Flutter file_picker with Riverpod

I'm trying to learn Riverpod nowadays and I'm trying to use the file_picker package with it. Can't find a way to implement it in this code. I created two state notifiers that are supposed to hold values of the path and the isUserAborted values. In the example of the file_picker package they used setState with statefulWidget on the selectFolder method, but I'm wanting to use ConsumerWidget instead. How can I manage to do this? Have a good day!

import 'package:file_picker/file_picker.dart';
import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:hooks_riverpod/hooks_riverpod.dart';

class DirectoryPathNotifier extends StateNotifier<String?> {
  DirectoryPathNotifier() : super("NoPathSelectedYet");
}

class UserAbortedNotifier extends StateNotifier<bool> {
  UserAbortedNotifier() : super(false);
}

final directoryPathProvider =
    StateNotifierProvider<DirectoryPathNotifier, String?>((ref) {
  return DirectoryPathNotifier();
});

final userAbortedProvider =
    StateNotifierProvider<UserAbortedNotifier, bool>((ref) {
  return UserAbortedNotifier();
});

class CreamPath extends ConsumerWidget {
  CreamPath({super.key});

  List<PlatformFile>? _paths; //used
  String? directoryPath; //Used
  bool isLoading = false; //used
  bool userAborted = false; //Used

  Future<void> _selectFolder() async {
    String? path = await FilePicker.platform.getDirectoryPath();
    setState(() {
      directoryPath = path;
      userAborted = path == null;
    });
  }

  @override
  Widget build(BuildContext context, WidgetRef ref) {

return Scaffold(
  appBar: AppBar(
    title: const Text('File Picker example app'),
  ),
  body: Center(
    child: Padding(

                                      final path = kIsWeb
                                          ? null

                                              .map((e) => e.path)
                                              .toList()[index]
                                              .toString();

                                      return ListTile(
                                        title: Text(
                                          name,
                                        ),
                                        subtitle: Text(path ?? ''),
                                      );
                                    },
                                    separatorBuilder:
                                        (BuildContext context, int index) =>
                                            const Divider(),
                                  )),
                                )
                              : const SizedBox(),
            ),
          ],
        ),
      ),
    ),
  ),
  );
    }
 }

I write this code inside the build method:

final directoryPath = ref.watch(directoryPathProvider);
final userAborted = ref.watch(userAbortedProvider);

Future<void> selectFolder() async {
  String? path = await FilePicker.platform.getDirectoryPath();
  ref.read(directoryPathProvider.notifier).state = path;
  ref.read(userAbortedProvider.notifier).state = path == null;
}

It's OK now.
