SliverSafeArea class Null safety
A sliver that insets another sliver by sufficient padding to avoid intrusions by the operating system.
For example, this will indent the sliver by enough to avoid the status bar at the top of the screen.
It will also indent the sliver by the amount necessary to avoid The Notch on the iPhone X, or other similar creative physical features of the display.
When a minimum padding is specified, the greater of the minimum padding or the safe area padding will be applied.

- SafeArea, for insetting widgets to avoid operating system intrusions.
- SliverPadding, for insetting slivers in general.
- MediaQuery, from which the window padding is obtained.
- dart:ui.FlutterView.padding, which reports the padding from the operating system.
