QUESTION
I am using react-leaflet and Leaflet.Path.Drag to drag GeoJSON. I would need to keep GeoJSON coordinations in React state. The issue is that updated coordinations on dragEnd
are not corrent and GeoJSON position is not correct after dragging.
App.js
...ANSWER

QUESTION
I am using React Leaflet to render Leaflet map and its GeoJSON component to render polygons. I am trying to implement dragging multiple polygons together at once, as a group.

You should consider whether you would like to disable the FreeDraw after this
, using the option leaveModeAfterCreate:true
as the user may get additional polygons when dragging
