Error:Exception in
HostObject::get(propName:RNFirebase):

import { 
    Flatlist, 
    Text,
    TextInput,
    TouchableHighlight, 
    Image,
    View } from 'react-native';
import firebase from 'react-native-firebase';

export default class test extends Component {
    constructor(props){
        super(props);
        this.state = ({
            todoTask: [],
            newTaskName: '',
            loading: false
        });
        this.ref = firebase.firestore().collection('todo');
    }
    onPressAdd = …
