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}
