Implementation

The implementation for the One Tap Sign In, using this component, is extremely simple. Simply store val oneTapState = rememberOneTapSignIn(...) and open the menu when the user needs to sign in.

@Composable
fun LoginPage() {
    val oneTapState = rememberOneTapSignIn("YOUR_CLIENT_ID") { credential ->
        Log.d("OneTapSignIn", "Success!")
        // TODO: Authenticate using something like Firebase
    }
  
    Button(onClick = { oneTapState.openMenu() } { Text("Sign In With Google") }
}

Works With Emulator

Many developers encounter issues with the One Tap Sign-In functionality when using an emulator. The common solution is to use a real device. In order to get around this, there is now an opt-in to use the old Google Sign-In method. Developers can request additional scopes, gut "requestIdToken" is required in order to authenticate with another back-end like Firebase.
