feat(react-checkbox): add useCheckboxBase_unstable hook#35826
Merged
Conversation
Implements base state hook for Checkbox component as part of the experimental base hooks initiative. The base hook extracts pure component logic while omitting design props (shape, size). - CheckboxBaseProps: omits shape, size - CheckboxBaseState: omits shape, size - useCheckboxBase_unstable: handles checked/indeterminate state (controlled/uncontrolled), onChange callback, ARIA attributes, focus management (useFocusWithin), input ref management, indeterminate layout effect, label slot with htmlFor, slot structure useCheckbox_unstable now calls useCheckboxBase_unstable and adds shape+size-specific checkmark icons. All new types and hooks exported from package index.ts. Co-Authored-By: Claude Sonnet 4.6 <[email protected]>
