CupertinoMagnifier class

A RawMagnifier used for magnifying text in cases where a user's finger may be blocking the point of interest, like a selection handle.

CupertinoMagnifier is a wrapper around RawMagnifier that handles styling and transitions.

This magnifying glass is useful for scenarios on mobile devices where the user's finger may be covering part of the screen where a granular action is being performed, such as navigating a small cursor with a drag gesture, on an image or text.

Constructors
