## [4.2.4]
- Fix Get.offAll removing GetxServices from memory
## [4.2.3]
- Fix back button on navigator 2
- Added parameters and arguments to Get.rootDelegate
## [4.2.1]
- Remove [] from docs to try fix pub score
## [4.2.0] - Big update
This update fixes important bugs as well as integrates with Navigator 2. It also adds GetRouterOutlet, similar to angular RouterOutlet thanks to @ahmednfwela. Also, the documentation translation for Vietnamese (@khangahs) has been added, making the GetX documentation available for 11 different languages, which is just fantastic for any opensource project. GetX has achieved more than 5.4k likes from the pub, and more than 4k stars on github, has videos about it with 48k on youtube, and has communities in the 4 hemispheres of the earth, besides having a large list of contributors as you see bellow. We're all happy to facilitate development with dart and flutter, and that making programming hassle-free has been taken around the world.

- Fix: Navigating to the same page with Get.offNamed does not delete the controller from that page using Get.lazyPut.

- **성능:** GetX는 성능과 최소한의 리소스 소비에 중점을 둡니다. GetX는 Streams나 ChangeNotifier를 사용하지 않습니다.
- **생산성:** GetX는 쉽고 친숙한 구문을 사용합니다. 원하시는 것보다 Getx에는 항상 더 쉬운 방법이 있습니다. 개발 시간을 아끼고 애플리케이션을 최대 성능으로 제공할 수 있습니다.
일반적으로 개발자는 메모리에서 컨트롤러들을 제거하는 데 관심을 가져야합니다. GetX에서는 리소스가 기본적으로 사용되지 않으면 메모리에서 제거되므로 필요하지 않습니다. 만약 메모리에 유지하려면 종속성에서 "permanent : true"를 명시적으로 선언해야합니다. 이렇게하면 시간을 절약 할 수있을뿐만 아니라 불필요한 메모리 종속성이 발생할 위험이 줄어 듭니다. 종속성은 기본적으로 lazy로 로드됩니다.
- **조직화:** GetX는 화면, 프레젠테이션 로직, 비즈니스 로직, 종속성 주입 및 네비게이션을 완전히 분리 할 수 있습니다. 라우트간 전환을 하는데에 컨텍스트가 필요하지 않아 위젯 트리(시각객체)에 독립적입니다. inheritedWidget을 통해 컨트롤러/블록에 접근하는 데 컨텍스트가 필요하지 않아 시각화 계층에서 프레젠테이션 로직과 비즈니스 로직을 완전히 분리됩니다. 이 GetX는 자체 종속성 주입 기능을 사용하여 DI를 뷰에서 완전히 분리하기 때문에 다중 Provider를 통해 위젯 트리에서 컨트롤러/모델/블록으로 주입 할 필요가 없습니다.
GetX를 사용하면 기본적으로 클린 코드를 가지게 되어 애플리케이션의 각 기능을 쉽게 찾을 수있습니다. 이것은 유지 보수를 용이하게 하며 모듈의 공유가 가능하고 Flutter에서는 생각할 수 없었던 것들도 전부 가능합니다.
BLoC은 Flutter에서 코드를 구성하기 위한 시작점으로 비즈니스 로직과 시각객체를 분리합니다. Getx는 비즈니스 로직 뿐만 아니라 프레젠테이션 로직을 분리하는 자연스러운 진화입니다. 추가로 종속성 주입과 라우트 또한 분리되고 데이터 계층이 모두로부터 분리됩니다. Hello World를 구현하는 것보다 더 쉽게 모든 것이 어디 있는지 알수 있습니다.
Flutter SDK와 함께 GetX를 사용하면 가장 쉽고 실용적이며 확장 가능한 고성능 어플리케이션을 만들수 있습니다. 초보자에게는 쉬우며 전문가에게는 정확하고 완벽하게 동작하는 대규모 생태계가 함께합니다. 안전하고 안정적이며 업데이트되고 기본 Flutter SDK에 없는 광범위한 API 빌드를 제공합니다.

Extend this widget to build responsive view.

information about the screen size and type.
##### 사용 방법
You have two options to build it.
- with `builder` method you return the widget to build.
- with methods `desktop`, `tablet`,`phone`, `watch`. the specific
method will be built when the screen type matches the method
when the screen is [ScreenType.Tablet] the `tablet` method
will be exuded and so on.
**Note:** If you use this method please set the property `alwaysUseBuilder` to `false`
With `settings` property you can set the width limit for the screen types.
