here is my code,

class ProfileOthers extends StatefulWidget {
  const ProfileOthers({super.key, required this.data});

  final Map<String, dynamic> data; //I am hoping to make use of this data

  @override
  State<ProfileOthers> createState() => _ProfileOthersState();
}

Want to pass arguments in stateless widget from another screen, I’m new in flutter.

one simple way to access variables passed through initializing that widget within the build method would be using

    widget.data

where you want like displaying it within a string.

Using the code you provided you could write something like this:

class ProfileOthers extends StatefulWidget {
    const ProfileOthers({super.key, required this.data});

    final Map<String, dynamic> data; 

    @override
    State<ProfileOthers> createState() => _ProfileOthersState();
}

class _ProfileOthersState extends State<ProfileOthers> {
   @override
   Widget build(BuildContext context) { 
       return Scaffold(
           body: Container(
              child: Text(
                 '${widget.data['Sample key value']}'
              ),
           ),
       );
   }
}

```
class UserProfileScreen extends StatefulWidget {
   final Map<String, dynamic> userData;
   const UserProfileScreen ({super.key, required this.userData});

  @override
  State<UserProfileScreen> createState() => _UserProfileScreenState();
}
```
you can access this parameter as shown below,
```
Text(widget.userData['name']),
```
