React google maps url undefined - reactjs

Question

I am trying to update the viewport bounds based on the markers coords in my react google maps component.
However when I call the following line in componentWillMount()
const bounds = new google.maps.LatLngBounds();
I get an error that says google is not defined.
To resolve this I have tried
(1) Adding the google maps script tag to the index.html
(2) Adding the line
/* eslint-disable no-undef */
to the top of my file.
(3) Adding withScriptjs, withGoogleMap inside my compose() but it produces an error that says the googleMapUrl and the loading element is not defined. To solve this I tried doing
<MapSearchBox
googleMapURL="https://maps.googleapis.com/maps/api/js?key=APIKEY&v=3.exp&libraries=geometry,drawing,places"
loadingElement={<div style={{ height: `100%` }} />}
isMarkerShown={this.state.isMarkerShown}
onMarkerClick={this.handleMarkerClick}
/>
but this did not work.
(4) Added /* global google */ to the top of my file
Also some other small changes but nothing sticks.
Please give some suggestions!

Add Google Map url script in index.html
<script src="https://maps.googleapis.com/maps/api/js?key=APIKEY=3.exp&libraries=geometry,drawing,places></script>
