title: flutter: BoxShadow errors
body: <pre class="lang-dart prettyprint-override"><code>Container(
    decoration: BoxDecoration(
      boxShadow: BoxShadow(
        color: Colors.black,
        blurRadius: 5,
        spreadRadius: 6,
      ),
      color: Color.fromARGB(255, 255, 255, 255),
      border: Border(
        left: BorderSide(color: Colors.black, width: 10.0),
      ),
    ),
  )
  </code></pre>
  <p>What is wrong, why are there red lines under the Boxshadow? I watched a video and did exactly what he did. Where is the mistake?</p>
