GoogleSignInConfig
constructor(serverClientId: String = GOOGLE_WEB_CLIENT_ID, filterByAuthorizedAccounts: Boolean = true, signUpFallback: Boolean = true, autoSelectEnabled: Boolean = true)(source)
Parameters
filterByAuthorizedAccounts
true shows only accounts that already signed in to this app — the returning-user path, and the one that must be tried first so the bottom sheet stays quiet.
signUpFallback
when the filtered request finds nothing (every brand-new user), retry once with the filter off. Without this, a first-time user gets "no credentials" and the sign-in button looks broken. The cost of the retry is one extra round trip on a cold account only.
autoSelectEnabled
skips the chooser when exactly one account has been used before. Only honoured after the user has signed in once, so it cannot surprise a first-time user.
