Well, making https request with apps developed with other programming languages (on sandbox) work fine, tcp/udp socket connections(with dart) work fine, other apps with network part work fine, browsers work fine. But flutter app in release mode can not make https requests (on sandbox).
Windows is not macOS, it has totally different sandbox
The triaged-desktop

label or fyi-desktop
label.
I've made a flutter desktop app, build it in a Release mode and decided to test in on Windows' SandBox. The problem is that any https request to any server leads to "Handshake error in client (OS Error: CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate(handshake.cc:363))" error. If this happens on an official SandBox, it also might happen on default Windows version of some user. In this example i'm making request to Google Analytics server and encounter this error.
minimal code sample
```dart import 'dart:io'; import 'package:flutter/material.dart'; void main() => runApp(MyApp()); class MyApp extends StatefulWidget { @override _MyAppState createState() => _MyAppState(); } class _MyAppState extends Statepreview
