Hi,

I am getting the following error when I try to use react-native-geocoder:

TypeError: TypeError: undefined is not an object (evaluating 'RNGeocoder.geocodeAddress')

The code snippet I am using to test the geocoder is below:

mapAddress = (address) => { Geocoder.geocodeAddress(address).then(res => { console.log(res)} ).catch(err => {console.log(err)}) }

<View style={[{flex: 0.30, height: 35, marginVertical: 5, marginHorizontal: 4, alignItems: 'center', backgroundColor: '#1abc9c',borderRadius: 15}]}>
<Button title="Map" color="white" onPress={() => this.mapAddress('New York')}/>

Any help is really appreciated. I m using expo to develop this hybrid react-native app.
