title: Xamarin Forms Search Bar padding
body: <p>I am using the built in searchbar control in xamarin forms. It works fine for my implementation but I notice there is a small amount of whitespace on each side of the control. I see that i can modify margin to 0 but it does not change the whitespace. Here is what it looks like with a picker above it and a map below it:</p>
  
  <p><a href="https://i.stack.imgur.com/r8QNd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/r8QNd.png" alt="search bar"></a></p>
  
  <p>Here is my xaml</p>
  
  <p></p>
  
  <pre><code>    &lt;Picker x:Name="servicePicker" Title="Test" ios:Picker.UpdateMode="Immediately"  HorizontalOptions="FillAndExpand"&gt;
  
      &lt;/Picker&gt;
       &lt;SearchBar Margin="0" Placeholder="Enter a zip code" TextChanged="Handle_TextChanged"&gt;&lt;/SearchBar&gt;
          &lt;maps:Map Margin="0"
          x:Name="MyMap"
          IsShowingUser="true"
          MapType="Hybrid"
      /&gt;
  &lt;/StackLayout&gt;
  </code></pre>
  
  <p>I dont see any option for padding, how can i get rid of the whitespace? </p>
