title: Change Footer Color in Flutter. (persistentFooterButtons)
body: <p>I have a <code>persistentFooterButtons</code> option for my <code>Scaffold</code>.</p>
  <pre><code>persistentFooterButtons: [
          FloatingActionButton(
              heroTag: &quot;editself&quot;,
              child: Icon(Icons.edit),
              onPressed: () {
                print(InterfaceViewRoute);
                Navigator.pushNamed(context, InterfaceViewRoute, arguments: &quot;-1&quot;);
              }),
          FloatingActionButton(
            heroTag: &quot;scanneredit&quot;,
            child: Icon(Icons.qr_code_scanner_rounded),
            onPressed: () =&gt; _scan(),
          ),
        ],
      );
  </code></pre>
  <p>But now the whole background is filled there. See image:</p>

  <p>Is there a way to make this background transparent so that you can see the list all the way down</p>
