CheckboxRenderBase class abstract

Shared structural base for themed checkbox renderers.

Checkboxes diverge more than buttons or cards: the box element and the checkmark differ structurally per theme. This base therefore factors the parts that are genuinely identical and error-prone — the group/item interaction attribute wiring, the wrapper element and click event, and the label/description block scaffold — while leaving the visual box and the theme-specific style values to abstract members the subclass supplies.

This base lives in core and depends only on core props and interaction helpers; it must never depend on a theme package.

Methods

build(BuildContext context) → Component

Describes the part of the user interface represented by this component.

override

buildBox(CheckboxProps props, Map<String, String> itemAttrs) → Component

Builds the visual checkbox box (and its checkmark). itemAttrs are the resolved group-item/interaction attributes that must be placed on the box.

createElement() → Element

Creates a StatelessElement to manage this component's location in the tree.

inherited

descriptionTextStyles(CheckboxProps props) → Map<String, String>

Inline styles for the description text span.

extraWrapperAttrs(CheckboxProps props) → Map<String, String>

Extra wrapper attributes merged after data-state/data-disabled (e.g. data-variant/data-size); return an empty map for none.

labelTextStyles(CheckboxProps props) → Map<String, String>

Inline styles for the label text span.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

shouldRebuild(covariant Component newComponent) → bool

Implement this method to determine whether a rebuild can be skipped.

inherited

toString() → String

A string representation of this object.

inherited

wrapperClasses(CheckboxProps props) → String

Classes for the wrapper element (some themes append a disabled marker).

wrapperStyles(CheckboxProps props) → Map<String, String>

Inline styles for the wrapper element.

Operators

operator ==(Object other) → bool

The equality operator.
