Do you have experience in developing and executing integration tests for applications?

Yes, I have experience developing and executing integration tests in Flutter applications. Integration tests allow testing the interaction of multiple components of the application and its operation on a real device or emulator.

For this, I used the integration_test package, which enables writing tests that simulate user actions and verify the correctness of UI and business logic.

Here's a simple example of an integration test:

import 'package:integration_test/integration_test.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:my_app/main.dart' as app;

void main() {
  IntegrationTestWidgetsFlutterBinding.ensureInitialized();

  testWidgets('Check main screen loading', (WidgetTester tester) async {
    app.main();
    await tester.pumpAndSettle();

    expect(find.text('Welcome'), findsOneWidget);
  });
}

This approach helps identify errors that are not visible during unit testing.
