title: Displaying the image in Flutter works once
body: <p>I have a problem with flutter <code>Image.assets</code>, when I set image in the file and set it in the asset like that :</p>
  <p>`flutter:
  uses-material-design: true
  assets:</p>
  <ul>
  <li>images/facebook.png`</li>
  </ul>
  <p>and when I put it in my code :</p>
  <pre><code>Center(
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: &lt;Widget&gt;[
          Image.asset(
            &quot;images/facebook.png&quot;
  
          ),
          Text(
            '$_counter',
            style: Theme.of(context).textTheme.display1,
          ),
        ],
      ),
    ),
  </code></pre>
  <p>and run it , it works well
  but the second time I run code , it not displaying
  and this the error I get :</p>
