Thrown exception is different in iOS and android

[abdallah-odeh]

I have a case that should fire the exception CertificateNotVerifiedException, also the logic is handled under that specific exception type

if (err.error is CertificateNotVerifiedException) {
   fireSSLNotMatchException();
   return super.onError(err, handler);
}

in android, this exception is fired as expected, here is the log:

E/flutter ( 7061): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(CONNECTION_NOT_SECURE, Connection is not secure, Fingerprint doesn't match, null)
E/flutter ( 7061): #0      StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:653:7)
E/flutter ( 7061): #1      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:315:18)
E/flutter ( 7061): <asynchronous suspension>
E/flutter ( 7061): #2      HttpCertificatePinning.check (package:http_certificate_pinning/src/http_certificate_pinning.dart:35:19)
E/flutter ( 7061): <asynchronous suspension>
E/flutter ( 7061): #3      CertificatePinningInterceptor.onRequest (package:http_certificate_pinning/src/dio/certificate_pinning_interceptor.dart:46:28)
E/flutter ( 7061): <asynchronous suspension>
E/flutter ( 7061): 

Note that here, the exceptionCode is CONNECTION_NOT_SECURE, the returned exception object is CertificateNotVerifiedException

while in iOS, the fired exception is different; here is the log:

flutter:
[VERBOSE-2:dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(CONNECTION_INSECURE, null, null, null)
#0      StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:653:7)
#1      MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:315:18)
<asynchronous suspension>
#2      HttpCertificatePinning.check (package:http_certificate_pinning/src/http_certificate_pinning.dart:35:19)
<asynchronous suspension>
#3      CertificatePinningInterceptor.onRequest (package:http_certificate_pinning/src/dio/certificate_pinning_interceptor.dart:46:28)
<asynchronous suspension>

the exceptionCode here is CONNECTION_INSECURE, also the returned exception object is CertificateCouldNotBeVerifiedException

so I believe that these should be unified.

Thanks for this observation, exception unified on release 2.1.1
