Introduction to State Management and Navigation

We often experience certain changes as we move from one point to another. These changes can affect the state of various aspects of our lives, such as personal development or relationships. This is also true for the development of a software project.

Let’s assume we have a Flutter app with a button that, when pressed, causes a bulb to turn on or off. To implement this behavior, we would need to set up an event listener for the button press and then define the action that should be taken when the event occurs. This could involve updating the state of the bulb, displaying a message to the user, or performing some other task.

What is the GetX framework?

In Flutter, because the design of the UI is declarative, developers can describe how a widget should look in a particular state only once. However, in complex apps that involve data sharing between widgets, it can be challenging to manage the state of each widget individually.

To overcome this challenge, developers can use a state management library like GetX, which provides a lightweight and robust solution for building applications with Flutter. GetX includes routing management and dependency injection features, making it a mini-framework that can help developers build apps more efficiently.

Setting up

We can add packages to our Flutter project by simply adding the following lines in the dependencies section of the pubspec.yaml file:

Finally, we run the flutter pub get command in the terminal to import and install the Get package in the current file.

The GetX ecosystem focuses on three critical sections of Flutter development. Let’s discuss these sections. ...
