title: String xml file in Flutter
body: <p>In flutter string text are directly set to the <code>TextField</code> widget like:</p>
  
  <pre><code>new Text('Hello,  How are you?')
  </code></pre>
  
  <p>Is correct way ? or we can maintain all string in one file and use it like:</p>
  
  <pre><code>&lt;string name="name_hint"&gt;Hello, How are you?&lt;/string&gt;
  </code></pre>
  
  <p>Is it possible ?</p>
