const

Properties

adjustPosition → ElPopupAdjustPosition
弹出层如何触发重新定位，默认 ElPopupAdjustPosition.boundary， 当目标方向放不下弹窗内容时，才会调整方向
final
alignment → ElPopupAlignment?
弹出层的对齐位置，如果设置了 hoverDelayShow 延迟显示， 那么默认对齐为 ElPopupAlignment.float，否则默认为 ElPopupAlignment.bottom
final
builder → Widget Function(BuildContext context, ElPopupState<ElPopup> state)
构建代理子组件
finalinherited
child → Widget
链接的目标子组件，弹窗会在该小部件周围显示
final
constraints → BoxConstraints?
设置弹出层尺寸范围，如果最大最小宽高相等，则弹窗布局性能将会提高一倍
final
coverTarget → bool?
弹窗是否覆盖目标组件
final
duration → Duration?
弹出层的过渡时间，默认 El.duration
finalinherited
edgeSpacing → double?
弹出层与 Overlay 画布之间的间隔
final
groupId → Object?
点击外部分组 id，默认以当前 State 的 hashCode 作为分组 id
final
hashCode → int
The hash code for this object.
no setterinherited
keepAlive → bool
关闭弹出层时是否保留状态
finalinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
modelType → ElModelValueType
双向绑定类型
finalinherited
modelValue → dynamic
支持基础数据类型和响应式变量，如果变量类型为 ValueNotifier， 则无需监听 onChanged 方法手动更新 UI。以 ElSwitch 组件为例：
finalinherited
onChanged → ValueChanged<bool?>?
变量更新通知方法
finalinherited
onInsert → VoidCallback?
插入弹出层回调
finalinherited
onRemove → VoidCallback?
移除弹出层回调
finalinherited
overlayBuilder → Widget Function(BuildContext context)
构建弹出层小部件
finalinherited
overlayId → Object?
指定弹出层的 id 标识，默认为当前 State 的 hashCode，如果弹出层的 State 生命周期不稳定， 你应当指定弹出层的 id 标识，这样可以避免一些意外的 bug。
finalinherited
overlayState → ElOverlayState?
将弹出层直接挂载到指定的 ElOverlay 实例上
finalinherited
preventBack → bool
是否拦截物理返回（仅限安卓）
finalinherited
removeBehavior → ElPopupRemoveBehavior?
点击弹窗外部所应用的移除策略，默认为 ElPopupRemoveBehavior.tapDown，但有些弹窗可能是其他策略
final
rootOverlay → bool
将弹出层挂载到顶级 ElOverlay 实例上
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
show → dynamic
手动控制弹出层的显示隐藏（支持双向绑定）
finalinherited
spacing → double?
弹出层与目标小部件之间的间隔
final
transitionBuilder → Widget Function(BuildContext context, Widget child)
构建弹出层动画
finalinherited

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<ElPopup>
Creates the mutable state for this widget at a given location in the tree.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
noScrollbarBehavior(BuildContext context, {Key? key, bool? overscroll, bool enabled = true}) → Widget

Available on Widget, provided by the FlutterWidgetExt extension

不使用祖先提供的默认滚动条，当使用自定义滚动条时请添加此扩展方法，防止与祖先提供的默认滚动条重叠
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
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
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A short, textual description of this widget.
