Properties
- allowImplicitScrolling → bool
-
Controls whether the widget's pages will respond to
RenderObject.showOnScreen, which will allow for implicit accessibility
scrolling.
final
- childrenDelegate → SliverChildDelegate
-
A delegate that provides the children for the GesturePageView.
final
- clipBehavior → Clip
-
The content will be clipped (or not) according to this option.
final
- controller → ExtendedPageController
-
An object that can be used to control the position to which this page
view is scrolled.
final
- dragStartBehavior → DragStartBehavior
-
Determines the way that drag start behavior is handled.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited

no setter -
onPageChanged
→ ValueChanged<
int> ? -
Called whenever the page in the center of the viewport changes.
final
- paddingZero → Widget
-
Available on Widget, provided by the WidgetPaddingX extension
no setter - padEnds → bool
-
Whether to add padding to both ends of the list.
final
