final _scaffoldKey = GlobalKey<ScaffoldState>();
ScaffoldFactory _scaffoldFactory;
MaterialPalette _sampleColorPalette = MaterialPalette(
  primaryColor: Colors.teal,
  accentColor: Colors.pinkAccent,

  @override
  void onBackButtonPressed() {
    print("Scaffold Factory => onBackButtonPressed()");

  void initState() {
    super.initState();
    _initScaffoldFactory();
  }
  
  void _initScaffoldFactory() {
    _scaffoldFactory = ScaffoldFactory(
      scaffoldKey: _scaffoldKey,
      materialPalette: _sampleColorPalette,
    );
    _scaffoldFactory.scaffoldFactoryBehavior = this;

    _scaffoldFactory.init(
      backgroundType: BackgroundType.normal,
      appBarVisibility: false,
      floatingActionButtonVisibility: false,
      drawerVisibility: false,
      nestedAppBarVisibility: false,
      bottomNavigationBarVisibility: false,
    );
  }

  _scaffoldFactory.textTheme = Theme.of(context).textTheme;

  return _scaffoldFactory.build(_buildBody(context));
}

Widget _buildBody(BuildContext context) {
  // return your body widget    
}

Features

• Easily create a material interface with simple configurations.

buildAppBar	AppBar widget
buildNestedScrollView	NestedScrollView widget
buildBottomNavigationBar	BottomNavigationBar widget
buildBottomAppBar	BottomAppBar widget
buildFloatingActionButton	FloatingActionButton widget

 _scaffoldFactory.init(
      appBarVisibility: true,
      appBar: _scaffoldFactory.buildAppBar(
        titleVisibility: true,
        leadingVisibility: false,
        tabBarVisibility: false,

    );

or whenever you want in the build method of your state.

@override
Widget build(BuildContext context) {
  _scaffoldFactory.textTheme = Theme.of(context).textTheme;
  
  _scaffoldFactory.appBarVisibility = true;
  _scaffoldFactory.appBar = _scaffoldFactory.buildAppBar(
      titleVisibility: true,
      leadingVisibility: false,
      tabBarVisibility: false,
      titleWidget: Text('Scaffol Factory Example'),
