title: Notch for Docked FloatingActionButton Missing in BottomAppBar
body: <h2>Once</h2>
  <p>You can <strong>dock</strong> a <em><code>FloatingActionButton</code></em> by specifying <code>floatingActionButtonLocation</code> in a <code>Scaffold</code> and using <code>BottomAppBar</code>.</p>
  <p>The <a href="https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/material/floating_action_button_location.dart#L64" rel="nofollow noreferrer">documentation</a> talks about a:</p>
  <blockquote>
  <p>&quot;notch&quot;</p>

  <h2>Now</h2>

  <pre><code>import 'package:flutter/material.dart';
  
  main() =&gt; runApp(MaterialApp(
    home: Scaffold(
      bottomNavigationBar: BottomAppBar(
        child: Container(
          height: 300.0,
          color: Colors.pinkAccent,
        ),
      ),
      floatingActionButtonLocation: FloatingActionButtonLocation.centerDocked,
      floatingActionButton: FloatingActionButton(onPressed: () {}),
    ),
  ));
  </code></pre>
  <p>With <em><strong>Flutter</strong> version</em> <code>0.5.6</code>, I am unable to recreate the notch. The second image and the code below it belong together.</p>
  <p>Is this <em>an issue/bug</em> or is there anything I can, now, do about it?</p>
