ChartContextMenuHelper class

Helper for displaying a chart context menu as an application overlay.

Usage (from inside a chart's tap callback):

ChartContextMenuHelper.show(
  context,
  point: point,
  segment: null,
  position: globalTapPosition,
  onViewDetails: () { /* ... */ },
);

Only one menu is shown at a time; calling show again replaces the current menu. Calling hide is idempotent.
