CupertinoButton class Null safety

An iOS-style button.

Takes in a text or an icon that fades out and in on touch. May optionally have a background.

The padding defaults to 16.0 pixels. When using a CupertinoButton within a fixed height parent, like a CupertinoNavigationBar, a smaller, or even EdgeInsets.zero, should be used to prevent clipping larger child widgets.
