How to build admin-portal web app on window

Thanks for your response, now I can run the web application.

I want to test building an admin-portal web app after making some changes in the language files and then replacing the flutter web app files in invoiceninja.
I’m following this topic:

Rebuilding admin-portal with language changes

However, I am facing a problem because after building the admin-portal web application i am not able to determine which file in the build/web folder should be used to replace public/main.foss.dart.js in invoiceninja.

Can you suggest me which file i need to use?
