The official Flutter documentation can be found here.

Error in Network Resources section of flutter doctor

Got the following result when I ran flutter doctor.
Network resources
X A cryptographic error occurred while checking "https://pub.dev/": Handshake error in client
You may be experiencing a man-in-the-middle attack, your network may be compromised, or you may have malware installed on your computer.
X A cryptographic error occurred while checking "https://storage.googleapis.com/": Handshake error in client You may be experiencing a man-in-the-middle attack, your network may be compromised, or you may have malware
installed on your computer.
X A cryptographic error occurred while checking "https://maven.google.com/": Handshake error in client You may be experiencing a man-in-the-middle attack, your network may be compromised, or you may have malware installed on your computer.

When I tried to run flutter doctor (as I was getting some errors loading network image in an app) I ran into some issues in network resources part .

    This is the only valid thing I found.

    Quoting from the link above:

    first i deleted flutter folder and unzip the below download link to C:/Dev/flutter
    https://storage.googleapis.com/flutter_infra/releases/beta/windows/flutter_windows_v0.8.2-beta.zip
    and in environment variables in path i Added new path C:/Dev/flutter/bin
    and run flutter doctor in git command so it’s working now

    I would try also a complete scan for malwares in your computer.

    Check the link, scan your computer and let me know if this solved your problem.

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

    Future<void> main() async {
  HttpOverrides.global = MyHttpOverrides();

}

    add this in main.dart
