Is your feature request related to a problem you're having? Please describe.
When signing in with google when in dark mode, the sheet flashes white first and is a bit abrasive.

Describe the solution you'd like
I'd love for it to support the theme (if it doesn't already, I could be missing something.

Describe alternatives you've considered
I believe I ran into this in another app I built with SwiftUI and I was able to create a custom sheet. I'm not sure if that's possible here.

Hey, thanks for bringing this to our attention! I agree this does seem a bit abrasive. I believe this is something we can't control on my end, but I can forward this issue to a team who might be able to help.
