Flutter の httpクライアントで、簡易的にオレオレ証明書(自己署名証明書)のサーバとエラーなく通信するには

どこかにこれ書く

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();
