You can also toggle between light and dark mode inside the Google App settings. The new theme option is rolling out today and will gradually expand to more users in the coming week. Some Android 9 users are also reporting that the Dark Mode option is available on their devices.Starting today & fully rolling out this week, dark mode is now available for the Google App on Android 10 and iOS 12/13.
