[version-10.0.0] FirebaseUI Auth - Enter/Exit transition configuration and some queries

[khanshoaib3]

Right now the transition between the different screens are the default one for NavHost i.e., fadein/out, so, is it the scope to add enterTransition/exitTransition to AuthUIConfiguration?

The auth flow seems much better than v9 now and I'm really glad that this is just another composable as I was able to wrap it inside a scaffold to have my own TopAppBar.

Also, I tried adding my own theme, wanted to change the shape of signin/up buttons but the shapes weren't applying.
This is what I was trying:

val localContext = LocalContext.current
    val customTheme = AuthUITheme(
        shapes = Shapes(
            ShapeDefaults.Medium,
            ShapeDefaults.Medium
        ),
        ...
    )
    val configuration = authUIConfiguration {
        theme = customTheme
        providers {
            provider(
                AuthProvider.Google(
                    scopes = listOf("https://www.googleapis.com/auth/drive.file"),
                    serverClientId = "<redacted>"
                )
            )
            provider(AuthProvider.Facebook())
        }
        context = localContext
    }

    AuthUITheme(configuration.theme) {
        FirebaseAuthScreen(
            configuration = configuration,
            onSignInSuccess = {},
            onSignInFailure = {},
            onSignInCancelled = {},
            modifier = modifier,
        )
    }

The shapes were being applied to the input field but not on the buttons. Additionally, I also tried providing customProviderStyles as per the docs but that didn't work either.

I understand that this isn't even out in beta yet so I'm just asking in case these are unintentional bugs.

I also noticed a potential bug, in the email auth screen, the signup screen's top app bar doesn't have a navigate back button.
