undefined is not an object (evaluating 'FIRAnalytics.setEnabled)


using react-native-firbase-analytics `1.0.6`
using react-native `0.32.0`

```javascript
import React, {
Component,
PropTypes,
} from 'react';
import {
View,
StyleSheet,
ScrollView,
Alert,
AlertIOS,
InteractionManager,
} from 'react-native';
import Analytics from 'react-native-firebase-analytics';
import Dialog from 'react-native-dialog';

// ...

export default class CartPage extends Component {
constructor(props) {
super(props);
this.state = {
renderPlaceholderOnly: false,
};
props.dispatch(fetchCartInfo(props.serviceType));
props.dispatch(fetchMyCouponCount());
}

componentWillMount() {
console.log(Analytics.setEnabled);
Analytics.setEnabled(false);
}
```

I trying run this Component. occurring error `undefined is not an object (evaluating 'FIRAnalytics.setEnabled)`

but console is that.
```
02-04 19:52:28.531 2896 2959 I ReactNativeJS: [Function: setEnabled]
02-04 19:52:29.127 2896 2959 E ReactNativeJS: undefined is not an object (evaluating 'FIRAnalytics.setEnabled')
```

Naturally, I included google-service.json file as well. and already run `rnpm link` what the hell?
I think `NativeModules.RNFIRAnalytics` is undefined.
What should I check?
