Version used: 1.0.0-alpha01

Devices/Android versions reproduced on: Pixel 4a (Android 11)

We set our app theme programmatically based on user preference, loaded from shared preferences at startup. Pre-Android 12 we called context.setTheme() before setContentView(), but with the Splash Screen library we lose control over this since SplashScreen.setPostSplashScreenTheme() reads the postSplashScreenTheme attribute directly from the theme. We can add a dark mode implementation in values-night but still it only follows the system dark mode and cannot respect an app-level user preference to force a dark theme.

It would be nice to have a callback like setOnExitAnimationListener or a mutable property on SplashScreen to allow setting the postSplashScreenTheme programmatically.
