GetX for Flutter

Introduction

Whenever we start creating any application in Flutter, we must determine which state management we must use. It would be more comfortable for you to make this decision through this blog. Here, in this tutorial: Flutter state management using GetX: I would like to present GetX, a powerful Flutter framework.

What is GetX?

GetX is not just a state management library; it is an ultra-light, fast, and dependable microframework for Flutter that supplies route management and dependency injection as well.

Flutter is progressing very quickly and gaining a favourite place among innovators. As a developer, we must cope with regular Flutter updates, plugins, and other dependencies. Sometimes, it becomes a nightmare to handle such dependencies. GetX solved this issue; it is all in one package, which makes our job quite relaxing. Also, by using GetX, we can bypass the use of StatefulWidget, which lowers the RAM consumption as well.

Why GetX?

So, let's tackle a little more in-depth why we must use GetX to control the condition in the Flutter app. GetX enhances the Flutter application in three different ways:

  • Productivity: Using simple syntax, developers can easily execute GetX state control in Flutter: No matter how complicated a code snippet can be, you can save time with GetX Flutter. It improves productivity by reducing development time and delivering maximum performance.
  • Organization and readability: GetX decouples the idea. It delivers easy and uncomplicated syntax, consequently improving the readability and format of the company logic.
  • Performance: As mentioned above, GetX concentrates on how the fewest resources can be consumed, which can assist in improving the application's version. It doesn't use ChangeNotifier or streams. Look at the below RAM chart showing different state managers.

Features of GetX

State management
  • Executing reactive programming is a very complicated task, but with GetX, it is quite simple:
  • There is no need to build StreamController.
  • It is not necessary to create Stream Builder.
  • There is no need to build a class for each state.
  • There is no need to set an initial value.
  • Then what must be done?

Make the variable observable as shown below:

GetX for Flutter

var name = 'Foo'.obs;

Obx(() => Text("${controller.name}"));

That's it; you are done. All devices will be updated wherever the variable has been used.

Route management

You can efficiently navigate to any screen using GetX with little to no code.Surprise??

It just requires following some essential steps:

Add "Get" before your app name.

GetMyApp (before: MaterialApp) ( home: MyHome(), )

To navigate to a new screen, just

Get.to(NextScreen());

There are numerous other possibilities, like going back, going to a specific page, and many more.

Dependency management

GetX provides a very simple and straightforward method for adding dependencies without the need for context.Assume we go to a specific page via multiple routes; we can get the deal in our controller using only the find() method.

Localization

Providing support for numerous languages is straightforward with GetX. By following the simple measures below, you can execute translation in your Flutter app.

Make a custom class, extend it with translation, and add text for needed language support.

Translations are extended by class messages.

@override Map > get keys => { 'en_US': { 'the surname': 'Surname', }, 'de_DE': { 'surname': 'Familien - oder Nachname', } }; } Simply append.tr to the key that you want to translate. Text('surname'.tr); You can even pass the argument to the text.

Storage

GetX delivers extra lightweight key-pair value by remembering storage capabilities. Hence, we can get persistent data throughout the application if required.

Theme

Theme creation with GetX becomes easier compared to anything else. Simply create a custom theme and pass it through the GET. Change the theme () function without any boilerplate and you're done.

Get.changeTheme(ThemeData.light());

Responsive view

Delivering support for numerous devices is sometimes very complex. GetX provides the ability to quickly create applications that support multiple dimensions, such as desktop, tablet, mobile, and so on.
