Extend body to the bottom edge of the screen in android devices with full screen indicator - removing the black color below the indicator

I think it is because of edge-to-edge issue but not sure. That's why unable to figure out a solution from Flutter side. Need suggestion on how to extend scaffold body up to bottom edge below the indicator or at least change the black color to white.
Tried some packages from pub but didn't work.
Key point: don't give the navigation bar an opaque color and don't apply bottom inset padding to the entire root. The background should draw behind the gesture indicator, while interactive content can use the bottom inset for safe spacing.
