Properties

checkMinutesInterval ↔ int
定时健康检查的间隔（分钟）。
getter/setter pair
enableHealthCheck ↔ bool
是否启用网络健康检查。
getter/setter pair
extraUrls → List<String>
参与网络健康检查的额外地址。
final
fastResponseTime ↔ int
最近一次健康检查中最快节点的响应时间（毫秒）。
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
no setterinherited
healthCheckDebounceSeconds ↔ int
连接变化后执行健康检查前的防抖时间（秒）。
getter/setter pair
initialized → bool
Checks whether the controller has already been initialized.
no setterinherited
isClosed → bool
Checks whether the controller has already been closed.
no setterinherited
isConnected → RxBool
当前是否存在网络连接。
final
listeners → int
no setterinherited
netType → Rx<NetworkType>
当前网络类型。
final
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
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
status → Rx<NetworkStatus>
当前网络健康状态。
final

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
checkConnectivity() → Future<void>
获取并更新当前网络连接状态。
checkNetworkHealth({int slowThresholdMs = 3000, int timeoutMs = 10000}) → Future<NetworkStatus>
检查网络是否可访问，并以最快成功请求的响应时间判定健康状态。
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
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.
override
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
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
setHealthCheckDebounceSeconds(int seconds) → void
设置连接变化后健康检查的防抖时间（秒）。
setHealthCheckEnabled(bool enabled) → void
设置网络健康检查开关。
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

Operators

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