Complete example with Geolocation API.

As I said at comment; you don't need to Google API to get current coordinates of device. You can use Geolocation API

import React, { Component } from 'react';
import { View, Text } from 'react-native';

class FindMyLocationExample extends Component {
  constructor(props) {
    super(props);

    this.state = {
      latitude: null,
      longitude: null,
      error: null,
    };
  }

  componentDidMount() {
    navigator.geolocation.getCurrentPosition(
      (position) => {
        this.setState({
          latitude: position.coords.latitude,
          longitude: position.coords.longitude,
          error: null,
        });
      },
      (error) => this.setState({ error: error.message }),
      { enableHighAccuracy: true, timeout: 10000, maximumAge: 1000 },
    );
  }

  render() {
    return (
      <View style={{ flexGrow: 1, alignItems: 'center', justifyContent: 'center' }}>
        <Text>Latitude: {this.state.latitude}</Text>
        <Text>Longitude: {this.state.longitude}</Text>
        {this.state.error ? <Text>Error: {this.state.error}</Text> : null}
      </View>
    );
  }
}

Use this Code to get Current latitude and longitude:

navigator.geolocation.getCurrentPosition(
(position) => {
    console.log('lat',position.coords.latitude);
    console.log('lng',position.coords.longitude);
    //Your Code
    // ( DO fetch call to get address from lat and lng
    // https://maps.googleapis.com/maps/api/geocode/json?key= 
    <\API_KEY_HERE>&latlng="latitude","longitude"&sensor=true )
},
(error) => this.setState({ error: error.message }),
   { enableHighAccuracy: true, timeout: 20000, maximumAge: 1000 },
);
