Mastering StatefulWidget in Flutter: Build a Counter App Tutorial by Junayed Bin Karim

Are you ready to make your Flutter apps interactive? In this tutorial, we dive deep into the fundamental concept of StatefulWidget. Unlike static screens, a StatefulWidget allows your app to change and update its UI dynamically based on user interaction.

We will build a classic Counter App from scratch, where you’ll learn how to manage data and refresh the screen in real-time.

What you will learn in this video:
✅ Setting up a clean Flutter project.
✅ The difference between the Widget and State classes.
✅ How to use setState() to update the UI.
✅ Designing a professional UI with Scaffold, AppBar, and FloatingActionButton.

This is a must-watch for beginners looking to master state management in Flutter!
