No context provided: useleafletcontext() can only be used in a descendant of

The error message you mentioned suggests that the useLeafletContext() hook can only be used within a component that is a descendant of the <MapContainer> component in the Leaflet library.

In order to use useLeafletContext(), you need to ensure that you have a <MapContainer> component wrapping your <Map> component or any other components that may use this hook. This is because useLeafletContext() relies on the context provided by the <MapContainer> component to work properly.

Here’s an example of how you can structure your code to use useLeafletContext() properly:


import React from 'react';
import { MapContainer, TileLayer, Marker } from 'react-leaflet';
import { useLeafletContext } from 'react-leaflet';

const MyComponent = () => {
  const context = useLeafletContext();
  const map = context.map;
  const layerControl = context.layerControl;
  const layerContainer = context.layerContainer;
  // Rest of your component logic
  return (
    <MapContainer center={[51.505, -0.09]} zoom={13} style={{ height: '100vh' }}>
      <TileLayer
        url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
        attribution="&copy; OpenStreetMap contributors"
      />
      <Marker position={[51.505, -0.09]}></Marker>
    </MapContainer>
  );
};


In the example above, the MyComponent component uses the useLeafletContext() hook to access the Leaflet context variables such as the map, layer control, and layer container. This hook works because the MyComponent component is a descendant of the <MapContainer> component.

Make sure your code follows a similar structure, with the <MapContainer> component wrapping the content where you want to use useLeafletContext().
