About this course

GetX is a library that serves as an all-in-one solution to state management, dependency injection, route management, and networking in our apps. It also has several utilities to achieve responsiveness, localization, theming, and more. Furthermore, the package is complemented by other tools in the GetX suite that enable local storage, code completion, and automation. These packages and tools seamlessly integrate to form something we call the GetX ecosystem.

This course is a comprehensive guide to the GetX ecosystem. We will explore every package feature and understand the corresponding concepts thoroughly. In addition to the detailed explanation, every lesson in this hands-on course provides an executable mini-project.

After finishing this course, the reader can confidently use the GetX package to handle their app’s state, organize dependencies, manage the routes, make network calls, tweak themes, add persistent storage, and more. Ultimately, this course enables readers to make their apps more robust and codebase more organized.

What will you learn?

The key takeaways from the course are as follows:

  1. State management: Learn to manage your app’s state in multiple ways through the different approaches offered by GetX.

  2. Dependency injection: Dependency injection is the technique of inserting one class’s variables into another class. Learn how to inject and effectively manage dependencies under the GetX ecosystem.

  3. Route management: Starting from the simpler ones, uncover advanced use cases of route management, such as dynamic URLs and nested navigation. Understand how to deal with such cases in great detail.

  4. Responsiveness: Learn to create responsive layouts so your app looks good on every screen.

  5. Networking: Explore GetConnect, GetX’s internal networking library that makes HTTP requests over both REST and GraphQL protocols. In addition, learn to make persistent connections to the server over WebSockets.

  6. Utilities: Walk through all the GetX utilities that unlock theming, localization, testing, and reactive programming.

  7. Local storage: Learn to implement local storage that persists across app life cycles. It’s a simple key-value storage solution and not a dedicated database.

  8. Project structure: Learn to structure your projects in a scalable and maintainable manner.

  9. Automation: Explore Get CLI, a command-line tool for automating certain tasks, such as project and page creation. Review all its commands.

  10. Code completion: Code snippets provided by GetX Snippets can help improve developer efficiency by many folds. See the usage of the most useful snippets.

Intended audience

Press + to interact

The target audience for this course fits in one of these two categories:

  1. A novice Flutter developer who wants to learn the concepts of state management, dependency injection, route management and networking through an easy-to-learn package. GetX is one of the easiest libraries to get started with because of high levels of abstraction and simplified syntax. And considering the number of features it boasts, the learner can advance their skills within the GetX ecosystem without feeling restricted.

  2. An experienced Flutter developer who wants a solution to develop robust applications in a fast and reliable way. GetX offers multiple approaches to manage the app’s state, dependencies, and routes. This assures that no matter the use case, we can rely on the package to get the job done. The library’s simplicity lets us bootstrap the application in no time; and its wide range of features help us achieve scalability and robustness.

Prerequisites

The course expects the reader to have basic knowledge of Flutter. They should know how to build layouts with Flutter’s widgets, how to navigate between pages and basic networking concepts. We recommend having experience in state management and dependency injection to get the most out of this course, but don’t worry if these concepts sound unfamiliar. We will introduce these concepts at the beginning of their corresponding chapters.
