title: Change the size of a checkbox with Material UI
body: <p>I'm currently having trouble changing the size of a checkbox to a custom one using Material UI. The code is the following</p>
  
  <pre><code>&lt;Checkbox
      label="Check this box"
      onChange={() =&gt; dispatch(switchCompleted())}
      checked={status.showCompleted}
      style={{
        color: "#00e676",
        width: 36,
        height: 36
      }}
    /&gt;
  </code></pre>
  
  <p>I also tried using <code>size: 'medium'</code> but the size of the checkbox stays small. Does anyone know how to solve this?</p>
