Serve a (debug)web app without opening a browser window

[LilMouse]

I read that it is possible to serve the web build result from the flutter app.
I think it used to be done with flutter_rust_bridge_serve and that isn't supported anymore.

The guide now shows
flutter run --web-header=Cross-Origin-Opener-Policy=same-origin --web-header=Cross-Origin-Embedder-Policy=require-corp
and I that immediately opens a browser window.

For my use case I would only like to serve, not run, my flutter app and connect manually with the : in a browser of my choice. This might be from another PC in the network.
I am used to doing that by serving the pages in build/web/ but there is nothing there after building.

Some background info: I run my development in a docker container which does not have a browser installed/available and the browser is installed on my system. That is why I would like to only serve the web app and not run it in my build environment.

Is there a way to do this with the flutter_rust_bridge build system?

Hi, I guess one way is to see how to build and serve a standalone flutter app (w/o rust), since the rust part (e.g. wasm files) are already built in steps before the flutter run step.

I indeed managed to make it work by running flutter build web and then serving the contents of the /build/web/ directory.
I did run into the #2914 issue and had to recompile my app first with the correct --wasm-pack-rustflags.

And build a little python script that serves with the correct headers. (Based on a script found here: https://stackoverflow.com/questions/21956683/enable-access-control-on-simple-http-server).

Happy to see it is solved!
