Do you have experience writing unit tests in projects?

Yes, in Flutter projects I regularly wrote unit tests to verify the logic of widgets, services, and business logic. I used the flutter_test package and mockito for creating mocks.

Here's an example of a simple widget test:

import 'package:flutter_test/flutter_test.dart';
import 'package:flutter/material.dart';

void main() {
  testWidgets('Text display check', (WidgetTester tester) async {
    await tester.pumpWidget(MaterialApp(
      home: Scaffold(
        body: Text('Hello, test!'),
      ),
    ));

    expect(find.text('Hello, test!'), findsOneWidget);
  });
}

This approach helps quickly identify errors and maintain code quality.
