'and run pod install again in the ios directory.
Add use_frameworks! in ios/Podfile and run pod install again in the ios directory.
Gradle build fails with Error: uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [:razorpay_flutter]
This is due to your Android minimum SDK version being less than 19. To change this, open android/app/build.gradle, find minSdkVersion in defaultConfig and set it to at least 19.
We export a class Razorpay from package:razorpay_flutter/razorpay_flutter.dart. Check if your code is redeclaring the Razorpay class.

Check the signatures of the callbacks for payment events. They should match the ones described here.
