Classes

BaseController<State>
An interface for the core functionality implemented by both Controller and StateController.
Bindings
Bindings should be extended or implemented. When using GetMaterialApp, all GetPages and navigation methods (like Get.to()) have a binding property that takes an instance of Bindings to manage the dependencies() (via Get.put()) for the Route you are opening.
BindingsBuilder<T>
Simplifies Bindings generation from a single callback. To avoid the creation of a custom Binding instance per route. [...]
Controller<Event, State>
Takes a Stream of Events as input and transforms them into a Stream of States as output.

GetNavigator

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?>
GetRouterOutlet
GetSocket
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() yourself. [...]
GetWidget<S extends GetLifeCycleBase?>
GetWidget is a great way of quickly access your individual Controller without having to call Get.find() yourself. Get save you controller on cache, so, you can to use Get.create() safely GetWidget is perfect to multiples instance of a same controller. Each GetWidget will have your own controller, and will be call events as onInit and onClose when the controller get in/get out on memory.
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>
GraphQLResponse<T>
HeaderValue
InstanceInfo
InternalFinalCallback<T>
Special callable class to keep the contract of a regular method, and avoid overrides if you extend the class that uses it, as Dart has no final methods. Used in DisposableInterface to avoid the danger of overriding onStart.
LightSubscription<T>
ListenerWidget<State>
Takes a Controller and the listener in response to state changes in the Controller. It should be used for functionality that needs to occur only in response to a state change such as navigation, showing a SnackBar, showing a Dialog, etc... The listener is guaranteed to only be called once for each state change. [...]

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 [...]

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] uses in all it's subclass.

Rx class for String Type.
SimpleBuilder
SnackRoute<T>
StateBase<State>
An interface that extends all functionalities of GetxController and implemented by BaseController.
StateChange<State>
A StateChange represents the change from one State to another. A StateChange consists of the currentState and nextState.
StateController<State>
A StateController is similar to Controller but has no notion of events and relies on methods to emit new states. [...]
SuperController<T>
TransformController<Event, State>
A TransformController is the change from one state to another. Consists of the currentState, an event, and the nextState.

Functions

bodyBytesToString(Stream<List<int>> bodyBytes, Map<String, String> headers) Future<String>
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(). [...]

Enums

PopMode
Enables the user to customize the intended pop behavior [...]
PreventDuplicateHandlingMode
Enables the user to customize the behavior when pushing multiple routes that shouldn't be duplicates
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.
SnackbarStatus
Indicates Status of snackbar SnackbarStatus.OPEN Snack is fully open, SnackbarStatus.CLOSED Snackbar has closed, SnackbarStatus.OPENING Starts with the opening animation and ends with the full snackbar display, SnackbarStatus.CLOSING Starts with the closing animation and ends with the full snackbar dispose
SnackDismissDirection
Indicates the direction in which it is possible to dismiss If vertical, dismiss up will be allowed if SnackPosition.TOP If vertical, dismiss down will be allowed if SnackPosition.BOTTOM
SnackPosition
Indicates if snack is going to start at the TOP or at the BOTTOM
SnackStyle
Indicates if snack will be attached to the edge of the screen or not
