Answer 1 · 2024-12-18T18:23:21.000Z

Thanks for the detailed report!

Answer 2 · 2024-12-18T18:23:53.000Z

Can you say what version of Dart you are using?

Answer 3 · 2024-12-18T18:45:50.000Z

Can you say what version of Dart you are using?

No problem!

dart --version

Answer 4 · 2024-12-19T16:12:56.000Z

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

Answer 5 · 2024-12-19T16:21:42.000Z

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

Answer 6 · 2024-12-19T16:36:40.000Z

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.

Answer 7 · 2024-12-19T17:48:28.000Z

@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.

Answer 8 · 2024-12-19T18:07:35.000Z

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.

Answer 9 · 2024-12-19T18:12:02.000Z

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

Answer 10 · 2024-12-19T18:58:43.000Z

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!

Answer 11 · 2024-12-19T20:42:03.000Z

@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.

Answer 13 · 2024-12-20T14:46:14.000Z

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.

Answer 14 · 2024-12-26T16:37:55.000Z

Thank you so much for testing! I just pushed another change to that branch. Can you re-global activate (same branch) and re-run? There should no longer be a call to PackageGraph.objectClass at this stack trace line (Mixin.superclassConstraints.<anonymous closure> (package:dartdoc/src/model/mixin.dart:22:54)) so that stack trace line should no longer appear, if there still is a crash.

Answer 15 · 2024-12-29T18:18:59.000Z

Yep, it works for me with that latest change on @srawlins' fork 👍

Answer 16 · 2025-01-01T21:08:04.000Z

Worked for me as well! Sorry for the delayed response and thanks for the fix! 💙

Answer 17 · 2025-01-02T15:49:30.000Z

Shwew, glad to hear the fix works!

Answer 18 · 2025-01-13T04:18:04.000Z

@srawlins FYI it looks like this fix hasn't been deployed yet and it's affecting the latest versions of hydrated_bloc and replay_bloc on pub.dev (cc @isoos)

See felangel/bloc#4331

Answer 19 · 2025-01-13T16:26:22.000Z

Please follow dart-lang/pub-dev#8456.
