Source is not displayed in Timeline when profiling app

[sceee]

I am executing a flutter app in profile mode using the following VS Code config:^

{
            "name": "Profile App",
            "program": "lib/main.dart",
            "request": "launch",
            "type": "dart",
            "flutterMode": "profile"
}

Then, when having a look at the Timeline in Dart DevTools, I unfortunately do not see the source:

It's empty for the complete stack and it's empty in the browser as well as in the embedded VS Code view.

I'm actually not sure if the app is executed correctly in profile mode as it seems I cannot see any of my own code in the stack. But this could also be because I am not yet very experienced in using the profiler in DevTools. I just execute the app using the above mentioned profile launch config and then open the DevTools/Timeline, make some action in the app and then click refresh.

Versions are the following:

• Device info from DevTools:

We don't currently have file URIs in profile mode - this is due to dart-lang/sdk#37553. I will ping that issue.

Closing this issue - the source column has been removed from the CPU profiler for flutter apps (see #2471). It can be added back once dart-lang/sdk#37553 is fixed.
