Good change, thanks @jamesderlin!

PS: Can you please bump the CHANGELOG.md and pubspec.yaml? That way we can publish this PR (even though it doesn't have external-facing changes, maybe a +1 bump is enough?)

[jamesderlin]

Okay, I wasn't sure if it was worth the churn of bumping the package version.

Thanks @jamesderlin, this way this revision can be published to pub without having to think "why is this revision failing" :)

Let's merge this when the CI finishes.
