SafeArea class Null safety

A widget that insets its child by sufficient padding to avoid intrusions by the operating system.

For example, this will indent the child by enough to avoid the status bar at the top of the screen.

It will also indent the child 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.
