I am getting a XMLHttpRequest error in Flutter Web for Razorpay API call using http post from past 4 days I searched on whole internet but no solution worked in my case.
Below is my Post request code using http: ^0.13.4 package:
Future<String> postRequest(String amount) async {
var url = Uri.parse('https://api.razorpay.com/v1/orders');
var key = 'rzp_test_Xx7Zw7hLfzozf6';
var secret = '7PgbvLaODVzRbb9oRcaqCZMi';
var auth = 'Basic ' + base64Encode(utf8.encode('$key:$secret'));
print(auth);
var body = json
.encode({"amount": 50000, "currency": "INR", "receipt": "rcptid_11"});
var id = DateTime.now().millisecondsSinceEpoch.remainder(100000).toString();
var client = http.Client();
var response = await client.post(
url,
headers: {
'Content-Type': 'application/json',
'Authorization': auth,
},
body: body,
);
print(json.decode(response.body));
return json.decode(response.body);
}
The Curl command:
curl -X POST https://api.razorpay.com/v1/orders-u <YOUR_KEY_ID>:<YOUR_SECRET>-H 'content-type:application/json'-d '{ "amount": 50000, "currency": "INR", "receipt": "rcptid_11"}'
The complete error:
Error: XMLHttpRequest error.

I have tried every solution over Internet but nothing worked.
This smells of a CORS error, so I just pasted your code into Dartpad, opened the Chrome console and hit run. As expected, it was a CORS error.
Next step was then to search api razorpay cors, which threw up a bunch of results all complaining about the same error (all with no solution - which doesn't bode well - typically means there isn't a solution).
Next step was to notice that no decent payment API would have you include credentials into a client side app, especially a browser app. A simple inspection of the headers in the Chrome console reveals your username/password credentials. The implication of this is that you're using the API incorrectly.
This is quickly confirmed by looking at the Razorpay website which confirms that the order api is a Server-Server api. Another clue is that all the sample code for this api is in languages like PHP, Java, Node.js, etc - i.e. for the back end.
Answer: you must not call this API from the Flutter app. It must be called from your back end.
