Return address by geolocation - react-native

Question

I have this code to return the address:
const geo = {
getGeocode: (latitude, longitude) => {
axios.get('https://maps.googleapis.com/maps/api/geocode/json?address='+ latitude +','+ longitude + __API_KEY__)
.then(response => {
console.log(response);
return response.data.results[0].formatted_address
}).catch((error) => {
console.log( error.message )
});
return 'Error geocode'
},
getGeolocation: () => {
navigator.geolocation.getCurrentPosition(
(position) => {
console.log(position);
return geo.getGeocode(position.coords.latitude,position.coords.longitude);
},
(error) => console.log( error.message ),
{ enableHighAccuracy: true, timeout: 20000 },
);
return 'Error geolocation';
},
};
export default geo;
However every time I execute
import geolocation from './geolocation';
export default class App extends Component {
render() {
return (
<View style={{ flexGrow: 1, alignItems: 'center', justifyContent: 'center' }}>
<Text>Address: {geolocation.getGeolocation()}</Text>
</View>
);
}
}
this returns the Error geolocation
It returns on console the response with the address all right
I've tried it in many ways, and within what I know it should be returning the address correctly
[EDIT]
I tried this code too:
export const geo = {
var: address = '...',
getGeocode: (latitude, longitude) => {
axios.get('https://maps.googleapis.com/maps/api/geocode/json?address='+ latitude +','+ longitude + __API_KEY__)
.then(response => {
console.log(response);
response.data.results[0].formatted_address;
}).catch((error) => {
console.log( error.message )
});
return 'Error geocode';
},
getGeolocation: () => {
navigator.geolocation.getCurrentPosition(
(position) => {
console.log(position);
geo.getGeocode(position.coords.latitude, position.coords.longitude);
},
(error) => console.log( error.message ),
{ enableHighAccuracy: true, timeout: 20000 },
);
return address;
},
};
I return the address correctly, however I can not pass the value of response.data.results[0].formatted_address to variable address
How can I do this?
