state_manager library

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

Classes

Bind<T>
BindElement<T>
The BindElement is responsible for injecting dependencies into the widget tree so that they can be observed
Binder<T>
Binding
Binding should be extended. When using JetMaterialApp, all JetPages and navigation methods (like Jet.to()) have a binding property that takes an instance of Bindings to manage the dependencies() (via Jet.put()) for the Route you are opening.
Binds
Computed<T>
A computed observable that automatically tracks dependencies and recomputes when any of its dependencies change.
CustomStatus<T>
EmptyStatus<T>
Engine
ErrorStatus<T, S>
FastList<T>
FullLifeCycleController
A controller that can observe the full app lifecycle.
GetListenable<T>
GetNotifier<T>
GetNotifier has a native status and state implementation, with the Get Lifecycle
GetStatus<T>
JetBuilder<T extends JetxController>
JetInterface
JetInterface allows any auxiliary package to be merged into the "Jet" class through extensions
JetResponsiveView<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.
JetResponsiveWidget<T extends JetLifeCycleMixin>
JetView<T>
JetView is a great way of quickly access your Controller without having to call Jet.find<AwesomeController>() yourself.
JetWidget<S extends JetLifeCycleMixin>
JetWidget is a great way of quickly access your individual Controller without having to call Jet.find<AwesomeController>() yourself. Jet save you controller on cache, so, you can to use Jet.create() safely JetWidget is perfect to multiples instance of a same controller. Each JetWidget will have your own controller, and will be call events as onInit and onClose when the controller get in/get out on memory.
JetX<T extends JetLifeCycleMixin>
JetxController
A base controller class that provides state management functionality.
JetXState<T extends JetLifeCycleMixin>
LoadingStatus<T>
MiniStream<T>
MiniSubscription<T>
Node<T>
Observer
Obx
The simplest reactive widget in JetX.
ObxElement
ObxError
ObxStatelessWidget
A StatelessWidget than can listen reactive changes.
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 JetX 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
A base controller class for reactive state management using Rx variables.
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<T> uses in all it's subclass.
RxList<E>
Create a list similar to List<T>
RxMap<K, V>
Rxn<T>
RxnBool
RxnDouble
RxnInt
RxnNum
RxnString
Rx class for String Type.
RxNum
RxSet<E>
RxString
Rx class for String Type.
StateController<T>
A controller that manages state for asynchronous operations.
SuccessStatus<T>
SuperController<T>
A controller that combines full lifecycle management with state management.
Value<T>
ValueBuilder<T>
Manages a local state like ObxValue, but uses a callback instead of a Rx value.
ValueBuilderState<T>
Worker
Workers

Enums

ScreenType
SmartManagement
Defines how JetX manages the lifecycle and disposal of controllers and dependencies.

Mixins

FullLifeCycleMixin
A mixin that provides full lifecycle callbacks for the controller.
GetSingleTickerProviderStateMixin
Used like SingleTickerProviderMixin but only with Get Controllers. Simplifies AnimationController creation inside JetxController.
GetTickerProviderStateMixin
Used like TickerProviderMixin but only with Get Controllers. Simplifies multiple AnimationController creation inside JetxController.
JetResponsiveMixin
RxObjectMixin<T>
global object that registers against JetX and Obx, and allows the reactivity of those Widgets and Rx values.
ScrollMixin
A mixin that provides scroll-based data fetching capabilities.
SingleGetTickerProviderMixin
Used like SingleTickerProviderMixin but only with Get Controllers. Simplifies AnimationController creation inside JetxController.
StatelessObserverComponent
a Component that can track changes in a reactive variable
StateMixin<T>

Functions

debounce<T>(GetListenable<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 JetX
ever<T>(GetListenable<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>(GetListenable<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>(GetListenable<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().
