CupertinoPopupSurface class
Rounded rectangle surface that looks like an iOS popup surface, e.g., alert dialog and action sheet.
A CupertinoPopupSurface can be configured to paint or not paint a white color on top of its blurred area. Typical usage should paint white on top of the blur. However, the white paint can be disabled for the purpose of rendering divider gaps for a more complicated layout, e.g., CupertinoAlertDialog. Additionally, the white paint can be disabled to render a blurred rounded rectangle without any color (similar to iOS's volume control popup).
