title: How to remove the content padding that the list tile comes with by default?
body: <p>I was working with a drawer which had a list of tiles. Each individual tile has an image and a text following it. So I put the above mentioned widgets in a row. To my surprise, I found that there is some unexplained padding between the text and the title. I am attaching a screenshot of a tile for better understanding :</p>

  <p>Any suggestion is welcome!. Thank you!.</p>
  
  <p>I have added <code>rowChildren</code> which is a list of widgets because my list tile title may contain text and some image :</p>
  
  <pre><code>child = new Container(
    child: new Column(
      children: &lt;Widget&gt;[
        new ListTile(
          dense: true,
          leading: new Image.asset(
                  leading,
                  color: Colors.white,
                )
          title: new Row(
            children: rowChildren,
          ),
        )
      ],
    ),
  );
  </code></pre>
  
  <p>and this is the flutter inspector screenshot corresponding to the image I shared :</p>

  <p>I added <code>debugPaintSizeEnabled=true</code> and got this :</p>
