Bypass Certificate Error Using Http

Question

I'm trying to create a proxy server that access third-party API, but their development end point have certificate error. Is there anyway to bypass ssl error when using http.dart?

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

Uri url = Uri.parse("https://url-with-ssl-error.com/endpoint");
http.get(url).then((response) => print(response.body));

and here's the error returned:

Uncaught Error: SocketIOException: RawSecureSocket error (Unexpected handshake error in client) (OS Error: errno = -8172)
Unhandled exception:

Answer 1

Though this question may be out of date, I should still post a short answer for this, in case of someone in the same trouble. This snippet's from my project:

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

HttpClient client = new HttpClient()..badCertificateCallback = ((X509Certificate cert, String host, int port) => true);
var ioClient = new IOClient(client);
http.Response resp = await ioClient.post(uri, body: utf8.encode(json.encode(body)), headers: headers);
...

The issue was mentioned here and also the fix.
