How can I add an admin page to the existing pages? I just want one default admin to enter which will only display users from Firebase. I would like a specific email and password to be given which will allow access for that one admin.
I’m attaching the login page

class MyLogin extends StatefulWidget {
const MyLogin({Key? key}) : super(key: key);
@override
State<MyLogin> createState() => _MyLoginState();
}
class _MyLoginState extends State<MyLogin> {
//editing controller
final TextEditingController emailController = TextEditingController();
final TextEditingController passwordController = TextEditingController();
int _success = 1 ;
late String _userEmail = "";
final user = FirebaseAuth.instance.currentUser;
Future SignIn() async {
await FirebaseAuth.instance.signInWithEmailAndPassword(
email: emailController.text.trim(),
password: passwordController.text.trim()
);
}
@override
Widget build(BuildContext context) {
return Container(
decoration: const BoxDecoration(
