[srawlins]

Thanks for the detailed report!

[srawlins]

Can you say what version of Dart you are using?

[felangel]

Can you say what version of Dart you are using?

No problem!

dart --version
Dart SDK version: 3.6.0 (stable) (Thu Dec 5 07:46:24 2024 -0800) on "macos_arm64"

[srawlins]

Is this consistently reproducible? I can't reproduce using the steps above.

[srawlins]

@nex3 can you say if your repro is consistent? I've tried a few times in a row with sass_api and cannot reproduce.

[felangel]

Is this consistently reproducible? I can't reproduce using the steps above.

I’m able to consistently reproduce this and it was reproducible in my CI as well.

[felangel]

@srawlins let me know if there's anything else I can do to help. Happy to debug it further on my local machine later today.

[srawlins]

I have some ideas of how to fix, but I'd love to be able to reproduce locally. I can push some potential fixes to a branch, and if you could global activate dartdoc via -sgit and --git-ref, that would validate the fix.

Sounds great! Happy to verify the fix -- let me know when you have a branch 👍

[srawlins]

Thanks much @felangel! The branch is here: https://github.com/srawlins/dartdoc/tree/pre-compute-object

So I think you can activate dartdoc with: dart pub global activate -sgit https://github.com/srawlins/dartdoc.git --git-ref pre-compute-object

🤞 Hope that command works, and hope the fix works!

[felangel]

@srawlins looks like it's still not fixed on my end unfortunately :(
