SocketException: Connection failed in Docker on CI

[tjarvstrand]

Describe the bug

There seems to be some incompatibility between custom_lint and Flutter when running Linux in Docker, at least in CI (I tried both GH actions and Circle CI, Flutter versions 3.10.6 and 3.13.0). Runs fail with SocketException: Connection failed (OS Error: Cannot assign requested address, errno = 99), address = ::1, port = 42977 (the port number varies)

Example run in GH actions:
https://github.com/tjarvstrand/custom_lints_test/actions/runs/5910988866/job/16033101882

To Reproduce

Here's minimal example repo that reproduces the issue: https://github.com/tjarvstrand/custom_lints_test

Removing Flutter references from pubspec.yaml allows the check workflow to pass.

Expected behavior
The check should pass even with flutter as a dependency.
