Custom widget of app bar with a humburger menu as ElevatedButton with a Drawer doesn't work OnPressed - flutter

Question

I am facing a problem with my custom app bar. I would like it to have a drawer but it doesn't work. I just don't know how to make it being able to open.
It is a custom app bar widget named Pasek (which stands for top bar in my language).
It has a logo picture which on click moves you to the first page of the app.
Next to it there is humburger menu with a drawer but I do not know why it doesn't work. I click on it and nothing happens.
Any ideas?
class Pasek extends StatelessWidget with PreferredSizeWidget {
#override
Size get preferredSize => Size.fromHeight(50.0);
const Pasek({
Key? key,
}) : super(key: key);
#override
Widget build(BuildContext context) {
return AppBar(
actions: <Widget>[
Padding(
padding: EdgeInsets.only(right: 35.0),
child: ElevatedButton(
child: Icon(Icons.menu, color: Colors.white),
onPressed: () {
Scaffold(
endDrawer: Drawer(
child: ListView(
padding: EdgeInsets.zero,
children: const <Widget>[
DrawerHeader(
decoration: BoxDecoration(
color: Colors.black,
),
child: Text(
'Menu',
style: TextStyle(
color: Colors.pink,
fontSize: 24,
),
),
),
ListTile(
leading: Icon(Icons.message),
title: Text('Messages'),
),
ListTile(
leading: Icon(Icons.account_circle),
title: Text('Profile'),
),
ListTile(
leading: Icon(Icons.settings),
title: Text('Settings'),
),
],
),
),
);
},
)),
],
backgroundColor: Colors.black,
title: GestureDetector(
onTap: () {
Navigator.of(context).push(
MaterialPageRoute(
builder: (_) => FirstPage(),
),
);
}, // Image tapped
child: Image.asset(
'images/logo.png',
fit: BoxFit.scaleDown,
height: 30,
width: 200,
),
));
}
}
