<code>View</code> is a
|
|
container that supports layout with flexbox, style, some touch handling, and
|
|
accessibility controls, and is designed to be nested inside other views and
|
|
to have 0 to many children of any type. <code>View</code> maps directly to the native
|
|
view equivalent on whatever platform react is running on, whether that is a
|
|
<code>UIView</code>, <code><div></code>, <code>android.view</code>, etc. This example creates a <code>View</code> that
|
|
wraps two colored boxes and custom component in a row with padding.</p><div class="prism language-javascript"><View style<span class="token operator">=</span><span class="token punctuation">{</span><span class="token punctuation">{</span>flexDirection<span class="token punctuation">:</span> <span class="token string">'row'</span><span class="token punctuation">,</span> height<span class="token punctuation">:</span> <span class="token number">100</span><span class="token punctuation">,</span> padding<span class="token punctuation">:</span> <span class="token number">20</span><span class="token punctuation">}</span><span class="token punctuation">}</span><span class="token operator">></span>
