![]() ![]() ![]() It supports the decoupling of the user interface, presentation logic, business logic, dependency injection, and navigation. GetX helps developers realize a high level of productivity through easy and pleasant syntax without sacrificing app performance. ![]() The major pillars of the GetX package are high-performance state management, intelligent dependency injection, and route management. GetX is a simple yet powerful Flutter package. Integrating the GetX ecosystem What is GetX? This will generate the default Flutter counter project in the main.dart file. Leave the default Android and iOS languages to Kotlin and Swift respectively.Choose a directory where you want the project to be saved.Since we are building an online shop, we can name the project as shopping_getx.Next, fill in the following project details to set up the project completely: Ensure that you set the type as Flutter application.īe sure you selected the path where your Flutter SDK is located then click next. To get started, launch Android studio and create a new Flutter project. In this project, we will be using Android Studio. Some basic knowledge of Dart and Flutter.Ĭreating a Flutter application in Android Studio.Reusable component of the GetX ecosystem.How to use the GetBuilder sub-ecosystem to manage state.Explore the Getx navigation capabilities.Using Obx to maximize the power of reactive programming.How to use GetX as a state management tool.How to setup Flutter project and configure dependencies.With this app, we will demonstrate the power of the GetX package. In this tutorial, we will build a shopping mobile application that allows users to view products, like items, add a product to a cart, as well as place orders.Īfter placing orders successfully, users can still access other products. This article teaches you how to use the GetX state management package to solve state management problems in Flutter. Though this feature is useful, it causes data to be passed to widgets that don’t need it.Īnother disadvantage is that the business logic is tightly coupled to the user interface. Stateful widgets pass data through the constructors of child widgets. However, this is quite difficult to implement in a complex application. When the state of your application changes, the system rebuilds the user interface.įlutter traditionally uses the Stateful Widget to manage the state. We can access all the other components and widgets provided by the Flutter SDK with the following: import 'package:flutter/material.State management enables you to pass data from one user interface to another. Flutter’s MaterialApp class is a predefined class in a Flutter app. Next, we need to create a default MaterialApp. This command creates the files, folders, and everything needed to start a new Flutter project. The first step is to create a new project: flutter create card_widget This can help establish your knowledge of Flutter widgets and also help you see the various techniques you can apply to create a single widget from the combination of others. In this tutorial, we will be building a card widget that functions as a business card with an image, job description, and company name. For example, the built-in card widget in Flutter does not fully handle our needs, so we have to join it with other widgets to build our own reusable and fully customizable card widget. However, there are times when some built-in Widgets do not satisfy an immediate need in an app, and you need to combine one or two. Combining these ready-made widgets makes development easier and faster. Its properties can be updated, changed, or deleted while it is still in runtimeĮxamples of widgets are the center widget (aligns its child or item to the center), row widget (aligns its children in a horizontal format), and column widget (aligns its children vertically). Stateful widgets are widgets whose information and properties can change during the run time of the widget.Whatever information they carry remains constant throughout the lifetime of the widget Stateless widgets are widgets that are immutable, meaning they do not change.Widgets form the basis of views and screens in a Flutter app, and appropriately combining the diverse widgets available will give you a beautifully designed screen. No matter how complex or large a Flutter app is, they all use the basic building blocks referred to as “widgets”. Widgets in Flutterīuilding fully functional apps with Flutter can be exciting, because it involves bringing together various components and combining them one at a time to build a complete app. At the end of this article, you will have a reusable card widget to customize as much as you want. In this article, you will learn all about widgets and the card class in Flutter, while bringing both together to create a card widget.
