App Check with App Distribution

[riccardocescon]

I have enabled AppCheck on the app i am working on.
If i register the Debug Token everything works perfectly.
If i load the release with flutter run --release command, i am not able to use the app due to App Check because it rejects all requests marking them as 'not valid' on the App Check page on Firebase.
If i publish the app on the play console on the Internal Tester and then download the app from there, then i am able to use it.
Isn't the flutter run --release command compiling and singing the apk before loading to my connected physical device?
And then, how should it connect with App Distribution?
Since it's not the play console store, i just load the apk or app bundle generated with flutter build apk --release and it won't work cause of App Check, so is it possible to use both App Check and App Distribution for internal testing?

Im wondering that if you deploy with FIrebase App Distribution and enable AAB deployments, maybe those uses the key from the play store to do the releases?

Im having the same trouble but I can not test it right now, I dont have enough permissions on the play store.
