Here you have a basic sample: 

@override
  Widget build(BuildContext context) {
    return Scaffold(
      endDrawer: Drawer(),
      appBar: AppBar(),
      body: Builder(
        builder: (context) {
          return Center(
            child: RaisedButton(
              child: Text("open drawer"),
              onPressed: () {
                Scaffold.of(context).openEndDrawer();
              },
            ),
          );
        },
      ),
    );
  }

Or you can use GlobalKey of ScaffoldState:


  GlobalKey<ScaffoldState> _key = new GlobalKey<ScaffoldState>();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      key: _key,
      endDrawer: Drawer(),
      appBar: AppBar(),
      body: Center(
        child: RaisedButton(
          child: Text("open drawer"),
          onPressed: () {
            _key.currentState.openEndDrawer();
          },
        ),
      ),
    );
  }
}

create a scaffold key then give it your scaffold widget

GlobalKey<ScaffoldState> _scaffoldKey = new GlobalKey<ScaffoldState>();

then, to open drawer

_scaffoldKey.currentState.openDrawer()

or 

_scaffoldKey.currentState.openEndDrawer()
