How to use GetX in Flutter: install, state, routes and tips
Updated · written with AI from the project's own documentation and checked against our catalogue data
GetX is a Dart package for Flutter apps that bundles state management, route navigation and dependency injection in one library. It also offers helpers for showing snackbars, dialogs and bottom sheets without passing a BuildContext. This guide shows you how to add it to a Flutter project and where each of its three main parts fits, so you can decide whether it suits your app.

- 1Check prerequisites. Make sure the Flutter SDK and Dart SDK are installed on your machine.
- 2Add the package. Run flutter pub add get in your Flutter project folder.
- 3Plan your structure. Separate screens, controllers and services, following the README's view, logic and dependency split.
- 4Create a controller. Put state and business logic in a controller class so widgets can read it without knowing its source.
- 5Navigate and inject. Use GetX route navigation and dependency injection so screens do not need BuildContext to reach controllers.
- 6Use helpers and utilities. Add snackbars, dialogs, translations or theme switching where your app needs them.
Install GetX in your Flutter project
GetX is distributed as a package on pub.dev. You need the Flutter SDK and the Dart SDK installed before you start.
Run the install command from the README in your project folder to add the package.
- Prerequisites: Flutter SDK and Dart SDK
- Install method: package manager (pub)
flutter pub add getUnderstand the three pillars: state, routes and dependencies
The README describes GetX as combining three things: state management, route management and dependency management. Each is a separate feature you can use on its own.
GetX says it keeps UI code, business logic and service setup separated. Controllers hold logic, and widgets read from them, so the view does not need to know how the data is produced.
Dependencies are loaded lazily by default, and GetX removes them from memory when they are no longer used unless you declare them with permanent: true.
- State management: reactive state for updating widgets
- Route management: moving between screens without BuildContext
- Dependency management: injecting controllers and services
Navigate between screens and show messages without context
The README states that you do not need context to navigate between routes. GetX also provides helpers for showing snackbars, dialogs and bottom sheets without a BuildContext.
Use these helpers when you want navigation or feedback to be triggered from controller code rather than from inside the widget tree.
- Navigate between routes without passing context
- Show snackbars, dialogs and bottom sheets without context
- Keep presentation logic out of the widget tree
Add translations and theme switching
The source says GetX offers translations and theme switching alongside routing. The README includes sections on translations, locales, system locale and changing the theme.
These features are useful if your app needs more than one language or a light and dark theme, and you want them handled by the same package as routing.
- Translations and locales
- Change locale and use the system locale
- Change theme
Know the trade-offs before you commit
GetX uses its own conventions rather than a widely known pattern such as Provider or BLoC. Developers who prefer minimal, explicit architecture may find it less familiar.
The README stresses that one library covers many concerns. If your project cannot accept a third-party package that couples many features together, consider a smaller tool.
GetX is described as a Flutter solution. The README describes it for Flutter apps, not for other non-Flutter projects.
- Uses its own conventions instead of a standard pattern
- One package covers many concerns
- Designed for Flutter
What people use it for
- Building a first Flutter app with one package for state, routes and dependencies
- Keeping controllers and services in a consistent structure across a team's screens
- Adding multi-language support and light and dark themes alongside navigation
- Showing snackbars or dialogs from controller code without passing context
Frequently asked questions
How do I install GetX in Flutter?
Add the package to your Flutter project with flutter pub add get. You need the Flutter SDK and Dart SDK installed first.
Is GetX free to use?
GetX is released under the MIT licence, according to the repository's details. Check the licence file in the repository for the full terms.
Does GetX work outside Flutter?
The README describes GetX as a Flutter solution, so it is intended for Flutter apps. It is not described for non-Flutter projects.
What are the alternatives to GetX?
Projects compared in this context include Provider, flutter_bloc, Riverpod and GetIt. Provider and BLoC are well-known standard patterns, which may suit developers who prefer explicit architecture.
Is GetX good for beginners?
The README says it is easy for beginners and that it bundles several features into one package, which can mean fewer packages to learn. Developers who want a widely used pattern may prefer something else.
Does GetX remove unused controllers from memory?
By default, the README says resources are removed from memory when they are not used. To keep a dependency in memory, you must declare it with permanent: true.

Our verdict
GetX suits Flutter developers, especially beginners and teams, who want state management, routing, dependency injection, translations and theme switching from one package with a consistent structure. Developers who prefer minimal, explicit architecture or a standard pattern like Provider, BLoC, Riverpod or GetIt, or who cannot accept one library covering many concerns, should choose something else.
