[firebase_app_check] Which plugins correspond to "Firebase release 9.20.0" ?

[MarcVanDaele90]

Some of our customers report appcheck errors when they restart in the morning.
I'm quite sure I'm running into the same issue as reported here for JS: firebase/firebase-js-sdk#6708

The issue states it is fixed in Release 9.20.0

Is the same fix also available in the Flutter firebase plugins?
Can I find out in which plugin and in which version?
