Publish simple application to another web server

Create simple static website and publish to web - https://web-test-4c9rvd.flutterflow.app/

Grab the FlutterFlow CLI to import project and build it

Tested the web app but get an empty page.

Resolve the pinned version issue and still see the blank web page

Ran into dependency issues. Did not resolve.

Tried changing the index.html to reference the current directory

......

Wrote this post to seek help. Anyone see what I'm doing incorrectly? Thanks a tons for any thoughts, ideas, and solutions.

FYI -

here is my flutter doctor

Also, tested by opening the html directly and also opening from nginx webserver.
