Flutter SDK is an excellent tool for developing cross-platform applications from a single codebase. So, it's no surprise that many professionals and learners have decided to gain mastery over Flutter concepts.

One such concept is state management, and many, despite having intermediate-to-advanced proficiency in Flutter, still struggle with this concept. This course will help you learn and master the best practices for state management in Flutter.

You will learn to use the two best Flutter libraries, Riverpod and Provider, for state management. You will even learn about reducing widget rebuilds by managing their state.

Master State Management in Flutter

# What is the `onPressed` method

The Flutter framework helps us to build beautiful design patterns. If you have already learned Flutter a little bit, then you may have learned that you cannot drag and drop interfaces. Instead, you need to write the necessary code.



However, since the coding part involves only the Dart programming language, it becomes easier for us. Given that we must have a basic Dart programming concept for this section of the course.

Any User Interface needs interaction from the user. The Flutter app should allow users to interact with itself, no matter how we design that app.


As long as we think of UI and interaction, we can think of the behaviour of a simple button. If we press that button, it should call a method in our widget class.

For example, think about the `ElevatedButton` widget that uses a callback through the `onPressed` method.

In this article, we will understand this fundamental concept of `onPressed` in Flutter.

# How to use the `onPressed` method?

To understand the `onPressed` method, we need to use it inside a Flutter app first. 

The following image represents a button app, which we will build step by step:



Learn what the "onPressed" method is and how you can use it efficiently with callbacks and functions.
