Describe the bug

The "fullscreen" switch doesn't work for Android <12v in System.dark mode.
If I manually add to "android/app/src/main/res/values-night/styles.xml" next items, then all is OK

        <item name="android:windowFullscreen">true</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>

Configuration

dependencies:
  flutter:
    sdk: flutter
  flutter_native_splash: ^2.3.0

flutter_native_splash:
  image: assets/images/loglo3_2x2.png
  background_image: assets/images/bg01-1.png
  fullscreen: true
  android_12:
    image: assets/images/loglo3_2x2.png
    color: "#122031"

Device (please complete the following information):

• Device: [Pixel 2], but I think, what it will reprodice on any AVD Emulator, with OS < Android-12
• OS: [API 29]

To Reproduce
Steps to reproduce the behavior, using the example app:

1. Set the config on the example app to 'flutter_native_splash/fullscreen'
2. Run in an emulator configured with 'Settings >Display >Dark theme ON'
3. See what top system icons stay on splash screen when System display in dark mode
