useSafeAreaInsets returns all insets value 0 on devices with notch using immersive mode

[mauryaak15]

Aim

I want my app to be full screen, no statusbar, no navigation bar, in case of single and double cutout (notches), I want to give padding having suitable background color

Current code in use for full screen immersive mode

private static final int UI_FLAG_IMMERSIVE = View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // hide nav bar
            | View.SYSTEM_UI_FLAG_FULLSCREEN // hide status bar
            | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && Build.VERSION.SDK_INT < 30) {
  hideSystemUI();
  getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)
} else if (Build.VERSION.SDK_INT >= 30) {
  WindowCompat.setDecorFitsSystemWindows(getWindow(), false);
  WindowInsetsControllerCompat controller = WindowCompat.getInsetsController(getWindow(), getWindow().getDecorView());
  if (controller != null) {
      controller.hide(WindowInsetsCompat.Type.statusBars() | WindowInsetsCompat.Type.navigationBars());
      controller.setSystemBarsBehavior(WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);
  }
}

private void hideSystemUI() {
  View decorView = getWindow().getDecorView();
  decorView.setSystemUiVisibility(UI_FLAG_IMMERSIVE);
}

Problem

I want get the inset of cutout area in android and when I am using const insets = useSafeAreaInsets(); it is returning all zero values.

Expected

PixelUtil.toDIPFromPixel(getWindow().getDecorView().getRootView().getDisplay().getCutout().getSafeInsetTop()) this code is returning correct value for all edges
