Constructors
- CupertinoActivityIndicator({Key? key, Color? color, bool animating = true, double radius = _kDefaultIndicatorRadius})
- 
          Creates an iOS-style activity indicator that spins clockwise.
            const
- CupertinoActivityIndicator.partiallyRevealed({Key? key, Color? color, double radius = _kDefaultIndicatorRadius, double progress = 1.0})
- 
          Creates a non-animated iOS-style activity indicator that displays
a partial count of ticks based on the value of progress.
            const

during pull-to-refresh when the drag-down action shows one tick at a time as
the user continues to drag down.
