title: Show flyout using BottomAppBar
body: <p>I'm trying to show a simple Flyout (with informational content) when a AppBarToggleButton within BottomAppBar is pressed, but my solution doesn't work. :(</p>
  
  <p>This is my code:</p>
  
  <pre><code>&lt;Page.BottomAppBar&gt;
          &lt;CommandBar&gt;
              &lt;AppBarToggleButton x:Uid="MapPageAppBarLegend" Label="" Icon="List"&gt;
                  &lt;FlyoutBase.AttachedFlyout&gt;
                      &lt;Flyout&gt;
                          &lt;TextBlock Text="Informations here..."/&gt;
                      &lt;/Flyout&gt;
                  &lt;/FlyoutBase.AttachedFlyout&gt;
              &lt;/AppBarToggleButton&gt;
          &lt;/CommandBar&gt;
  &lt;/Page.BottomAppBar&gt;
  </code></pre>
