Answer 1

Temporary you can solve this issue with below recommend

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

enter link description here

But my suggestion is you use valid certificate in server side
