CupertinoDialogAction.isDefaultAction is a misleading name for iOS developers.

On iOS UIAlertAction.Style is an enum with 3 cases:

case `default`
case cancel
case destructive

CupertinoDialogAction's constructor's signature:

const CupertinoDialogAction({
  VoidCallback onPressed,
  bool isDefaultAction: false,
  bool isDestructiveAction: false,
  TextStyle textStyle,
  @required Widget child
})

where isDefaultAction is easily mistakable for the default case but they do different things and are not mutually exclusive.

Should probably explicitly state in the documentation that isDefaultAction is not the same as UIAlertAction.Style.default
