I try to create a cloudflare tunnel to connect to a flutter website running (using "flutter run" command) on my local MAC. I have done this successfully for connecting to a web service running locally. But the tunnel for the flutter website does not work. https://developers.cloudflare.com/cloudflare-one/connections/connect-networks/ says "Cloudflare Tunnel can connect HTTP web servers, SSH servers, remote desktops, and other protocols safely to Cloudflare.". Does it mean tunnel does not work for flutter websites running via "flutter run"? Thanks very much for any clue.
