I’am tryng to run my unit test for this project, and it’s giving me this error message:

MissingPluginException(No implementation found for method getApplicationDocumentsDirectory on channel plugins.flutter.io/path_provider)
package:flutter/src/services/platform_channel.dart 332:7  MethodChannel._invokeMethod
LateInitializationError: Field 'todoBox' has not been initialized.
testunit_testtodo_unit_test.dart        todoBox
testunit_testtodo_unit_test.dart 35:13  main.<fn>

How can I solve this error?

**
Here is the code:
**

import 'dart:io';

import 'package:flutter/widgets.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:hive/hive.dart';
import 'package:mocktail/mocktail.dart';
import 'package:path_provider/path_provider.dart';
import 'package:todo_app/src/modules/adapter/todo_adapter.dart';

late TodoItemMock todoItemMock;
late Box<TodoItemMock> todoBox;

class TodoItemMock extends Mock implements TodoItem {}


class HiveConfig {
  static start() async {
    Directory dir = await getApplicationDocumentsDirectory();
    Hive.init(dir.path);
  }
}

void main() {
  WidgetsFlutterBinding.ensureInitialized();
  setUp(
    () async {
      await HiveConfig.start();
      Hive.registerAdapter(TodoItemAdapter());
      todoBox = await Hive.openBox<TodoItemMock>('todoBox');
    },
  );

  tearDownAll(
    () async {
      await todoBox.close();
    },
  );

  test('Get no results from the Box', () async {
    expect(todoBox.get(0), completion(findsNothing));
  });
}

I tried to make a Mock for the path provider but it’s not possible to call the class to mock it
