dart - Enable CORS while an XMLHttpRequest error occurs in flutter web

when I will add data to the database using the function, and on the server I have added Access-Control-Allow-Origin so that it is not blocked by CORS, but still error when I looked in the browser console tools tab console

Access to XMLHttpRequest at 'https://int.goo.id/api/pg/sso.register' from origin 'http://127.0.0.1:8080' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

how to deactivate CORS??

For enabling cors on my server and to resolve XMLHttpRequest error in flutter web

I am using this in my .htaccess file for allowing access to certain domains only

 <ifModule mod_headers.c>
    SetEnvIf Origin "http(s)?://(localhost:25120|domain.com|domain2.com)$" AccessControlAllowOrigin=$0
    Header add Access-Control-Allow-Origin %{AccessControlAllowOrigin}e env=AccessControlAllowOrigin
    Header always set Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"
 </ifModule>
