Can no longer build drift: Could not resolve annotation for [various]

[stx]

We can no longer compile via build_runner on Flutter 3.7.3, drift 2.5.0 and drift_dev 2.5.2.

flutter cleans, dependency upgrades and various Flutter and dependency downgrades don't appear to have any effect.

We have no idea what the issue is or how to go about fixing it. Can you help?

Is there supposed to be a hidden ios/.symlink folder in lib/? Are you doing that to vendor other packages into your repository or is that something that Flutter does?

You could probably work around this issue by adding this to your build.yaml:

targets:
  $default:
    sources:
       exclude:
         - "lib/ios/.symlinks/**"
    builders:
      drift_dev:
        options:
          mutable_classes: true

This error probably comes from the fact that other packages are using annotations not in your local package graph used by build_runner because their sources were blindly copied into lib/. Still, it would be interesting to know where that comes from.

@simolus3 Interesting. It looks like this is a side effect of running certain Flutter commands while in the ios folder. Just deleting that folder just fixed it. Thanks a ton!
