@override
Widget build(BuildContext context) {
  return MaterialApp(
    title: 'Backdrop Demo',
    home: BackdropScaffold(
      appBar: BackdropAppBar(
        title: Text("Navigation Example"),
        actions: <Widget>[
          BackdropToggleButton(
            icon: AnimatedIcons.list_view,
          )
        ],
      ),
      stickyFrontLayer: true,
      frontLayer: _pages[_currentIndex],
      backLayer: BackdropNavigationBackLayer(
        items: [
          ListTile(title: Text("Widget 1")),
          ListTile(title: Text("Widget 2")),
        ],
        onTap: (int position) => {setState(() => _currentIndex = position)},
      ),
    ),
  );
}
