Value<T> class

This is a experimental feature. Meant to be used with SimpleBuilder, it auto-registers the variable like Rx() does with Obx().

Properties

hashCode int
The hash code for this object. [...]
read-only, inherited
initialized bool
Checks whether the controller has already been initialized.
read-only, inherited
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.
final, inherited
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited
value ↔ T
read / write

Methods

addListener(GetStateUpdate listener) VoidCallback
inherited
addListenerId(String key, GetStateUpdate listener) VoidCallback
inherited
disposeId(String 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
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
onClose() → void
Called before onDelete method. onClose might be used to dispose resources used by the controller. Like closing events, or streams before the controller is destroyed. Or dispose objects that can potentially create some memory leaks, like TextEditingControllers, AnimationControllers. Might be useful as well to persist some data on disk.
inherited
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
toString() String
A string representation of this object. [...]
inherited
update([List<String> 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

Operators

operator ==(Object other) bool
The equality operator. [...]
