How to Communicate with a Server Using a Self-Signed Certificate (My Own CA) Without Errors in Flutter's HTTP Client

Write this somewhere

class DevHttpOverrides extends HttpOverrides {
  @override
  HttpClient createHttpClient(SecurityContext context) {
    return super.createHttpClient(context)
      ..badCertificateCallback = (X509Certificate cert, String host, int port) => true;
  }
}

HttpOverrides.global = new DevHttpOverrides();
