setSystemUiVisibility and View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR DEPRECATED no Example found in Stack or Google [duplicate]

Question

I have updated the project target API version to 30, and now I see that the systemUiVisibility property is deprecated.

The following kotlin code is the one I'm using which is actually equivalent to setSystemUiVisibility method in Java.

playerView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LOW_PROFILE
            or View.SYSTEM_UI_FLAG_FULLSCREEN
            or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION)

Please let me know if you have got any stable replacement for this deprecated code. The google's recommendation is to use WindowInsetsController, but I don't how to do that.

For compatibility, use WindowCompat and WindowInsetsControllerCompat. You'll need to upgrade your gradle dependency for androidx.core to at least 1.6.0-alpha03 so that there will be support for setSystemBarsBehavior on SDK < 30.

private fun hideSystemUI() {
    WindowCompat.setDecorFitsSystemWindows(window, false)
    WindowInsetsControllerCompat(window, mainContainer).let { controller ->
        controller.hide(WindowInsetsCompat.Type.systemBars())
        controller.systemBarsBehavior = WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
    }
}

private fun showSystemUI() {
    WindowCompat.setDecorFitsSystemWindows(window, true)
    WindowInsetsControllerCompat(window, mainContainer).show(WindowInsetsCompat.Type.systemBars())
}

For devices with notches at the top of the display, you can add the following to your v27 theme.xml file make the UI appear either side of the notch:

<item name="android:windowLayoutInDisplayCutoutMode">shortEdges</item>
