Do I need a Firebase project to use Firebase App Check?

I want to secure my own custom API for my Flutter app. I came across Firebase App Check, but I do not want to use Firebase.

Can I use Firebase App Check without a Firebase project? It seems to like there is not Firebase involved. Only other app attestation services. https://firebase.google.com/docs/app-check/flutter/custom-resource

  • Do I need a Firebase project to use Firebase App Check?

    Yes.

    It seems to like there is not Firebase involved. Only other app attestation services.

    Firebase is not an attestation provider but it uses others providers and it's a bit easier to integrate those providers using Firebase SDK than directly using them. e.g reCAPTCHA v3 for web apps.

    Once you integrate the Firebase App Check SDK in your Flutter app, you'll have to get the App Check token using getToken() and add it in your API request. Then you just need to verify the token in your backend using the Firebase Admin SDK.
