title: Does using const in the widget tree improve performance?
body: <p>When creating a widget tree, will inserting <code>const</code> before static widgets improve performance?</p>
  
  <p>ie</p>
  
  <pre><code>child: const Text('This is some text');
  </code></pre>
  
  <p>vs</p>
  
  <pre><code>child: Text('This is some text');
  </code></pre>
  
  <p>I know that, with Dart 2, <code>const</code> is optional and will be inserted automatically is some places. Is this one of those situations? If it isn't, will using <code>const</code> reduce memory usage/improve performance?</p>
  
  <p>Thanks for your answers!</p>
