Layers events

[sylvain258]

Hello,
I would like to create an event on a layer. I am looking for having the same result like "map.on('click', 'mylayer') ...." in JS. I found few tutos on website, it is impossible to reproduce the project. On "Filter" tutorial, we have :

  const [hoverInfo, setHoverInfo] = useState(null); 

  const onHover = useCallback(event => {
    const county = event.features && event.features[0];
    setHoverInfo({
      longitude: event.lngLat.lng, // => Un littéral d'objet peut uniquement spécifier des propriétés connues, et 'longitude' n'existe pas dans le type '(prevState: null) => null'.ts(2353)
      latitude: event.lngLat.lat,
      countyName: county && county.properties.COUNTY
    });
  }, []);

  const selectedCounty = (hoverInfo && hoverInfo.countyName) || '';
  const filter = useMemo(() => ['in', 'COUNTY', selectedCounty], [selectedCounty]);

My problem is line 6, with the setter setHoverInfo.

Thanks
