Properties

buttonLoading → bool

no setter, inherited

empty → bool

no setter, inherited

error → bool

no setter, inherited

errorMessage → String

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

hasListeners → bool

no setter, inherited

initialized → bool

Checks whether the controller has already been initialized.

isClosed → bool

Checks whether the controller has already been closed.

normal → bool

no setter, inherited

onDelete → InternalFinalCallback<void>

Internal callback that starts the cycle of this controller.

final, 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

pageState → PageState

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

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

afterGetData() → void

获取数据后

beforeGetData() → Future

获取数据前执行

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

doLoading() → void

inherited

endLoading() → void

inherited

findModel<S>({String? tag}) → S?

获取 model

inherited

getData() → Future<T>

获取初始化加载数据

getSpData() → T?

获取 Sp 中缓存的数据

hideKeyboard() → void

关闭键盘

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

notifyChildrens() → void

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.

override

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

refreshData() → Future<void>

刷新数据-从网络获取

refreshGroup(Object id) → void

inherited

refreshWithLoading() → dynamic

初始化数据

override

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

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

updateData(void fn(T? val)) → dynamic

更新 data 内数据

Operators

operator ==(Object other) → bool

The equality operator.
