Properties

allowImplicitScrolling → bool: If allowImplicitScrolling is true, the PageView will participate in accessibility scrolling more like a ListView, where implicit scroll actions will move to the next page rather than into the contents of the PageView.
finalinherited
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
hashCode → int: The hash code for this object.
no setterinherited
hitTestBehavior → HitTestBehavior: Defines the behavior of gesture detector used in this Scrollable.
finalinherited
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?: A ScrollBehavior that will be applied to this widget individually.
finalinherited
scrollCacheExtent → ScrollCacheExtent: The viewport has an area before and after the visible area to cache items that are about to become visible when the user scrolls.
finalinherited
scrollDirection → Axis: The Axis along which the scroll view's offset increases with each page.
finalinherited

Methods

createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → State<PageView>: Creates the mutable state for this widget at a given location in the tree.
inherited
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
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.
