of just one screen. As soon as you add a second screen to your app, you will have to take into consideration how the user will navigate from one screen to the other.</p><p>You can use navigators to transition between multiple screens. These transitions can be typical side-to-side animations down a master/detail stack, or vertical modal popups.</p><h2><a class="anchor" name="navigator"></a>Navigator <a class="hash-link" href="docs/using-navigators.html#navigator">#</a></h2><p>React Native has several built-in navigation components, but for your first app you will probably want to use <code>Navigator</code>. It provides a JavaScript implementation of a navigation stack, so it works on both iOS and Android and is easy to customize.</p><p><img src="img/NavigationStack-Navigator.gif" alt=""></p><h3><a class="anchor" name="working-with-scenes"></a>Working with Scenes <a class="hash-link" href="docs/using-navigators.html#working-with-scenes">#</a></h3><p>At this point you should feel comfortable rendering all sorts of components in your app, be it a simple <code>View</code> with <code>Text</code> inside, or a <code>ScrollView</code> with a list of <code>Image</code>s. Together, these components make up a scene (another word for screen) in your app.</p><p>A scene is nothing other than a React component that is typically rendered full screen. This is in contrast to a <code>Text</code>, an <code>Image</code>, or even a custom <code>SpinningBeachball</code> component that is meant to be rendered as part of a screen. You may have already used one without realizing it - the <a href="docs/tutorial.html" target="_blank">"HelloWorldApp"</a>, the <a href="docs/flexbox.html" target="_blank">"FlexDirectionBasics"</a>, and the <a href="docs/using-a-listview.html" target="_blank">"ListViewBasics"</a> components covered earlier in the tutorial are all examples of scenes.</p><p>For simplicity's sake, let's define a simple scene that displays a bit of text. We will come back to this scene later as we add navigation to our app. Create a new file called "MyScene.js" with the following contents:</p><div class="prism language-javascript">import React<span class="token punctuation">,</span> <span class="token punctuation">{</span> Component <span class="token punctuation">}</span> from <span class="token string">'react'</span><span class="token punctuation">;</span>

A route is an object that contains information about a scene. It is used to provide all the context that the navigator's <code>renderScene</code> function needs to render a scene. It can have any number of keys to help distinguish your scene, and I happened to pick a single <code>title</code> key for the above example.</p><h4><a class="anchor" name="pushing-scenes-onto-the-stack"></a>Pushing scenes onto the stack <a class="hash-link" href="docs/using-navigators.html#pushing-scenes-onto-the-stack">#</a></h4><p>In order to transition to a new scene, you will need to learn about <code>push</code> and <code>pop</code>. These two methods are provided by the <code>navigator</code> object that is passed to your <code>renderScene</code> function above. They can be used, as you may have realized, to push and pop routes into your navigation stack.</p><div class="prism language-javascript">navigator<span class="token punctuation">.</span><span class="token function">push<span class="token punctuation">(</span></span><span class="token punctuation">{</span>

It displays two tappable components that call the <code>onForward</code> and <code>onBack</code> functions passed through its props, which in turn will call <code>navigator.push()</code> and <code>navigator.pop()</code> as needed.</p><p>Check out the <a href="docs/navigator.html" target="_blank">Navigator API reference</a> for more <code>Navigator</code> code samples, or read through the <a href="docs/navigation.html" target="_blank">Navigation guide</a> for other examples of what you can do with navigators.</p><h2><a class="anchor" name="high-five"></a>High Five! <a class="hash-link" href="docs/using-navigators.html#high-five">#</a></h2><p>If you've gotten here by reading linearly through the tutorial, then you are a pretty impressive human being.
