Property 'map' does not exist on type 'MapView'

I am using typescript and react-native-maps to create a react-native application. I am following one of their examples given here.

Before I try to call the methods I have to create a ref as shown in the example but I am getting the following error.

"Property 'map' does not exist on type 'Map'"

Here's my code.

import React, { Component } from "react";
import MapView, { Marker } from "react-native-maps";

export default class Map extends Component {
  constructor(props: any) {
    super(props);

    this.state = {
      region: {
        latitude: LATITUDE,
        longitude: LONGITUDE,
        latitudeDelta: LATITUDE_DELTA,
        longitudeDelta: LONGITUDE_DELTA
      },
      coordinate: {
        latitude: LATITUDE,
        longitude: LONGITUDE
      }
    };
  }

  render() {
    return (
      <MapView
        // Getting that error in this line
        ref={map => { this.map = map; }}
        style={{ flex: 1 }}
        region={this.state["region"]}
      >
        <Marker coordinate={this.state["coordinate"]} />
      </MapView>
    );
  }
}

I tried some solutions that were given here but i suspect its not a solution for react-native?
