Dart DevTools needs to be activated with 'pub global activate devtools'

[mustaqimM]

Describe the bug
Hi there, I launched an app with lsp-dart-run and then attempted to open DevTools with lsp-dart-open-devtools.

I can't seem to run lsp-dart-open-devtools; when running lsp-dart-run, it doesn't expose the local URL to access it. (eg. http://127.0.0.1:42277/7ExjleCaLVU=/). Am I doing something wrong?

According to this issue flutter/devtools/issues/6550: flutter pub global activate devtools is deprecated; which is how lsp-dart-devtools--start attempts to start DevTools. And it should be run as dart devtools instead.

Running flutter run directly exposes DevTools and the URL. I don't know how it's meant to be when an editor runs it since lsp-dart-run doesn't show it, nor does dap-debug.

Note
Before logging the bug please make sure that the issue is reproducible with latest melpa packages.

To Reproduce

1. Run lsp-dart-run (or dap-debug)
2. lsp-dart-open-devtools

Expected behavior
lsp-dart-run should expose the VM Service URL. And lsp-dart-open-devtools should open DevTools and connect to the running app.
