title: How can I change the Font Size and Weight for the Header in a Navigation Page?
body: <p>I can change the <code>Font Color</code> like this:</p>
  
  
  
  <pre class="lang-cs prettyprint-override"><code>var homePage = new NavigationPage(new HomePage())
  { 
     Title = "Home",
     Icon = "ionicons_2_0_1_home_outline_25.png",
     BarTextColor = Color.Gray,
  };
  </code></pre>
  
  <p>But is there a way to change the <code>Font Size</code> and <code>Weight</code> for the Title? I would like to change it for the <strong>iOS</strong> and <strong>Android</strong> platforms only. Hoping that someone knows of <code>Custom Renderer</code> code that can help me to do this.</p>
  
  <p>Note that this question is similar to my question on how to change the Font which has been answered here:</p>
