Properties

allowImplicitScrolling → bool
Controls whether the widget's pages will respond to RenderObject.showOnScreen, which will allow for implicit accessibility scrolling.
finalinherited
cacheExtent → int
cache page count default is 0. if cacheExtent is 1, it has two pages in cache null is infinity, it will cache all pages
final
childrenDelegate → SliverChildDelegate
A delegate that provides the children for the _PageView.
finalinherited
clipBehavior → Clip
The content will be clipped (or not) according to this option.
finalinherited
controller → PageController
An object that can be used to control the position to which this page view is scrolled.
finalinherited
dragStartBehavior → DragStartBehavior
Determines the way that drag start behavior is handled.
finalinherited
elHorizontalScroll → Widget

Available on Widget, provided by the ElWidgetExt extension

监听鼠标水平滚动（仅限桌面端生效），其后代滚动小部件必须在 widget 层指定 ScrollController
no setter
hashCode → int
The hash code for this object.
no setterinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onPageChanged → ValueChanged<int>?
Called whenever the page in the center of the viewport changes.
finalinherited
padEnds → bool
Whether to add padding to both ends of the list.
finalinherited
pageSnapping → bool
Set to false to disable page snapping, useful for custom scroll behavior.
finalinherited
physics → ScrollPhysics?
How the page view should respond to user input.
finalinherited
restorationId → String?
Restoration ID to save and restore the scroll offset of the scrollable.
finalinherited
reverse → bool
Whether the page view scrolls in the reading direction.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scrollBehavior → ScrollBehavior?
ScrollBehaviors also provide ScrollPhysics. If an explicit ScrollPhysics is provided in physics, it will take precedence, followed by scrollBehavior, and then the inherited ancestor ScrollBehavior.
finalinherited
scrollDirection → Axis
The Axis along which the scroll view's offset increases with each page.
finalinherited
shouldIgnorePointerWhenScrolling → bool
Whether the contents of the widget should ignore PointerEvent inputs.
final

Methods

createElement() → StatefulElement
Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<ExtendedPageView>
Creates the mutable state for this widget at a given location in the tree.
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
elScrollbarBehavior(BuildContext context, ElScrollBehavior behavior) → Widget

Available on Widget, provided by the ElWidgetExt extension

合并祖先 ElScrollBehavior 的默认配置，如果不需要尊重祖先配置， 请直接使用 ScrollConfiguration 覆盖即可
noScrollbarBehavior(BuildContext context, {Key? key, bool? overscroll, Set<PointerDeviceKind>? dragDevices, MultitouchDragStrategy? multitouchDragStrategy, Set<LogicalKeyboardKey>? pointerAxisModifiers, ScrollPhysics? physics, TargetPlatform? platform, ScrollViewKeyboardDismissBehavior? keyboardDismissBehavior, bool enabled = true}) → Widget

Available on Widget, provided by the ElWidgetExt 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设置此扩展，可以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

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.
