Thank you for the report! It seems we are not registering correctly the debug flags for web development, I can take a look on this soon.

Hey @ps-143, I just tested with my flutter_sample and it worked properly 😕.

It connects to chrome correctly.

Could you try adding this config to your emacs and testing again?

(setenv "CHROME_EXECUTABLE" "/path/to/your/chrome")

[sudo-human]

I tried setting "CHROME_EXECUTABLE" to "/opt/google/google-chrome/chrome" but still it didn't work. Using flutter-run works and dap-debug works when using an android device. I still can't figure out the problem. I'm used snap to install the flutter and dart sdk.

I have also tried downgrading emacs to 27

[ericdallo]

Hum, could you try to rm ~/.emacs.d/.extension/vscode, update both lsp-dart and dap-mode to latest, run dap-dart-setup again and try again?

[sudo-human]

I tried your solution but it's still not working for me.

[sudo-human]

It's working absolutely fine on android devices but just not for web.

[ericdallo]

I see, could you try on my flutter_sample from above?

[sudo-human]

I'm using doom-emacs and I've tried flutter run and it runs fine using that, I think that dap-debug is better as it provides hot-reload as well. I tried a new project in flutter with the boiler plate code but its still the same

[ericdallo]

Really odd, dap-debug just trigger the launch using the debug.js inside the extension, which will run flutter run --machine under the hood, not sure what options left for us here :/

[sudo-human]

I'm using the flutter run command from flutter.el package

[sudo-human]

Earlier when I had to work on flutter I used emacs and this worked perfectly fine for me.

[ericdallo]

Maybe some dap-mode issue @yyoncho ?

Is there anything relevant on dap-output or dap-stderr buffers?

It's odd that works on my side...

[sudo-human]

Any help from this?

[ericdallo]

Nothing useful there, I don't think we have any other log besides that buffer unfortunatelly

[ericdallo]

@ps-143 could you try the same steps from https://github.com/emacs-lsp/lsp-dart/issues/102 ?

Mine's not a flutter one, Dart using web template instead. And dap-debug gives me this:

web/main.dart:1:8: Error: Dart library 'dart:html' is not available on this platform.
import 'dart:html';

From command-line, webdev serve however is fine. was just looking for a way to do it from within emacs.
