How to reach 'measure-start', 'measure-end' events?

Hi,

I'm trying to find the 'measure-start', 'measure-end' events that the new measurement widgets can have.

For example;

measurement.on('measure-start', function (event) { console.log(event); });

But It doesn't work that way.

The 4.x Measure widget doesn't have events. Take a look at this post:

How would you then read out the current measurement distance/area from the tool? My case is that using "distance" we need to display the value somewhere else in the UI.

I was hoping for something along the lines of

useEffect(() => { const measureTool = new Measurement({ linearUnit: 'metric', areaUnit: 'metric' }); measureTool.on('measurement-update', (event: { distance: number }) => { console.log(event.distance); }); setMeasurement(measureTool); }, []);
