Flexbox is designed to provide a consistent layout on different screen sizes.</p>
|
||
<p>You will normally use a combination of <code>flexDirection</code>, <code>alignItems</code>, and <code>justifyContent</code> to achieve the right layout.</p>
|
||
<blockquote>
|
||
<p>Flexbox works the same way in React Native as it does in CSS on the web, with a few exceptions. The defaults are different, with <code>flexDirection</code> defaulting to <code>column</code> instead of <code>row</code>, and the <code>flex</code> parameter only supporting a single number.</p>

|

<p>Adding <code>flexDirection</code> to a component's <code>style</code> determines the <strong>primary axis</strong> of its layout. Should the children be organized horizontally (<code>row</code>) or vertically (<code>column</code>)? The default is <code>column</code>.</p>

|

<p>Adding <code>alignItems</code> to a component's style determines the <strong>alignment</strong> of children along the <strong>secondary axis</strong> (if the primary axis is <code>row</code>, then the secondary is <code>column</code>, and vice versa). Should children be aligned at the start, the center, the end, or stretched to fill? Available options are <code>flex-start</code>, <code>center</code>, <code>flex-end</code>, and <code>stretch</code>.</p>
|
||
<blockquote>
|
||
<p>For <code>stretch</code> to have an effect, children must not have a fixed dimension along the secondary axis. In the following example, setting <code>alignItems: stretch</code> does nothing until the <code>width: 50</code> is removed from the children.</p>

<p>We've covered the basics, but there are many other styles you may need for layouts. The full list of props that control layout is documented <a href="/react-native/docs/0.47/layout-props">here</a>.</p>

<p>We're getting close to being able to build a real application. One thing we are still missing is a way to take user input, so let's move on to <a href="/react-native/docs/0.47/handling-text-input">learn how to handle text input with the TextInput component</a>.</p>
