The GetX microframework is an effective way to manage your state and navigate through your application. It helps you to keep your code clean and simple. This guide will teach you how to use GetX with Flutter. Read more here.
GetX is a new way of managing state for React apps. It focuses on simplicity, flexibility, and ease of use. This blog will cover what GetX is, why it was built, and how it relates to other state management libraries.
State management is an important part of Flutter, and understanding how it works can make your development experience a lot smoother. In this article, we will provide you with everything you need to know about state management in Flutter. We’ll explain what states are and give an overview of the different ways that you can use them. We’ll also cover the basics of transitions, animations, and propagation. By the end of this guide, you will have a good understanding of how state management works in Flutter and be able to apply it to your own projects without any problems!
1. What is the use of GetX?
GetX is a state management library. It is not only a state management library, but instead, it is a microframework combined with route management and dependency injection. The idea of GetX is to make the developing process easier and more efficient. Something that is especially useful in the beginning of the project, where you are still trying to figure out how to get started. With GetX, you automatically have a working application and all the tools to work with it. There is no need to think about which tools to use, because everything is already there.
2. what is The three pillars in GetX?
State management is a key topic in every application and often the topic of many discussions. Sometimes it feels like there are a million ways to create, handle, and manage state. We created GetX to solve a problem, and state management was a key factor. We believe that there are three things that you need to know when it comes to state management. They are:
- 1. State should be persistent
- 2. State should be testable
- 3. State should be easy to use
3. GetX's core functionality
The GetX library is based on the idea of Getters and Setters. Setters are used to store data, and Getters are used to retrieve data. Setters are declared with GetBuilder and Getx, and Getters are declared with Obx. For example, let's say we wanted to declare a person and their name. We would create a new setter with "person" and "name" as arguments, and then assign the setter to a new person. We can then retrieve the person's name by accessing the getter.
4. Understanding state in GetX
State is one of the key concepts in GetX. It is similar to the concept of state in other frameworks like React or Vue, but different in its implementation. State is the data that represents a particular state of the application. To make this data available everywhere in an application, GetX uses an instance of a StateProvider and injects it everywhere through the dependency injection.
managing the GetX state
I'll take it step by step, as I usually do, and make an effort to be as descriptive and thorough as I can in my explanation of the procedure.
Make a fresh application
In your preferred IDE, start a new application. To start, delete all starter comments by choosing the find and replace option from the Edit menu, then entering the characters /.*. When you click the delete button, Flutter's comments in the starter code will be selected.
Include necessary dependencies
Your pubspec.yaml file should contain the following dependencies.
You can take a test by clicking here.
A new version of the MaterialApp widget
The first step after adding the dependencies is to change the MaterialApp widget in your main. dart file to GetMaterialApp. All GetX properties throughout the application are accessible using this.
Integrate GetX Controller
We already know that GetX separates the user interface from the business logic. GetX Controller is useful in this situation.
In your application, you can always create more than one controller. When you wrap a specific widget with its Observer, the GetX Controller class regulates the state of the UI so that it only rebuilds when the state of that specific widget changes.
Our controller class, StoreController, which extends GetxController, is being added as a new Dart file:
However, when using GetX, we must add obs to the end of the value to make the variables observable.Other components of the application that depend on the variable will then be informed when it changes.Our initialized value will now appear as follows:
Then, we develop three procedures for changing the name, gaining more followers, and altering the status of the store.
Conclusion
Conclusion: State management in front-end applications is required. However, there are a ton of state management libraries out there already. GetX wants to take on the problem of integration and make a library that stands out from the pack.
