🚀 [auth] Allow passing in raw nonce when using signInWithCredential

[henribru]

When using signInWithCredential, there doesn't appear to be a way to pass in the raw nonce, which is required if you're using an id token that contains a nonce: https://firebase.google.com/docs/reference/kotlin/com/google/firebase/auth/OAuthProvider.CredentialBuilder#setIdTokenWithRawNonce(java.lang.String,java.lang.String)

Maybe it could just be added to the AuthCredential interface and then passed down into the native signInWithCredential along with the provider ID, token and secret

Hey @henribru - how do they do it in firebase-js-sdk ? Our "job" - in the sense of discriminating between things we can do here and things we cannot - is to implement the firebase-js-sdk APIs, either directly binding them to identical APIs in firebase-ios-sdk / firebase-android-sdk or doing internal things to "bend" what an firebase-js-sdk-compatible API implementation gives us into whatever shape the native firebase-android-sdk / firebase-ios-sdk make available to us, so that we end up with similar results

So always best to start with the firebase-js-sdk guides and reference docs to see how they would to it as that will have to be our API, then check the native ios/android docs make available to see if it is feasible in the native context

They do it basically how I'm suggesting, I believe. When creating a credential rawNonce is one of the options you can pass in:
https://firebase.google.com/docs/reference/js/auth.oauthprovider.md#oauthprovidercredential
https://firebase.google.com/docs/reference/js/auth.oauthcredentialoptions.md#oauthcredentialoptions_interface
