Listening for measurefinish event

[matbeseris]

I'm pretty new to R and I'm trying to simply listen for the measurefinish event and do stuff with the data from it, however I can't find any R examples anywhere.

The code I have so far:

observeEvent(input$measurefinish, {
    print("user finished measurement")
})

I'm pretty sure it needs to be something other than input but I just don't know what it would be

Any help would be super appreciated!

For ReactJS this could be code could be used. Maybe it is helpful.

      map.on('measurefinish', function(evt) {
        print('this is measurement area')
        print(evt)
      });
