title: How to position 3 buttons in StackLayout equal width
body: <p>Anyone know how to position 3 buttons in <code>StackLayout</code> with equal width?  I have it working with <code>Grid</code> with</p>
  <pre><code>&lt;Grid x:Name=&quot;MyGrid&quot; Grid.Row=&quot;0&quot; BindingContext=&quot;{x:Reference Name=Button1}&quot;  HeightRequest=&quot;{Binding Width}&quot;&gt;
  </code></pre>
  <p>I would like to find a way to show 3 buttons on same line  with same width equally without a <code>Grid</code>
  For example all 3 buttons of equal length fitting across horizontally in <code>StackLayout</code></p>
  <p>[   Button 1   ]  [   Button 222   ]  [   Button 333333   ]</p>
