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


We will discuss two things in this lesson. First, we will learn what a callback is. 

Then, we'll explore how to pass a function in Flutter.

In addition to these questions, we’ll also try to understand callback.

In computer programming, we pass functions as arguments to other code. Functions that're passed as arguments are called callbacks.

Other code in the application can call back or execute the argument when it is needed.

Let’s see how callbacks work in Flutter.

In a stateful widget, consider a function like this:
