Constructors

InfiniteListView({Key? key, Axis scrollDirection = Axis.vertical, bool reverse = false, ScrollController? controller, bool? primary, ScrollPhysics? physics, EdgeInsetsGeometry? padding, double? cacheExtent, DragStartBehavior dragStartBehavior = DragStartBehavior.start, ScrollViewKeyboardDismissBehavior? keyboardDismissBehavior, String? restorationId, Clip clipBehavior = Clip.hardEdge, double? itemExtent, Widget? prototypeItem, bool addAutomaticKeepAlives = true, bool addRepaintBoundaries = true, bool addSemanticIndexes = true, required PaginationDelegate delegate, bool shrinkWrap = false})
The InfiniteListView widget in Flutter is a specialized version of the ListView.builder widget that is designed for handling large datasets efficiently. It uses a pagination approach to load and display data in pages as the user scrolls down the list. This helps to improve performance and reduce memory usage, especially when dealing with large datasets that cannot be fully loaded into memory at once.

Properties

addAutomaticKeepAlives → bool
The addAutomaticKeepAlives argument corresponds to the SliverChildBuilderDelegate.addAutomaticKeepAlives property.
final
addRepaintBoundaries → bool
The addRepaintBoundaries argument corresponds to the SliverChildBuilderDelegate.addRepaintBoundaries property.
final
addSemanticIndexes → bool
The addSemanticIndexes argument corresponds to the SliverChildBuilderDelegate.addSemanticIndexes property.
final
anchor → double
The relative position of the zero scroll offset.
finalinherited
cacheExtent → double?
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
center → Key?
The first child in the GrowthDirection.forward growth direction.
finalinherited
clipBehavior → Clip
The content will be clipped (or not) according to this option.
finalinherited
controller → ScrollController?
An object that can be used to control the position to which this scroll view is scrolled.
finalinherited
delegate → PaginationDelegate
The PaginationDelegate contains all the necessary information for a paginated layout, such as the item count, item builder, loading indicator builder, error indicator builder, no more items indicator builder, loading state, error state, and more.
final
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
itemExtent → double?
If non-null, forces the children to have the given extent in the scroll direction.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
keyboardDismissBehavior → ScrollViewKeyboardDismissBehavior?
The ScrollViewKeyboardDismissBehavior defines how this ScrollView will dismiss the keyboard automatically.
finalinherited
padding → EdgeInsetsGeometry?
The amount of space by which to inset the children.
finalinherited
paintOrder → SliverPaintOrder
The order in which to paint the slivers; equivalently, the order in which to arrange them in the z-direction.
finalinherited
physics → ScrollPhysics?
How the scroll view should respond to user input.
finalinherited
primary → bool?
Whether this is the primary scroll view associated with the parent PrimaryScrollController.
finalinherited
prototypeItem → Widget?
If non-null, forces the children to have the same extent as the given widget in the scroll direction.
final
restorationId → String?
Restoration ID to save and restore the scroll offset of the scrollable.
finalinherited
reverse → bool
Whether the scroll 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
scrollDirection → Axis
The Axis along which the scroll view's offset increases.
finalinherited
semanticChildCount → int?
The number of children that will contribute semantic information.
finalinherited
shrinkWrap → bool
Whether the extent of the scroll view in the scrollDirection should be determined by the contents being viewed.
