Flutter HTTPS Handshake error in client (OS Error: CERTIFICATE_VERIFY_FAILED: ok(handshake.cc:363))

Question

A colleague has given me a Flutter project to try to build the app in iOS (I use a Mac, we both use Android Studio). Everything is ok except for this error:

Handshake error in client (OS Error: CERTIFICATE_VERIFY_FAILED: ok(handshake.cc:363))

If I use HTTP instead of HTTPS it works obviously. My colleague said he solved by adding this line of code:

client.badCertificateCallback = (X509Certificate cert, String host, int port) => true;

This line of code is also in my project because the source is the same. So why does it work on Android, but not on iOS?

Answer 1

Old question but my solution was to ensure the time/date set correctly on client

Answer 2

best way for ssl certification problem on all http requests

it is work on both platform (android & ios)

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

void main(){
    HttpOverrides.global = new MyHttpOverrides();
    runApp(new MyApp());
}
