Creating a Flutter Web application and building a Blackbox test automation
Flutter is a powerful UI toolkit that allows you to build natively compiled mobile, web, and desktop applications from a single codebase. In this article, we’ll create a simple Flutter app that demonstrates basic state management by implementing increment and decrement functionalities for a counter.
Step-by-Step Guide
Step 1: Setting Up the Flutter Environment
Before we begin, ensure that you have Flutter installed on your machine. If not, you can follow the [official Flutter installation guide](https://flutter.dev/docs/get-started/install).

Open your terminal and run the following command to create a new Flutter project:
flutter create counter_app
Navigate into your project directory:
cd counter_app
Step 3: Writing the Flutter Code

import 'package:flutter/material.dart';
import 'package:flutter/rendering.dart';
void main() {
runApp(const MyApp());
RendererBinding.instance.ensureSemantics();
}
class MyApp extends StatelessWidget {
