ElLinkPopupState()

Properties

alignment → ElPopupAlignment
弹出层对齐位置，如果设置了延迟显示，那么默认弹出层对齐为浮动
no setterinherited
animationController ↔ AnimationController
显示、隐藏弹窗动画控制器
latefinalinherited
animationDuration → Duration
声明默认的动画持续时间
no setterinherited
bottomMaxHeight → double
popup 上下对齐时底部最大高度
no setterinherited
childAlignBottom → bool
目标 child 处于偏下位置
no setterinherited
childAlignLeft → bool
目标 child 处于偏左位置
no setterinherited
childAlignRight → bool
目标 child 处于偏右位置
no setterinherited
childAlignTop → bool
目标 child 处于偏上位置
no setterinherited
childKey → GlobalKey<State<StatefulWidget>>
finalinherited
childPosition → Offset
目标 child 相对 Overlay 的位置
no setterinherited
childSize → Size
目标 child 的大小（当插入 popup 时初始化）
no setterinherited
context → BuildContext
The location in the tree where this widget builds.
no setterinherited
edgeSpacing → double
弹出层与 Overlay 画布之间的间隔
no setterinherited
groupId → Object
点击外部分组 id
no setter
hashCode → int
The hash code for this object.
no setterinherited
ignoreOnceListener ↔ bool?
忽略一次响应式变量监听方法，有时候更新响应式变量不希望触发监听函数（需要手动控制动画）， 你可以将此变量设置为 true，监听拦截后会自动重置它
getter/setter pairinherited
indexNotify → ValueNotifier<int>
no setterinherited
isCenter → bool
是否为居中对齐
no setterinherited
isFloat → bool
是否为浮动对齐
no setterinherited
isTight → bool
弹出层的约束是否为强制最大、最小宽高
no setterinherited
finalinherited
layerOffset → Offset
LayerLink 链接的偏移位置
no setterinherited
leftMaxWidth → double
popup 左右对齐时左侧最大宽度
no setterinherited
localPosition ↔ Offset?
指针在目标子组件上的位置，只有当 float 浮动对齐时才会设置此变量
getter/setter pairinherited
lockObsUpdate ↔ bool
锁定响应式变量更新，将此变量设置为 true 后，可以避免任何外部因素意外地修改 obs
getter/setter pairinherited
modelValue ↔ bool?
返回响应式原始数据
getter/setter pairinherited
mounted → bool
Whether this State object is currently in a tree.
no setterinherited
obs ↔ Obs<bool?>
latefinalinherited
overlayEntry ↔ ElOverlayEntry?
弹出层实例对象
getter/setter pairinherited
overlayEntryKey → GlobalKey<State<StatefulWidget>>
finalinherited
overlayId → Object
弹出层 id 唯一标识符，默认为 hashCode
no setterinherited
overlaySize → Size
当前浮层画布尺寸
no setterinherited
overlayState → ElOverlayState
管理弹出层的 Overlay 对象
no setterinherited
popupAlignment ↔ ElPopupAlignment?
默认对齐方式可能放不下内容，所以在渲染前会进行一次预估，此变量是弹出层最终的对齐位置
getter/setter pairinherited
popupConstraints → BoxConstraints
弹出层默认的尺寸约束，如果用户没有指定约束条件，则 overlaySize 将直接作为弹出层默认最大尺寸， 若用户指定了约束条件，则将 widget.constraints 与 overlaySize 进行联合取值。
no setter
popupSize → Size
弹出层尺寸
no setterinherited
positionType → _ElPopupPositionType?
弹出层的基本类型，如果 alignment 为 center 类型，那么该属性为 null
no setterinherited
refreshOverlay ↔ VoidCallback?
刷新弹窗内容，此方法会触发 buildOverlay 重建
getter/setter pairinherited
removeBehavior → ElPopupRemoveBehavior
点击弹窗外部应用的移除策略，不同弹窗应用的策略可能并不相同
no setter
rightMaxWidth → double
popup 左右对齐时右侧最大宽度
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
safePadding → EdgeInsets
适配 SafeArea 安全区域
no setterinherited
scrollNotify ↔ Listenable
感知滚动通知，当发生滚动时可能需要调整弹出层位置
getter/setter pair
spacing → double
弹出层与目标小部件之间的间隔
no setterinherited
topMaxHeight → double
popup 上下对齐时顶部最大高度
no setterinherited
widget → T
The current configuration.
no setterinherited

Methods

activate() → void
Called when this object is reinserted into the tree after having been removed via deactivate.
inherited
bindingListener() → void
执行 initState 初始化时绑定响应式监听，通过 modelValue 来驱动弹窗的显示、隐藏
inherited
build(BuildContext context) → Widget
Describes the part of the user interface represented by this widget.
override
buildFloatEvent(BuildContext context, Widget child) → Widget
若是浮动对齐，则需要包裹一层事件小部件来访问指针位置
buildOverlay(BuildContext context) → Widget
构建 overlay 内容小部件
override
buildPopup(BuildContext context) → Widget
继承 ElLinkPopup 的子类若要自定义内容，应当重写此方法，而不是 buildOverlay 方法
createSimulation({required bool forward}) → Simulation?
使用弹簧动画来驱动 animationController
inherited
createTicker(TickerCallback onTick) → Ticker
Creates a ticker with the given callback.
inherited
deactivate() → void
Called when this object is removed from the tree.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
didChangeDependencies() → void
Called when a dependency of this State object changes.
inherited
didUpdateWidget(covariant T oldWidget) → void
Called whenever the widget configuration changes.
inherited
dispose() → void
Called when this object is removed from the tree permanently.
override
forward() → TickerFuture
前进动画
inherited
initState() → void
Called when this object is inserted into the tree.
override
insertOverlay() → void
插入弹出层
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notify() → void
强制触发响应变更，ValueNotifier 有 2 种情况无法自动响应副作用函数：
inherited
obsBuild(BuildContext context) → Widget
监听 obs 变量更新，重建 obsBuilder 代码块
inherited
obsBuilder(BuildContext context) → Widget

onInsert() → void
override
onRemove() → void
override
reassemble() → void
Called whenever the application is reassembled during debugging, for example during hot reload.
inherited
removeOverlay() → void
移除弹出层
inherited
reverse() → TickerFuture
返回动画
inherited
reverseCallback() → void
返回动画回调
inherited
setState(VoidCallback fn) → void
Notify the framework that the internal state of this object has changed.
inherited
showOverlay() → void
当 overlayEntry 还存在时，可以调用此方法直接显示弹出层，通常有 2 种情况会调用它：
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toggle() → void
切换显示、隐藏弹窗
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
