SafeArea constructor Null safety
Creates a widget that avoids operating system interfaces.
The left, top, right, bottom, and minimum arguments must not be null.
Implementation
const SafeArea({
super.key,
this.left = true,
this.top = true,
this.right = true,
this.bottom = true,
this.minimum = EdgeInsets.zero,
this.maintainBottomViewPadding = false,
required this.child,
}) : assert(left != null),
assert(top != null),
assert(right != null),
assert(bottom != null);
