Get State Manager is a light, modern and powerful state manager to Flutter

Classes

DisposableInterface
FastList<T>
FullLifeCycleController
GetBuilder<T extends GetxController>
GetBuilderState<T extends GetxController>
GetInterface
GetInterface allows any auxiliary package to be merged into the "Get" class through extensions
GetNotifier<T>
GetResponsiveView<T>
Extend this widget to build responsive view. this widget contains the screen property that have all information about the screen size and type. You have two options to build it. 1- with builder method you return the widget to build. 2- 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.
GetResponsiveWidget<T extends GetLifeCycleBase?>
GetStream<T>
GetStream is the lightest and most performative way of working with events at Dart. You sintaxe is like StreamController, but it works with simple callbacks. In this way, every event calls only one function. There is no buffering, to very low memory consumption. event add will add a object to stream. addError will add a error to stream. listen is a very light StreamSubscription interface. Is possible take the last value with value property.

GetView<T>
GetView is a great way of quickly access your Controller without having to call Get.find [...]
GetWidget<S extends GetLifeCycleBase?>
GetWidget is a great way of quickly access your individual Controller without having to call Get.find
GetX<T extends DisposableInterface>
GetxController
GetxService
Unlike GetxController, which serves to control events on each of its pages, GetxService is not automatically disposed (nor can be removed with Get.delete()). It is ideal for situations where, once started, that service will remain in memory, such as Auth control for example. Only way to remove it is Get.reset().
GetXState<T extends DisposableInterface>
LightSubscription<T>
MiniStream<T>
MiniSubscription<T>
MixinBuilder<T extends GetxController>
Node<T>
Obx
The simplest reactive widget in GetX. [...]
ObxValue<T extends RxInterface>
Similar to Obx, but manages a local state. Pass the initial data in constructor. Useful for simple local states, like toggles, visibility, themes, button states, etc. Sample: ObxValue((data) => Switch( value: data.value, onChanged: (flag) => data.value = flag, ), false.obs, ),
ObxWidget
The ObxWidget is the base for all GetX reactive widgets [...]
ResponsiveScreen
ResponsiveScreenSettings
Rx<T>
Foundation class used for custom Types outside the common native Dart types. For example, any custom "Model" class, like User().obs will use Rx as wrapper.
RxBool
RxController
RxDouble
RxInt
RxInterface<T>
This class is the foundation for all reactive (Rx) classes that makes Get so powerful. This interface is the contract that _RxImpl]
RxList<E>
Create a list similar to List<T>
RxMap<K, V>
Rxn<T>
RxnBool
RxnDouble
RxnInt
RxnNum
RxNotifier<T>
RxnString
Rx class for String Type.
RxNum
RxSet<E>
RxStatus
RxString
Rx class for String Type.
SimpleBuilder
SuperController<T>
Value<T>
ValueBuilder<T>
Manages a local state like ObxValue, but uses a callback instead of a Rx value. [...]

GetStateUpdaterMixin<T extends StatefulWidget>
Complies with GetStateUpdater [...]
NotifyManager<T>
RxObjectMixin<T>
global object that registers against GetX and Obx, and allows the reactivity of those Widgets and Rx values.
ScrollMixin
SingleGetTickerProviderMixin
Used like SingleTickerProviderMixin but only with Get Controllers. Simplifies AnimationController creation inside GetxController. [...]

Functions

debounce<T>(RxInterface<T> listener, WorkerCallback<T> callback, {Duration? time, Function? onError, void onDone()?, bool? cancelOnError}) Worker
debounce is similar to interval, but sends the last value. Useful for Anti DDos, every time the user stops typing for 1 second, for instance. When listener emits the last "value", when time hits, it calls callback with the last "value" emitted. [...]
defaultLogWriterCallback(String value, {bool isError = false}) → void
default logger from GetX
ever<T>(RxInterface<T> listener, WorkerCallback<T> callback, {dynamic condition = true, Function? onError, void onDone()?, bool? cancelOnError}) Worker
Called every time listener changes. As long as the condition returns true. [...]
everAll(List<RxInterface> listeners, WorkerCallback callback, {dynamic condition = true, Function? onError, void onDone()?, bool? cancelOnError}) Worker
Similar to ever, but takes a list of listeners, the condition for the callback is common to all listeners, and the callback is executed to each one of them. The Worker is common to all, so worker.dispose() will cancel all streams.
interval<T>(RxInterface<T> listener, WorkerCallback<T> callback, {Duration time = const Duration(seconds: 1), dynamic condition = true, Function? onError, void onDone()?, bool? cancelOnError}) Worker
Ignore all changes in listener during time (1 sec by default) or until condition is met (can be a bool expression or a bool Function()), It brings the 1st "value" since the period of time, so if you click a counter button 3 times in 1 sec, it will show you "1" (after 1 sec of the first press) click counter 3 times in 1 sec, it will show you "4" (after 1 sec) click counter 2 times in 1 sec, it will show you "7" (after 1 sec). [...]
once<T>(RxInterface<T> listener, WorkerCallback<T> callback, {dynamic condition = true, Function? onError, void onDone()?, bool? cancelOnError}) Worker
once() will execute only 1 time when condition is met and cancel the subscription to the listener stream right after that. condition defines when callback is called, and can be a bool or a bool Function(). [...]

ScreenType
SmartManagement
GetX by default disposes unused controllers from memory, Through different behaviors. SmartManagement.full SmartManagement.full is the default one. Dispose classes that are not being used and were not set to be permanent. In the majority of the cases you will want to keep this config untouched. If you new to GetX then don't change this. SmartManagement.onlyBuilder only controllers started in init: or loaded into a Binding with Get.lazyPut() will be disposed. If you use Get.put() or Get.putAsync() or any other approach, SmartManagement will not have permissions to exclude this dependency. With the default behavior, even widgets instantiated with "Get.put" will be removed, unlike SmartManagement.onlyBuilders. SmartManagement.keepFactoryJust like SmartManagement.full, it will remove it's dependencies when it's not being used anymore. However, it will keep their factory, which means it will recreate the dependency if you need that instance again.
