Enabling "Enforce User Identity Validation" cause ChatwootClientException in SDK

[Abhishek-Vijay]

Hi,
I have been trying to enforce user identity validation in chatwoot SDK but getting this exception -

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Instance of 'ChatwootClientException'
E/flutter (13424): #0 ChatwootClientAuthServiceImpl.createNewContact (package:chatwoot_client_sdk/data/remote/service/chatwoot_client_auth_service.dart:52:7)
E/flutter (13424):
E/flutter (13424): #1 ChatwootClientApiInterceptor.onRequest. (package:chatwoot_client_sdk/data/remote/service/chatwoot_client_api_interceptor.dart:37:19)
E/flutter (13424):
E/flutter (13424): #2 BasicLock.synchronized (package:synchronized/src/basic_lock.dart:33:16)

E/flutter (13424): #3 ChatwootClientApiInterceptor.onRequest (package:chatwoot_client_sdk/data/remote/service/chatwoot_client_api_interceptor.dart:29:5)
E/flutter (13424):

When I dig deeper in the exception, I realized that this exception is caused when createNewContact function is trying to Create Contact using createContactAPI in chatwoot_client_auth_service.dart file. the Exception is -
DioError [DioErrorType.response]: Http status error [500]

this exception came because createConatctAPI expects "identifier_hash" attribute but SDK pass "identifierHash" attribute instead.
since the ChatwootUser function is written this way -
ChatwootUser(
{this.identifier,
this.identifierHash,
this.name,
this.email,
this.avatarUrl,
this.customAttributes});

and client ContactsAPI expects payload in this format -
{
"identifier": "string",
"identifier_hash": "string",
"email": "string",
"name": "string",
"phone_number": "string",
"avatar_url": "string",
"custom_attributes": { }
}

What should I do in this case.?
I am attaching postman screenshots also to describe the issue clearly
