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.

This sample shows produces an enabled and disabled CupertinoButton and CupertinoButton.filled.

To create a local project with this code sample, run:
flutter create --sample=cupertino.CupertinoButton.1 mysample

alignment → AlignmentGeometry: The alignment of the button's child.
final
borderRadius → BorderRadius?: The radius of the button's corners when it has a background color.
final
child → Widget: The widget below this widget in the tree.
final
color → Color?: The color of the button's background.
final
disabledColor → Color: The color of the button's background when the button is disabled.
final
enabled → bool: Whether the button is enabled or disabled. Buttons are disabled by default. To enable a button, set its onPressed property to a non-null value.

minSize → double?: Minimum size of the button.
final
onPressed → VoidCallback?: The callback that is called when the button is tapped or otherwise activated.
final
padding → EdgeInsetsGeometry?: The amount of space to surround the child inside the bounds of the button.
final
pressedOpacity → double?: The opacity that the button will fade to when it is pressed. The button will have an opacity of 1.0 when it is not pressed.
