4 Learn How to Use the setState Function in Flutter | Flutter Tutorial | Delite Coder

Welcome to another Flutter tutorial! In this video, we will explore the setState function in Flutter and learn how to use it effectively in your Flutter applications.

The setState function is an extremely important part of Flutter development as it allows you to update the user interface based on changes in data. By calling setState, you can trigger a rebuild of the UI, ensuring that any changes made to your data are reflected properly.

In this tutorial, we will start by creating a simple Flutter application. We will add an AppBar with the title "Set State" to our app. Inside the body of the app, we will use a Column widget and add a Text widget. We will also define a variable named sample and use it to display dynamic content in the app.

Next, we will add a Floating Action Button (FAB) using the FloatingActionButton widget. When the FAB is pressed, we will increment the value of the sample variable using the setState function. This will trigger a rebuild of the UI and display the updated value.

By the end of this tutorial, you will have a clear understanding of how to use the setState function in Flutter. Don't forget to subscribe to my channel for more Flutter tutorials and hit the like button if you found this video helpful!
