InViewNotifierList class

builds a ListView and notifies when the widgets are on screen within a provided area.

The constructor takes an IndexedWidgetBuilder which builds the children on demand. It's just like the ListView.builder.

InViewNotifierList({Key? key, int? itemCount, required IndexedWidgetBuilder builder, List<String> initialInViewIds = const [], double endNotificationOffset = 0.0, VoidCallback? onListEndReached, Duration throttleDuration = const Duration(milliseconds: 200), Axis scrollDirection = Axis.vertical, required IsInViewPortCondition isInViewPortCondition, ScrollController? controller, EdgeInsets? padding, ScrollPhysics? physics, bool reverse = false, bool? primary, bool shrinkWrap = false, bool addAutomaticKeepAlives = true})

child → ScrollView: The widget that should be displayed in the InViewNotifier.
finalinherited
endNotificationOffset → double: The distance from the bottom of the list where the onListEndReached should be invoked.
finalinherited
hashCode → int: The hash code for this object.
no setterinherited
initialInViewIds → List<String>: The String list of ids of the child widgets that should be initialized as inView when the list view is built for the first time.
finalinherited
isInViewPortCondition → IsInViewPortCondition: The function that defines the area within which the widgets should be notified as inView.
finalinherited
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
onListEndReached → VoidCallback?: The function that is invoked when the list scroll reaches the end or the endNotificationOffset if provided.
finalinherited
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
scrollDirection → Axis: The axis along which the scroll view scrolls.
finalinherited
throttleDuration → Duration: The duration to be used for throttling the scroll notification. Defaults to 200 milliseconds.
finalinherited

createElement() → StatefulElement: Creates a StatefulElement to manage this widget's location in the tree.
inherited
createState() → _InViewNotifierState: 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}) → 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.
