Properties

attributedDecreasedValue → AttributedString?
final
attributedHint → AttributedString?
final
attributedIncreasedValue → AttributedString?
final
attributedLabel → AttributedString?
final
attributedValue → AttributedString?
final
blockUserActions → bool
Whether to block user interactions for the rendering subtree.
final
button → bool?
final
checked → bool?
final
child → JsonWidgetData?
final
container → bool
If container is true, this widget will introduce a new node in the semantics tree. Otherwise, the semantics will be merged with the semantics of any ancestors (if the ancestor allows that).
final
currentValueLength → int?
final
customSemanticsActions → Map<CustomSemanticsAction, void Function()>?
final
decreasedValue → String?
final
enabled → bool?
final
excludeSemantics → bool
Whether to replace all child semantics with this node.
final
expanded → bool?
final
explicitChildNodes → bool
Whether descendants of this widget are allowed to add semantic information to the SemanticsNode annotated by this widget.
final
focusable → bool?
final
focused → bool?
final

Methods

build({ChildWidgetBuilder? childBuilder, required BuildContext context, JsonWidgetRegistry? registry}) → Widget
Convenience method that can build the widget this data object represents. This is the equilivant of calling: builder.build and passing this in as the data parameter.
inherited
copyWith({dynamic jsonWidgetArgs, JsonWidgetBuilder? jsonWidgetBuilder, Set<String>? jsonWidgetListenVariables, String? jsonWidgetId, JsonWidgetRegistry? jsonWidgetRegistry, String? jsonWidgetType}) → JsonWidgetData
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toJson() → Map<String, dynamic>
Abstract function that concrete classes must implement. This must encode the internal data model to a JSON compatible representation.
inherited
toString() → String
Returns the string encoded JSON representation for this class. This will remove all null values and empty collections from the returned string.

Operators

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