@override
void initState() {
  _razorpay = Razorpay();
  _razorpay.initilizeSDK(key);
  _razorpay.on(Razorpay.EVENT_PAYMENT_SUCCESS, _handlePaymentSuccess);
  _razorpay.on(Razorpay.EVENT_PAYMENT_ERROR, _handlePaymentError);
}

void _handlePaymentSuccess(Map<dynamic, dynamic> response) {
  print('Payment Success Response : $response');
}

void _handlePaymentError(Map<dynamic, dynamic> response) {
  print('Payment Error Response : $response');
}

Error Codes

The error codes have been exposed as integers by the Razorpay class. The error code is available as the code field of the PaymentFailureResponse instance passed to the callback.
