Properties
- currentUserId → String?
-
Current user id, used to decide which ownership badge / actions to
render. When null, the view reads from
currentUserProvider.final - domainName → String?
-
final
- domainSlug → String
-
final
- embedded → bool
-
True when the view sits inside another scrolling list (wide layout).
Suppresses the inner scroll view so the parent ListView owns scrolling.
final
- family → FamilyGroup?
-
Family group for the active domain when known by the parent (wide
layout). On narrow screens, TopicTreeView resolves this from the
current domain's
domain_familyagainst the loaded domains list.final - hashCode → int
-
The hash code for this object.
no setterinherited
- key → Key?
-
Controls how one widget replaces another widget in the tree.
finalinherited
- onSelectVariant → void Function(String family, String variant, String domainId)?
-
Called when the user picks a different variant from the picker.
On the wide layout, the parent updates the active-domain id; on narrow
(when null), the view falls back to navigating to the new variant's
route.
final
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
animate(
{Key? key, List< Effect> ? effects, AnimateCallback? onInit, AnimateCallback? onPlay, AnimateCallback? onComplete, bool? autoPlay, Duration? delay, AnimationController? controller, Adapter? adapter, double? target, double? value}) → Animate -
Available on Widget, provided by the AnimateWidgetExtensions extension
Wraps the target Widget in an Animate instance, and returns the instance for chaining calls. Ex.myWidget.animate()is equivalent toAnimate(child: myWidget). -
createElement(
) → ConsumerStatefulElement -
Creates a StatefulElement to manage this widget's location in the tree.
inherited
-
createState(
) → ConsumerState< TopicTreeView> -
Creates the mutable state for this widget at a given location in the tree.
override
-
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
