[React Native] Complete the Notes view

In this final React Native lesson of the series we will finalize the Notes view component and squash a few bugs in the code.

import firebase from ‘firebase‘;
import React from ‘react‘;
import {
    View,
    StyleSheet,
    Text,
    ListView,
    TextInput,
    TouchableHighlight
} from ‘react-native‘;
import Badge from ‘./Badge‘;
import Divdir from ‘./Helpers/divdir‘;

var styles = StyleSheet.create({
    container: {
        flex: 1,
        flexDirection: ‘column‘
    },
    buttonText: {
        fontSize: 18,
        color: ‘white‘
    },
    button: {
        height: 60,
        backgroundColor: ‘#48BBEC‘,
        flex: 3,
        alignItems: ‘center‘,
        justifyContent: ‘center‘
    },
    searchInput: {
        height: 60,
        padding: 10,
        fontSize: 18,
        color: ‘#111‘,
        flex: 10
    },
    rowContainer: {
        padding: 10
    },
    footerContainer: {
        backgroundColor: ‘#E3E3E3‘,
        alignItems: ‘center‘,
        flexDirection: ‘row‘
    }
});
