title: how to multi-check react-native-element's checkbox?
body: <p>I'm a newbie with React Native, I'm building a quiz application with multiple choices by using "react-native-elements" to generate the checkboxes. But I don't know how to control the multi-check function. I have searched and found a solution <a href="https://stackoverflow.com/questions/43867821/how-to-render-multi-components-and-set-individual-status-in-react-native/47025846#47025846">here</a>.</p>
  
  <p>But I still don't understand that when using Michael Peyer solution, which is the state I should define on the constructor function to adapt this solution?</p>
  
  <pre><code>  constructor(props) {
      super(props);
      this.state = ??;
    }
  </code></pre>
