title: React Native: "Auto" width for text node
body: <p>I have a text element inside a view:</p>
  
  <p><code>&lt;View&gt;&lt;Text&gt;hello world foo bar&lt;/Text&gt;&lt;/View&gt;</code></p>
  
  <p>as part of a flex grid.</p>
  
  <p>I want this view to have an auto width based on the content i.e. length of the text.</p>
  
  <p>How do I achieve this?</p>
