PopoverOverlayWidgetState class

State class for PopoverOverlayWidget managing popover positioning and lifecycle.

Handles dynamic positioning, anchor tracking, size constraints, and animation for popover overlays. Its lifecycle (close/closeLater) and live configuration updates are driven externally by the OverlayPopoverEntry (an OverlayCompleter) returned from PopoverOverlayHandler.show.
