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

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

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

@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.

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 👍

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!

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

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

Yes, the specific steps I laid out seem to reproduce it consistently when using Dart 3.6.0. It does not reproduce with Dart 3.5.x, because pub selects an older version of dartdoc. Once sass/dart-sass#2469 lands you'll probably need to check out an older version of the repo to force it to use Dartdoc 8.3.1.

I can confirm that the issue only happens on Dart 3.6, we saw this error when running pana in Formz's CI and bumping the CI down to an older Flutter (and Dart) version mitigated it for us.
