import React, { Component } from 'react';
import { Map, TileLayer, Marker, Popup } from 'react-leaflet';
import DivIcon from 'react-leaflet-div-icon';
export default class UserLocationExample extends Component {
  constructor() {
    super();
    this.state = {
      hasLocation: false,
      latlng: {
        lat: 51.505,
        lng: -0.09,
      },
    };
  }

  handleClick() {
    this.refs.map.leafletElement.locate();
  }

  handleLocationFound(e) {
    this.setState({
      hasLocation: true,
      latlng: e.latlng,
    });
  }

  render() {
    const marker = this.state.hasLocation
      ? (
        <DivIcon position={this.state.latlng}>
          <svg className="user-location" viewBox="0 0 120 120" version="1.1"
            xmlns="http://www.w3.org/2000/svg">

          </svg>
        </DivIcon>
      )
      : null;

    return (
      <Map
        center={this.state.latlng}
        length={4}
