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

The error message “useLeafletContext() can only be used in a descendant of ” is commonly encountered when using the React Leaflet library. This error occurs when the useLeafletContext hook is used outside of a component that is a descendant of the component provided by React Leaflet.

To fix this error, make sure that the component where you are using the useLeafletContext hook is wrapped inside a component. The component acts as a provider for the Leaflet context and should be the root component of your Leaflet map.

Here’s an example of how to use the useLeafletContext hook within a component that is a descendant of :

        
            import { MapContainer, useLeafletContext } from 'react-leaflet';
            
            const CustomComponent = () => {
                const context = useLeafletContext();
                
                // Use the Leaflet context here...
                
                return null;
            }
            
            const App = () => {
                return (
                    
                        
                    
                );
            }
        
    

In the example above, the CustomComponent is a descendant of the component and can safely use the useLeafletContext hook. The useLeafletContext hook will provide access to the Leaflet context, allowing you to interact with the Leaflet map API within the CustomComponent.
