CupertinoButtonModifier class
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.
{@tool dartpad} This sample shows produces an enabled and disabled CupertinoButton and CupertinoButton.filled.
** See code in examples/api/lib/cupertino/button/cupertino_button.0.dart ** {@end-tool}
