I cannot figure out how to call fitBounds() on the Leaflet map.
Basically, I am trying to display multiple markers on the map and have the view adjust accordingly (zoom in, zoom out, fly to, etc.). i also saw some example How do you call fitBounds() when using leaflet-react? and i tried to implement but it did not work. Here is my code that i tried.
import React, { createRef, Component } from "react";
import {
Map,
TileLayer,
Marker,
Popup
} from "react-leaflet";
import L from "leaflet";
import Header from "../Layout/Header";
import Card from "@material-ui/core/Card";
import CardContent from "@material-ui/core/CardContent";
import Typography from "@material-ui/core/Typography";
import "leaflet/dist/leaflet.css";
export class Mapp extends Component {
constructor(props) {
super(props);
this.state = {
map: [],
open: false,
bounds: null,
center: [35.000074, 104.999927]
};
this.mapRef = createRef();
this.groupRef = createRef();
}
toggleHiddden1() {
this.setState({
open: false
});
async componentDidMount() {
try {
await fetch(`https://coronaviva.herokuapp.com/api/1/infected/data/`, {
method: "GET",
headers: {
Accept: "application/json",
"Content-Type": "application/json",
Authorization: "Bearer F9bQK456iUpJVZJLTZsMEKhhENqnGJ"
}
})
.then(map => map.json())
.then(map => {
this.setState({
map
});
});
} catch (err) {
console.log(err);
}
let mapInst = this.refs.map.leafletElement.fitBounds;
console.log(mapInst); // i tried this but this not working.
}
// centerUpdated(center) {
// this.center = center;
// }
// boundsUpdated(bounds) {
// this.bounds = bounds;
// }
render() {
const { map } = this.state;
const pointerIcon = new L.Icon({
iconUrl:
"https://icons.iconarchive.com/icons/paomedia/small-n-flat/512/map-marker-icon.png",
iconAnchor: [25, 40],
iconSize: [50, 50]
});
return (
