http request XMLHttpRequest error on dart / flutter

Question

I'm trying to get some data from this API, I got the XMLHttpRequest error even when I use this solution:

import 'package:http/http.dart' as http;

void main() async {
  
  var _headers = {
    "Access-Control-Allow-Origin": "*",
    'X-API-KEY': 'SqD712P3E82xnwOAEOkGd5JZH8s9wRR24TqNFzjk'
  };
  var url = "https://api.sunnah.com/v1/collections/muslim";

  var res = await http.get(Uri.parse(url), headers:_headers);
  print(res.body);
}

Cannot reproduce Your issue, it works as expected, see screenshot: pasteboard.co/WNDnnbgYESJf.jpg — num8er

It'll be working fine in production mode, but you can fix it in development mode as well, I have answered this one in an another stackoverflow post.

In my case, simply resolved by adding http://localhost:port (sender) to CORS_ALLOWED_ORIGINS in settings file.
