HandshakeException: CERTIFICATE_VERIFY_FAILED: self signed certificate error

Question

I trying to get the user's current location in my mobile app. so that, I am calling the getcitydetail api call....and i am getting this error "HandshakeException: CERTIFICATE_VERIFY_FAILED: self signed certificate error"

I tried to by-pass this error by temporarily bypass SSL verification by modifying the HTTP client to accept self-signed certificates, but getting this error.

Answer 1

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

execute this before API called:

DeviceInfoPlugin deviceInfo = DeviceInfoPlugin();
AndroidDeviceInfo androidInfo = await deviceInfo.androidInfo;
// for os 7 override http badCertificateCallback
if((androidInfo.version.sdkInt ?? 30) < 26) {
  HttpOverrides.global = new AppHttpOverrides();
}

using 'device_info_plus' package for getting os api level
