        primarySwatch: Colors.blue,
      ),
      home: SimpleHiddenDrawer(
        menu: Menu(),
        screenSelectedBuilder: (position,controller) {
          
          Widget screenCurrent;
          
          switch(position){
            case 0 : screenCurrent = Screen1(); break;
            case 1 : screenCurrent = Screen2(); break;
            case 2 : screenCurrent = Screen3(); break;
          }
          
          return Scaffold(
            backgroundColor: backgroundColorContent,
            appBar: AppBar(
              leading: IconButton(
                  icon: Icon(Icons.menu),
                  onPressed: () {
                    controller.toggle();
                  }),
            ),
            body: screenCurrent,
          );
          
        },
      ),
    );
  }
}

class Menu extends StatefulWidget {
  @override
  _SecondSreenState createState() => _MenuState();
}

class _MenuState extends State<SecondSreen> {

  SimpleHiddenDrawerController controller;

  @override
  void didChangeDependencies() {
    controller = SimpleHiddenDrawerController.of(context);
    super.didChangeDependencies();
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      width: double.maxFinite,
      height: double.maxFinite,
      color: Colors.cyan,
      padding: const EdgeInsets.all(8.0),
      child: Center(
        child: Column(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            RaisedButton(
              onPressed: () {
                controller.setSelectedMenuPosition(0);
              },
              child: Text("Menu 1"),
            ),
            RaisedButton(
              onPressed: () {
                controller.setSelectedMenuPosition(1);
              },
              child: Text("Menu 2"),
            )
          ],

      ),
    );
  }
}

Actions

This actions is only accessible by the children of HiddenDrawerMenu or SimpleHiddenDrawer.

Select item menu

SimpleHiddenDrawerController.of(context).setSelectedMenuPosition(0);

Toggle menu (if opened will close, if closed will open)

SimpleHiddenDrawerController.of(context).toggle();

Open

SimpleHiddenDrawerController.of(context).open();

Close

SimpleHiddenDrawerController.of(context).close();

Listen selected position

final controller = SimpleHiddenDrawerController.of(context);
controller.addListener((){
  print(controller.position);
});

Listen to menu status (closed,opening,open,closing)

final controller = SimpleHiddenDrawerController.of(context);
controller.addListener((){
  print(controller.state);
});

If you want to use only the widget responsible for the animation, it is now available as AnimatedDrawerContent

AnimatedDrawerController controller = AnimatedDrawerController(
  vsync: this,
  animationCurve:Curves.decelerate,
  duration:const Duration(milliseconds: 350,
);

return AnimatedDrawerContent(
  controller: controller,
  whithPaddingTop: false, //(optional) default = false // Add padding top in de gesture equals Heigth of the AppBar
  whithShadow: false, //(optional) default = false
  isDraggable: true, //(optional) default = true
  child: Screen(),
);

You can control actions by controller such as:

controller.toggle() // Open or Close
controller.open()
controller.close()
controller.move(percent) // moves to a specific position from 0 to 1 (0 = fully enclosed, 1 = fully opened)
