Firebase dataSnapshot.value is now Object? It was Map

Help. My flutter class works perfectly last year, but now, DataSnapShot value property returns Object? as oppose to Map.

import 'package:firebase_database/firebase_database.dart';

class Users {
  String id;
  String email;
  String name;
      
  Users({
    required this.id,
    required this.email,
    required this.name,
  });

  factory Users.fromSnapshot(DataSnapshot dataSnapshot) => Users(
        id: dataSnapshot.key!,
        email: dataSnapshot.value["email"],
        name: dataSnapshot.value["name"],
      );
}

I want to read data from my firebase realtime database referenced, any help will be fine.
