title: How to pass a parameter in react native navigator?
body: <p>I tried an example of React Native Navigator:</p>
  
  <pre><code>const StudentStackNav = StackNavigator({
    Home: {
       screen: StudentLogin,
      }
  });
  </code></pre>
  
  <p>How do I pass a parameter to StudentStackNav and pass it to StudentLogin?</p>
  
  <p>I have tried <code>&lt;StudentStackNav name='Lucy'&gt;</code> but <code>this.props.name</code> is not available in <code>Home</code>.</p>
