Constructors

ExtendedNestedScrollView({Key? key, ScrollController? controller, Axis scrollDirection = Axis.vertical, bool reverse = false, ScrollPhysics? physics, required NestedScrollViewHeaderSliversBuilder headerSliverBuilder, required int innerControllerCount, required int activeControllerIndex, required Widget bodyBuilder(BuildContext context, List<ScrollController> innerControllers), DragStartBehavior dragStartBehavior = DragStartBehavior.start, bool floatHeaderSlivers = false, Clip clipBehavior = Clip.hardEdge, String? restorationId, ScrollBehavior? scrollBehavior, bool onNotification(Notification notification)?})
const

Properties

activeControllerIndex int
The active inner scroll controller index. Note that only the active controller's ScrollPosition will attach to ExtendedNestedScrollView outer nested scroll controller. Note that this value should be larger than innerControllerCount.
final
bodyBuilder Widget Function(BuildContext context, List<ScrollController> innerControllers)
The body widget builder. This builder passes all inner scroll controllers as its second parameter, and it should be used for each page's scroll view. Note that possibly you need to wrap some pages with PrimaryScrollController.
final
clipBehavior Clip
final
controller ScrollController?
final
dragStartBehavior DragStartBehavior
final
floatHeaderSlivers bool
final
hashCode int
The hash code for this object.

headerSliverBuilder NestedScrollViewHeaderSliversBuilder
final
innerControllerCount int
The inner scroll controller count (or page count). Note that this value should be larger than zero.
final
key Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onNotification → (bool Function(Notification notification)?)
The function called when a notification of the appropriate type arrives at this location in the tree, and it is the same as NotificationListener.onNotification.
final
physics ScrollPhysics?
final
restorationId String?
final
reverse bool
final
runtimeType Type
A representation of the runtime type of the object.
