title: How to center a cupertino icon in flutter?
body: <p>First of all, I have tried using Center(),
  With that out the way, it seems cupertino icons are off center</p>
  
  <pre><code>             IconButton(
                icon: const Icon(
                  CupertinoIcons.add_circled,
                  color: Colors.black,
                ),
                padding: const EdgeInsets.all(0),
                onPressed: () {}
                ),
  </code></pre>
  
  <p>wrapping the icon directly in a Center() widget doesnt change anything either I this is how it looks <a href="https://i.stack.imgur.com/lu1SF.png" rel="noreferrer"><img src="https://i.stack.imgur.com/lu1SF.png" alt="slightly off center"></a></p>
