Flutter Web How to publish and host a site to other than a root folder

Currently i was testing flutter web with default app template i created a new project and build web target with

`flutter build web`

put all the files in subdirectory of local server, thus i can access them from

say http://127.0.0.1:43110/1ETE7PzFgfVdJ9YBhoG2uq1g5jwZ6N9Dou/

but i was not able to load the flutter app correctly.

i was getting the below errors

Access to XMLHttpRequest at 'http://127.0.0.1:43110/assets/FontManifest.json' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
