title: How do I stack widgets overlapping each other in flutter
body: <p>I need to stack widgets like this:</p>
  <p><a href="https://i.stack.imgur.com/4AaeT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/4AaeT.png" alt="coins" /></a></p>
  <p>I wrote the code below. However the coins are coming one after another with some default padding. How can I get something like the image above?</p>
  <pre class="lang-dart prettyprint-override"><code>Row(
    children: &lt;Widget&gt;[
      Icon(
        Icons.monetization_on, size: 36.0, 
        color: const Color.fromRGBO(218, 165, 32, 1.0),
      ),
      Icon(
        Icons.monetization_on, size: 36.0,
        color: const Color.fromRGBO(218, 165, 32, 1.0),
      ),
    ],
  ),
  </code></pre>
