I am trying to get details for payment made and update the details in the database subscription table, I am using Razorpay, Razorpay provides methods to handle different events that occurs. I want to send post request to the rest-api, Unfortunately, Razorpay's Payment success Event handler method is not calling my _subscription() function.
Here is my payment code.
import 'dart:convert';
import 'package:cached_network_image/cached_network_image.dart';
import 'package:flutter/material.dart';
import 'package:flutter_spinkit/flutter_spinkit.dart';
import 'package:razorpay_flutter/razorpay_flutter.dart';
import 'package:tneos_eduloution/network_utils/api.dart';
import 'package:flutter/services.dart';
import 'package:fluttertoast/fluttertoast.dart';
class Payment extends StatefulWidget {
final int amount;
final int categoryId;
final int userId;
final String name;
final String image;
final int packageClass;
final String subject;
final String board;
Payment(this.amount, this.categoryId, this.userId, this.name, this.image, this.packageClass, this.subject, this.board);
@override
_PaymentState createState() => _PaymentState(this.amount, this.categoryId, this.categoryId, this.name, this.image, this.packageClass, this.subject, this.board);
}
class _PaymentState extends State<Payment> {
static const platform = const MethodChannel("razorpay_flutter");
int amount;
int categoryId;
int userId;
String name;
String image;
int packageClass;
String subject;
String board;
Razorpay _razorpay;
// var orderId;
// var razorpayId;
_PaymentState(this.amount, this.categoryId, this.userId, this.name,
this.image, this.packageClass, this.subject, this.board);
@override
Widget build(BuildContext context) {
return Scaffold(
// Code ....
body: Container(
// Code ....
Expanded(
flex: 2,
child: Padding(
padding: const EdgeInsets.all(24.0),
child: RaisedButton(

fontSize: 32,

letterSpacing: 2,
))
],
),
onPressed: () {
openCheckout();
}),
),
// Code....
}
@override
void initState() {
super.initState();
_razorpay = Razorpay();
_razorpay.on(Razorpay.EVENT_PAYMENT_SUCCESS, _handlePaymentSuccess);
_razorpay.on(Razorpay.EVENT_PAYMENT_ERROR, _handlePaymentError);
_razorpay.on(Razorpay.EVENT_EXTERNAL_WALLET, _handleExternalWallet);
}
@override
void dispose() {
super.dispose();
_razorpay.clear();
}
void openCheckout() async {
var options = {
'key': 'rzp_test_YbFME7OVSi2Kvx',
'amount': amount * 100,
'name': name,
'image': 'https://tneos.in/app-assets/img/core-img/favicon.ico',
'description': 'Buy the Course to get access for all live classes',
'prefill': {'contact': '', 'email': ''},
'external': {
'wallets': ['paytm']
}
};
try {
_razorpay.open(options);
} catch (e) {
debugPrint(e);
}
}
Future<void> _handlePaymentSuccess(PaymentSuccessResponse response) async {
// orderId = 12123;
// razorpayId = response.paymentId;
_subscription();
Fluttertoast.showToast(
msg: "SUCCESS: " + response.paymentId, timeInSecForIosWeb: 4);
}
void _handlePaymentError(PaymentFailureResponse response) {
Fluttertoast.showToast(
msg: "ERROR: " + response.code.toString() + " - " + response.message,
timeInSecForIosWeb: 4);
}
void _handleExternalWallet(ExternalWalletResponse response) {
Fluttertoast.showToast(
msg: "EXTERNAL_WALLET: " + response.walletName, timeInSecForIosWeb: 4);
}
void _subscription() async {
var data = {
'name': name,
'amount': amount,
// 'order_id': orderId,
// 'razorpay_id': razorpayId,
'category_id': categoryId,
'user_id': userId};
var res = await Network().authData(data, '/subscription');
var body = json.decode(res.body);
if (body['success']) {
print('success');
} else {
print('failure');
}
}
}
authData comes from network class
import 'dart:convert';
import 'package:http/http.dart' as http;
import 'package:shared_preferences/shared_preferences.dart';
class Network {
final String _url = 'http://10.0.2.2:8000/api/v1';
//if you are using android studio emulator, change localhost to 10.0.2.2
var token;
_getToken() async {
SharedPreferences localStorage = await SharedPreferences.getInstance();
token = jsonDecode(localStorage.getString('token'))['token'];
}
authData(data, apiUrl) async {
var fullUrl = _url + apiUrl;
return await http.post(fullUrl,
body: jsonEncode(data), headers: _setHeaders());
}
getData(apiUrl) async {
var fullUrl = _url + apiUrl;
await _getToken();
return await http.get(fullUrl, headers: _setHeaders());
}
_setHeaders() => {
'Content-type': 'application/json',
'Accept': 'application/json',
'Authorization': 'Bearer $token',
'connection': 'keep-alive',
};
}
Laravel method API function which is working.
public function subscribed(Request $request) {
$subscription = new Subscription;
$subscription->title = $request->name;
$subscription->amount = $request->amount;
// $subscription->payment_id = $request->order_id;
// $subscription->razorpay_id = $request->razorpay_id;
$subscription->payment_done = 1;
$subscription->category_id = $request->category_id;
$subscription->user_id = $request->user_id;
$subscription->save();
return response()->json($subscription);
Postman response working. Postman API Response
It was my mistake, actually I was not doing things properly, I created new method first postData in network class.
postData(data, apiUrl) async {
var fullUrl = _url + apiUrl;
await _getToken();
return await http.post(fullUrl, body:jsonEncode(data), headers: _setHeaders());
}
Then I updated my Razorpay's Success Event handler method.
void _handlePaymentSuccess(PaymentSuccessResponse response) async {
// orderId = 12123;
// razorpayId = response.paymentId;
var data = {
'name': name,
'amount': amount,
// 'order_id': orderId,
// 'razorpay_id': razorpayId,
'category_id': categoryId,
'user_id': userId};
var res = await Network().postData(data, '/subscription');
var body = json.decode(res.body);
if (body['success']) {
Fluttertoast.showToast(
msg: "SUCCESS: " + response.paymentId, timeInSecForIosWeb: 4);
} else {
Fluttertoast.showToast(
msg: "Kindly Contact US: " + response.paymentId, timeInSecForIosWeb: 4);
}
// _subscription();
}
