Answer 1

To open the drawer do this

Scaffold(
    appBar: AppBar(
       automaticallyImplyLeading: false
    ), 
    drawer: Drawer(), 
    body: ...
);

But if you want to change the drawer button icon do this instead

Scaffold(
    appBar: AppBar(
       leading: Builder(
          builder: (context) => IconButton(
             padding: EdgeInsets.zero,
             icon: //your icon,
             onPressed: () => Scaffold.of(context).openDrawer()
          ), 
       ), 
    ), 
    drawer: Drawer(), 
    body: ...
);
