Flutter Inspector Widgets Tab is empty

[kunli0]

Steps to Reproduce

Turn on the "Run application with --track-widget-creation" which I assume will bold items in the inspector and allow double clicking to automatically highlight the code where the widget was created. Upon doing so however, the Widgets tree becomes completely empty, not showing anything.

I believe this is a dup of #2029; can you try updating to the latest plugin version (just released) and see if it address the issue?

[devoncarew]

If no, please re-open (/cc @jacob314).

Just updated Flutter Plugin to 24.1 and restarted Android Studio however widgets inspection still empty with "Run application with --track-widget-creation" enabled.

Can you try manually deleting your build directory and re-running to test whether that works around the issue?

[kunli0]

Manually deleted build directory. Build directory was recreated however, same issue. This is what the Inspector looks like.

[devoncarew]

Hmm, the inspector is connected, just no widget info is showing. Do the render tree or performance tabs show anything? Are there any errors in the Android Studio logs?

[kunli0]

The render tree and performance tabs both work fine.

Is it just for this project or for all projects? I expect what is happening is we are failing to detect that any widgets were created by the local project. If you can provide a repro git repro I can test on that would be extremely helpful.

I just created the default "New Flutter Project" and it is still blank in the inspector. The other project was the same thing, with the code in main.dart replaced with This
