Hi @Piinks, I hope you're doing well.
I re-created my last PR, you can find the last one here #70585
in this PR, I updated the copyWith function of the OutlinedBorder subclasses, and added some test for each of them.

This LGTM! Thank you for returning and finishing this contribution! 🎉

Can you update your branch with the latest from master? I think that should resolve the failing check here due to an infra issue.
