title: How to display .9.png format of a picture in flutter?
body: <p>Here is my code:</p>
  
  <pre><code>new Image.asset('images/launcher/border_highlight.9.png', fit: BoxFit.fill)));
  </code></pre>
  
  <p>When I change the width and height of the image, it has a poor display effect, but show normal in native android.</p>
  
  <p>Does flutter not support .9 picture? Is there another way to achieve the same effect?</p>
