title: Align an image to top left in Flutter
body: <p>I am pretty new to flutter, and can't figure out how to align one of my children widgets containing an image. This is what I have tried so far:</p>
  
  <pre><code>@override
  Widget build(BuildContext context) {
    return Scaffold(
    appBar: AppBar(
      title: Text(widget.username),
      backgroundColor: new Color(0xFF24292E),
    ),
    body: Center(
      child: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        mainAxisSize: MainAxisSize.max,
        mainAxisAlignment: MainAxisAlignment.start,
        children: &lt;Widget&gt;[
          Image.asset(
            'assets/profile.png', width: 100.0, height: 100.0,
          ),
        ],
      ),
    ),
  );
  }
  </code></pre>
  
  <p>The image is staying in the center top of the screen however. How can I move it to the top left relative to the screen? Thanks.</p>
