How do I implement App Check with Flutter for Android release?

I’ve been trying for a few days to implement App Check using Play Integrity (since SafetyNet, which is all I could get to work before is deprecated) but no matter what I do, I can only get it to work in development using the debug token, and not in release. The official documentation seems to stop after saying how to set it up for development/debug. Whenever I try to sign in on a release version, I get the error: Firebase App Check token is invalid. With an unknown/null key. Has anyone been able to get this to work recently?

I have added SHA-256 to AppCheck of the Google Play Console, and also when generating the .json of google service. In debug mode it works if I add the token it generates to the AppCheck token manager, but as soon as I generate the apk it no longer works.
