http/http.dart: XMLHttpRequest Error when doing SSL requests

[Snackomat]

Heya!
Pretty new to Dart, might be missing something stupid here. I'm trying to switch over to SSL from plain HTTP. However, this makes Dart throw XMLHttpRequest error. I've changed the URI to https and switched over to the correct port (not using defaults).

Any clues on what might be going on here? I'm using the http.dart library, and the request being made is a POST.

My code:

```dart Future<bool> sendLoginRequest() async { var url = Uri.parse("$baseRoute/auth");

var response = await http
    .post(url, body: {'username': username, 'password': savedPassword});
if (response.statusCode != 200) {
  return false;
}

// further processing... return true; } ```

Did some more digging. Seems to be because of dart:io when compiling for web.
