Snapping Enforcement/Confirmation 4.19

FrederickPowers

Is there a way to test whether a point created with the Sketch or Editor widgets has been placed as a snapped point to a particular feature?  The feature and vertex highlighting are very useful, but I'm looking for a way to enforce snapping to a particular feature and notify the user if a point wasn't placed as a snapped point.

You could use various methods of the geometryEngine to validate that geometries intersect or that a vertex matches a point

It might require breaking up polygons -> polylines -> points, but should be doable.
