Camera

Most of the logic when taking photos can be abstracted when using react-native-camera, so we will focus on using this module in our component and making sure we connect it to our app's state through Redux actions:

/*** src/screens/Camera ***/

import React, { Component } from 'react';
import {
  Dimensions,
  StyleSheet,
  Text,
  TouchableHighlight,
  View
} from 'react-native';
import { Button, Icon } from 'native-base';
import Camera from 'react-native-camera';
import { bindActionCreators } from 'redux';
import { connect } from 'react-redux';
import * as Actions from '../actions';

class CameraScreen extends Component {
  static navigationOptions = {
    tabBarIcon: ({ tintColor }) => (
      <Icon name='camera' style={{fontSize: 40, color: tintColor}}/>
    ),
  };

  render() {
    return (
      <View style={styles.container}>
        <Camera
          ref={(cam) => {
            this.camera = cam;
          }}
          style={styles.preview}
          aspect...
