@incendial the DCM check here seems to be failing with a false positive: https://github.com/flutter/devtools/actions/runs/16272396154/job/45943159382?pr=9310. When I remove this ignore, I get hit with a warning about avoiding dynamic instead.

Do you mean you get a warning locally? If so, then are you on 1.30.0 locally as well?
The rule was updated in 1.30.0 so this warning on CI is correct, this parameter https://github.com/flutter/devtools/blob/master/packages/devtools_app/lib/src/screens/vm_developer/object_inspector/object_store.dart#L48 gets its type implicitly because of the override.

Ah, it seems it is actually dynamic.

I tested it locally with 1.30.0, I don't see a warning when the ignore is removed.
But there are 2 ways to "fix" this without updating the tool:

1. add explicit dynamic type: dynamic data and keep the ignore.
2. add a global ignore for avoid-dynamic: // ignore_for_file: avoid-dynamic
