As a Flutter developer, you know that state management is a crucial part of building a performant and maintainable app. With so many state management libraries available, choosing the right one can be a challenge. Enter GetX – a lightweight and powerful state management solution that’s gaining popularity among Flutter developers.
So what is GetX? At its core, GetX is a state management library that provides quick, stable, and light management of application states. It’s designed to consume minimum resources and provide better performance compared to other state management libraries, such as MobX, BLoC, Redux, Provider, and more. GetX also offers a powerful micro-framework that allows developers to manage states, make routing, and perform dependency injection with ease.
One of the standout features of GetX is its three key principles: performance, productivity, and organization. By prioritizing these principles, GetX offers several advantages over other state management solutions.
First and foremost, GetX is designed for high performance. It utilizes low-latency GetValue and GetStream to improve performance, ensuring that your app runs smoothly even with complex state management.
Secondly, GetX is incredibly productive. Its syntax is easy to use, saving developers time and increasing the speed of the app. GetX only uses the resources that are currently needed and frees them automatically when they’re no longer necessary, further improving productivity.
Finally, GetX offers excellent code organization. It organizes code into View, Logic, navigation, and dependency injection, making it easy to navigate between screens without the need for context. GetX separates business logic and presentation layers for easy organization.
In terms of its capabilities, GetX provides several useful features for Flutter developers. For example, it offers two types of state management: Simple State Manager using GetBuilder and Reactive State Manager using GetX and Obx. With GetX, you can also build widgets like Snackbar, Bottomsheets, and dialogs without using context. And if you need to fetch data from other classes, you can do so in a single line of code with GetX using Get.put().
So why should you choose GetX for your next Flutter project? Simply put, it’s a lightweight and powerful state management solution that can improve app performance and increase productivity. GetX’s easy-to-use syntax, code organization, and lack of boilerplate code must-have for any Flutter project. Whether you’re building a simple app or a complex one, GetX is worth considering. Give it a try and see the difference for yourself!
Here’s how you can implement GetX:
Implementation:
Step 1: Add the dependencies
Add dependencies to pubspec — yaml file.
dependencies:
flutter:
sdk: flutter
get: ^4.6.1
Step 2: Import
import ‘package:get/get.dart’;
How to implement code in dart file :
import ‘package:flutter/material.dart’;
import ‘package:flutter_getx_statemanagement/splash_screen.dart’;
import ‘package:get/get.dart’;
void main() => runApp(const MyApp());
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
@override
Widget build(BuildContext context) {
return GetMaterialApp(
title: ‘Flutter GetX State Management Demo’,
theme: ThemeData(
primarySwatch: Colors.red,
),
home: const Splash(),
debugShowCheckedModeBanner: false,
);
}
}
Create a new dart file called home_page_controller.dart inside the lib folder.
import ‘package:get/get.dart’;
class HomePageController extends GetxController {
final count = 0.obs;
increment() => count.value++;
}
Create a new dart file called home_page.dart inside the lib folder.
final HomePageController controller = Get.put(HomePageController());
Obx(
() => Text(
‘${controller.count.value}’,
style: Theme.of(context).textTheme.headline4,
),
),
We will add floatingActionButton, we will call the increment method when the floatingActionButton is pressed.
floatingActionButton: FloatingActionButton(
onPressed: controller.increment,
tooltip: ‘Increment’,
backgroundColor: Colors.cyan,
child: const Icon(Icons.add),
),
