Couldn't connect to flutter web

[Puspharaj]

flutter run -d web-server --web-port 5000

I can see my app up and running at http://localhost:5000/#/.

But i cannot connect Dart dev tools, it says connect to running app. If i provide the url, exception throws "cannot connect".

PS: dont ask for sample code you can mimic the issue with sample application.

@elliette is this expected to work outside of google3?

I hope so! Trying to enable using Github codespaces for Flutter development and this is a key requirement to unlock that

Dart DevTools isn't supported for the web-server device, only the chrome device. Is there a reason why you are using web-server instead of chrome?

The web-sever device does support debugging from VS Code though, so if you launch your app with the web-server device option from VS Code you can debug from there.

Hmm just to double check a couple of assumptions here as it sounds like I may potentially be on the wrong track here.

• Github codespaces is a managed dev environment (comparable to the new idx.dev project) that allows me the ability to specify my dev environment as a Dockerfile (example of one I am using here: https://github.com/dropbear-software/crm/blob/main/.devcontainer/Dockerfile)
• That environment is then exposed to me via a HTTP interface

Therefore unless I am missing something important here I can't(?) really tell it to use Chrome as it's running inside of a docker container and it wouldn't make sense to include one in there either because how would it launch?

Going back to that idx.dev reference it looks like they have already solved that specific problem that I am encountering here, just not sure how but I am very keen to get an invite and start using it ;)

Are you experiencing this issue or having you found a workaround? If not feel free to re-open so we can investigate. Thanks!
