GetxControllerPlus class abstract

An extended version of GetX GetxController

Features:

  • Awareness of a running process with duration which requires users to be notified
  • Convenient error handler macro functions
  • Encouraging decoupling of Views and View Logics
  • Provided with support widgets

Typical usage:

class MySmartController extends GetxControllerPlus {
// ...
}

class MySmartWidget extends GetView<MySmartController> {
// ...
}

class MyOtherSmartWidget extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    final controller = Get.put(
      MySmartController(),
    );

    // ...
  }
}

Properties

hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
no setterinherited
initialized → bool
Checks whether the controller has already been initialized.
no setterinherited
isClosed → bool
Checks whether the controller has already been closed.
no setterinherited
isLoading ↔ bool
This value determines if a process is currently running and user needs to be notified about it. Reflected by the widgets built by this value.
getter/setter pairoverride
listeners → int
no setterinherited
onDelete → InternalFinalCallback<void>
Internal callback that starts the cycle of this controller.
finalinherited
onStart → InternalFinalCallback<void>
Called at the exact moment the widget is allocated in memory. It uses an internal "callable" type, to avoid any @overrides in subclases. This method should be internal and is required to define the lifetime cycle of the subclass.
finalinherited
onWillPop → WillPopCallback
Default implementation of WillPopCallback. Returns false if is isLoading
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

Methods

$configureLifeCycle() → void
inherited
addListener(GetStateUpdate listener) → Disposer
Register a closure to be called when the object notifies its listeners.
inherited
addListenerId(Object? key, GetStateUpdate listener) → Disposer
inherited
dispose() → void
inherited
disposeId(Object id) → void
To dispose an id from future updates(), this ids are registered by GetBuilder() or similar, so is a way to unlink the state change with the Widget from the Controller.
inherited
handleError(Object err) → FutureOr<void>
PROTECTED
override
isLoadingByTag(String tag) → bool
Works the same like isLoading, but with a specific tag. Typically used in a screen where there are more than one waitable processes and the user needs to be notified by a separate display.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyChildrens() → void
inherited
onClose() → void
Disposes resources as usual in a typical onClose event.
override
onInit() → void
Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.
inherited
onReady() → void
Called 1 frame after onInit(). It is the perfect place to enter navigation events, like snackbar, dialogs, or a new route, or async request.
inherited
refresh() → void
inherited
refreshGroup(Object id) → void
inherited
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that the object notifies.
inherited
removeListenerId(Object id, VoidCallback listener) → void
inherited
setErrorHandler<T>(ErrorHandlerCallback<T> handler) → void
Provides a handler Function to handle any calls from handleError. Handles T which is error-like object which is typically thrown by try-catch blocks inside the GetxControllerPlus scope.
override
setIsLoadingByTag(String tag, bool value) → void
PROTECTED
override
toString() → String
A string representation of this object.
inherited
update([List<Object>? ids, bool condition = true]) → void
Rebuilds GetBuilder each time you call update(); Can take a List of ids, that will only update the matching GetBuilder( id: ), ids can be reused among GetBuilders like group tags. The update will only notify the Widgets, if condition is true.
inherited
wait<T>(Future<T> computation, {String? tag}) → Future<T?>
PROTECTED
override

Operators

operator ==(Object other) → bool
The equality operator.
inherited

Static Properties

defaultErrorHandlers ← Map<Type, ErrorHandlerCallback>
Sets a default set of Error Handlers which is preferable scenarios like:
