StyleSpec<T extends Spec<T>> class

A widget specification that wraps a pure Spec with widget metadata.

This class provides a way to add widget-level metadata (animation, modifiers) to any Spec without requiring the Spec to extend StyleSpec directly. This promotes clean separation between data specs and widget metadata.

Example:

// Pure data spec
final boxSpec = BoxSpec(padding: EdgeInsets.all(16));

// Wrapped with metadata
final wrappedSpec = StyleSpec(
  spec: boxSpec,
  animation: AnimationConfig.curve(),
);

Methods

copyWith({T? spec, AnimationConfig? animation, List<WidgetModifier<WidgetModifier>>? widgetModifiers}) → StyleSpec<T>
Creates a copy of this StyleSpec with the given fields replaced by the new values.
override
createBuilder(Widget builder(BuildContext context, T spec)) → Widget

Available on StyleSpec<T>, provided by the StyleSpecWidgetBuilder extension

Creates a widget using a custom builder function that receives the resolved spec.
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
override
getDiff(Equatable other) → Map<String, String>
Returns a map of properties that differ between this object and another.
inherited
lerp(covariant StyleSpec<T>? other, double t) → StyleSpec<T>
Linearly interpolates between this StyleSpec and another.
override
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
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
