CERTIFICATE_VERIFY_FAILED about signalr_client HOT 3 OPEN

I'm having the same issue when connecting from either emulator or phone.

E/flutter (26762): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: HandshakeException: Handshake error in client (OS Error:
E/flutter (26762): CERTIFICATE_VERIFY_FAILED: unable to get local issuer certificate(handshake.cc:354))

@R3ckaH hi, download and add this line in dartio_http_client.dart line 38

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

I am having the same issue when using the iOS emulator. It seems to be happening when I am using my localhost signalr hub. For example, when i publish the code out to azure I do not get this error but when I try to connect to my signalr hub at https://localhost:8080/hub?id={ID} i will receive this error.

@R3ckaH I tried adding your code above and it did not solve the problem for me.
