node in the semantics tree. Otherwise, the semantics will be
merged with the semantics of any ancestors (if the ancestor allows that).

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 thedata
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.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
