[question] Change Center of map if state changes

[FleetAdmiralJakob]

How can I make that if I change a state that stores the coordinates in a higher component and pass the state as a prop to the map component. How can I make that the center of the map changes if the state changes?

use useRef hook.

//Code
const mapRef = useRef(null);

useEffect(() => {
if (mapRef.current && lat !== undefined && lng !== undefined) {
mapRef.current.setView([lat, lng], mapRef.current.getZoom());
}
}, [lat, lng]);

<MapContainer
center={[lat, lng]}
zoom={13}
ref={mapRef}
>{...your code}

//Code

Explanation:

1. Use useRef hook and create an instance reference of the map.
2. use useEffect hook to update the map position whenever lat or lng values changes as they are dependencies and use above code. I believe you can understand the code in useEffect hook. If not, reply to me, I'll explain
3. Add a reference in the MapContainer Component using ref tag and done.
