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 https://github.com/flutter/flutter-intellij/issues/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).

Using Plugin Version: 24.0.1

[devoncarew]

The latest is 24.1.x -

[kunli0]

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

[jacob314]

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.

This is the only thing that looks of interests

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.

[kunli0]

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

[kunli0]

I thought it may have been the machine that I was on which was at work. Now at home following the same process, getting the same results on the Flutter Inspector from the default "New Flutter Project"

[jacob314]

I'm able to repro on windows. This was an issue with how we are handling file paths. Sending out a fix.

[jacob314]

The fix has landed and I'll add a comment to this bug when we publish a new version of the plugin with the fix.

[jacob314]

The fix is available in the just released M24.2 build. Please let me know if the issue is now fixed for you.

[kunli0]

Working as intended. Thanks!

Still not working for me after 24.2 with AS 3.1 and Idea 2018.1.4 (CE)

@cfkloss can you provide some more details of what you are seeing?

1. What is the full path to your flutter application? e.g. "c:/foo/bar/my_flutter_app"
2. Can you include a screenshot showing what the inspector window looks like?
3. Did any internal IDE errors occur? You can check by clicking on the icon in the bottom right corner of the IDE:
4. Does the "Render Tree" tab in the inspector work for you or is it broken as well?

[cfkloss]

@jacob314 I've found the problem.

My projects are all inside a symbolic link folder. The original location is at "d:\Insync\Projects" and the symbolic link is at "c:\Projects\". If I open it at the original location it works as intended but it does not work when it is opened from the symbolic link folder.

1. The full path to the application is "c:\Projects\Testes\teste\"
2. screenshot included
3. No internal IDE error
4. Yes, the render tree works.

Now that i found the problem I can work around it by opening the original location. But it would be great if it could work from inside a symbolic link folder also.

[nicodeslandes]

Having the same problem with the latest version. Exactly the same setup as @cfkloss , my "C:\Projects" is a symbolic link. Opening the original location fixes the problem, but I'd rather not have to do that.

[devoncarew]

cc @jacob314 as it looks like symbolic links can confuse the inspector

[Hesamedin]

The issue is still happening. I am using the latest version of the Android Studio, Dart, and Fluter SDKs. What I can say is that I usually don't close my IDE at night (when I don't work). Then the next day, I continue my work. In this particular case, I closed the IDE, restarted it, and then launched my emulator. I was able to see the tree in the Flutter Inspector tab.
