Overview

This comprehensive course walks the reader through each feature of the GetX package while explaining the relevant concepts along the way. After completing this course, the reader will thoroughly understand the GetX ecosystem and can confidently use the package in their Flutter apps. Look at the course outline and briefly discuss each chapter’s learning outcomes.

Course outline

The course is segmented into the various aspects of app development that the GetX package helps us with. Each chapter covers one aspect, and the accompanying lessons further break it into smaller topics. Let’s go through each one by one.

State management

State management is one of the hottest topics in the Flutter community. In this chapter, we learn about the various approaches GetX provides to managing an app’s state. We will cover the differences between the approaches, the relevant use cases for each, and, ultimately, which is best in a certain scenario.

Dependency injection

Dependency injection is a technique for efficiently structuring and organizing code. This chapter highlights the flexible ways to inject and manage dependencies in the GetX ecosystem. It covers bindings, lazy loading, and wrapper widgets like GetView and GetWidget.

Route management

Route management in Flutter is quite simple for most use cases. However, advanced use cases like data transfer between pages, dynamic URLs for the web, and nested navigation can be tricky to implement. This chapter covers route management using GetX, from beginner to advanced.

Adaptive UI and responsiveness

This chapter discusses the various utilities provided by GetX to effortlessly achieve responsiveness. We’ll learn about the GetResponsiveView widget, which enables us to render different layouts based on different screen sizes.

Networking with GetConnect

GetConnect is a powerful tool for making HTTP requests over REST and GraphQL protocols. It also features persistent communication using WebSockets. This chapter covers GetConnect, its configuration options, and advanced features like interceptors, timeouts, and more.

Utilities

GetX offers a collection of utilities that help with localization, theming, etc. In addition, there are extensions to help with miscellaneous tasks such as getting screen information. This chapter documents all these utilities with examples.

Local storage with GetStorage

GetStorage is a simple, easy-to-use synchronous local storage solution. It is an excellent alternative to shared preferences. In this chapter, we’ll learn how to implement local storage services organizationally.

Project structure

The GetX ecosystem recommends two kinds of project structures: getx_pattern and clean. Although they take different approaches, both are ultimately designed to organize our codebase in a scalable and maintainable manner.

Automation with Get CLI

Get CLI is a command-line utility that can significantly improve our development process by automating specific tasks. For example, we get commands that help create pages and models, install dependencies, and generate the entire project structure. We will discuss some of its commands and the two kinds of project structures it supports.

GetX code snippets

GetX Snippets is an IDE extension available for VS Code and IntelliJ. It offers a ton of snippets that generate everything from getters/setters to controllers to entire widgets. The chapter is a quick walkthrough of the most helpful snippets.
