Methods

addChildHandler(TinkWidgetHandler child) → void
canAcceptChildNodes({required String childFieldName, required bool isList}) → void
canHandleDropped(Offset offset, dynamic data) → bool
details is either DragTargetDetails<dynamic> or a string that is the name of the widget dropped or if it was re-arranged then it is the widget itself that was dropped
childEntityField(String fieldName) → EntityField
constructTree(String widgetName, Map<String, Either<TinkWidgetHandler, List<TinkWidgetHandler>>> children, {Map<String, dynamic>? props}) → TinkWidgetHandler
droppedOnRootCanvas<T extends WidgetDefModel<PropertyModel, EventModel>>(T def, Offset offset, dynamic data) → void
Called when a new instance must be created to render on screen
emit<S>(TinkStateEvent<S> current) → CASMLike
override
emitEvent(EventModel event) → void
getChildByName(String name) → ChildWidgetValue?
handleDropped(Offset offset, dynamic data) → void
highlightWidget(Widget widget) → Widget
initDelegate(TinkWidgetHandler delegate, TinkWidgetHandler self) → void
Called to provide an initialisation point for delegate implementations. Must be called by implementations or they must initialise delegate and self themselves AND call this on the delegate
intersects(Offset activityPosition) → TinkWidgetHandler?
listenForAttributeChanges() → void
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
on<S>(String name, CASMEventHandler<S> f, {TinkStateEventType? type = TinkStateEventType.update, bool emitLatest = true, bool subscribe = true, TinkLivenessHandler? state}) → CASMLike
override
onLeave() → bool
onMove(Offset offset, dynamic data) → bool
onNodeTreeAccept(TreeNodeHandler handler) → dynamic
override
onNodeTreeAcceptWithDetails(DragTargetDetails<TreeNodeHandler> details) → dynamic
override
onNodeTreeLeave(TreeNodeHandler? details) → dynamic
override
onNodeTreeMove(DragTargetDetails<TreeNodeHandler> details) → dynamic
override
onNodeTreeWillAccept(TreeNodeHandler? dropped) → dynamic
override
onUpdate(EntityEventSource src) → void
When invoked, the entity should use the event source to obtain the most recent value for each of its fields, internally performing an update where necessary Implementations can override this if for example they only want to update selected fields they can use EntityEventSource.valueOf
override
postDeserialisation() → void
override
removeChild(TinkWidgetHandler oldChild) → void
removeChildByName(String name) → void
render() → Widget
rerender(dynamic fn()) → void
If this widget has setup a runtime context then call setState which will trigger a rebuild If it hasn't then the whole screen will be re-built to force the update to become visible to the user Obviously rebuilding the screen is more expensive so most widgets should provide a TinkWidgetRuntimeContext when in runtime mode.
save(CASMLike casm) → dynamic
override
setArg(String name, dynamic value) → void
setAttr(TinkWidgetAttribute attr, TinkAttributeEvent current) → void
Called when the given attribute has been given a new value. This assumes the attribute can/should be directly set in the args passed to the widget
setChild(String name, ChildWidgetValue value) → void
setChildIfAbsent(String name, ChildWidgetValue value()) → ChildWidgetValue
setNonListChild(String argName, TinkWidgetHandler child) → void
showSettingsHandle() → void
showWidgetProperties(BuildContext context, StateSetter setState) → Widget
subscribeToUpdates(CASMLike casm) → dynamic
override
swapChild(TinkWidgetHandler oldChild, TinkWidgetHandler newChild) → void
toString() → String
A string representation of this object.
inherited
triggerEditorRebuild(VoidCallback fn) → void

Operators

operator ==(Object other) → bool
The equality operator.
