Custom button on the leaflet map with React-leaflet version3 - reactjs

Question

I'm a new leaflet learner with React typescript. Want to create a custom button on the map. On clicking the button a popup will appear. I saw many example but they are all based on older version and I also tried to create my own but no luck. The documentation also not providing much help. Even a functional custom control component is also very effective for my app. Any help on this will be much appreciated. Here is my code,
Custom button
import React, { Component } from "react";
import { useMap } from "react-leaflet";
import L, { LeafletMouseEvent, Map } from "leaflet";
class Description extends React.Component<{props: any}> {
createButtonControl() {
const MapHelp = L.Control.extend({
onAdd: (map : Map) => {
const helpDiv = L.DomUtil.create("button", ""); //how to pass here the button name and
//other property ?
//a bit clueless how to add a click event listener to this button and then
// open a popup div on the map
}
});
return new MapHelp({ position: "bottomright" });
}
componentDidMount() {
const { map } = this.props as any;
const control = this.createButtonControl();
control.addTo(map);
}
render() {
return null;
}
}
function withMap(Component : any) {
return function WrappedComponent(props : any) {
const map = useMap();
return <Component {...props} map={map} />;
};
}
export default withMap(Description);
The way I want to call it
<MapContainer
center={defaultPosition}
zoom={6}
zoomControl={false}
>
<Description />
<TileLayer
attribution="Map tiles by Carto, under CC BY 3.0. Data by OpenStreetMap, under ODbL."
url="https://cartodb-basemaps-{s}.global.ssl.fastly.net/light_all/{z}/{x}/{y}.png"
/>
<ZoomControl position={'topright'}/>
</MapContainer>

You're close. Sticking with the class component, you just need to continue creating your buttons instance. You can use a prop on Description to determine what your button will say and do:
<Description
title={"My Button Title"}
markerPosition={[20.27, -157]}
description="This is a custom description!"
/>
In your decsription's createButtonControl, you're almost there. You just need to fill it out a bit:
createButtonControl() {
const MapHelp = L.Control.extend({
onAdd: (map) => {
const helpDiv = L.DomUtil.create("button", "");
this.helpDiv = helpDiv;
// set the inner content from the props
helpDiv.innerHTML = this.props.title;
// add the event listener that will create a marker on the map
helpDiv.addEventListener("click", () => {
console.log(map.getCenter());
const marker = L.marker()
.setLatLng(this.props.markerPosition)
.bindPopup(this.props.description)
.addTo(map);
marker.openPopup();
});
// return the button div
return helpDiv;
}
});
return new MapHelp({ position: "bottomright" });
}

There's a million ways to vary this, but hopefully that will get you going.
