Switch to SplashScreenAPI for Android

[aykutuludag]

Hello! I'm using this plugin for a long time. Google Play gives the following alert:

Double splash screen
Warning
The crawler detected a blank loading screen or a custom splash screen that is shown in your app after the system splash screen. Users launching your app on Android 12 or higher will see 2 splash screens.

To fix this issue, update your app to use the SplashScreen API.

Probably other devs getting same warning too.
