Features

  • Keyboard support for actions.
  • Support for hover, focus and active states.

Accessibility

We have outlined the various features that ensure the Radio component is accessible to all users, including those with disabilities. These features help ensure that your application is inclusive and meets accessibility standards. Adheres to the WAI-ARIA design pattern.

Keyboard

  • Tab: Moves focus to the next focusable element.
  • Shift + Tab: Moves focus to the previous focusable element.
  • Space: To check or uncheck focused radio.

Screen Reader

  • VoiceOver: When the radio is focused, the screen reader will announce it's a radio and it's current state (check or uncheck) and it's label.

Focus Management

  • The onFocus and onBlur props manage focus states and provide visual cues to users. This is especially important for users who rely on keyboard navigation.

States

  • In error state, aria-invalid will be passed to indicate that the radio input has an error, and providing support for an aria-errormessage to describe the error in more detail.
  • In disabled state, aria-hidden will be passed to make radio input not focusable.
  • In required state, aria-required will be passed to indicate that the radio input is required.

Props

Radio component is created using Pressable component from react-native. It extends all the props supported by React Native Pressable.

return (
<RadioGroup value={values} onChange={setValues}>
<VStack space="sm">
<Radio value="Eng">
<RadioIndicator>
<RadioIcon as={CircleIcon} />
</RadioIndicator>

e.preventDefault()
const checkboxValue = radioRef.current.checked
}
return (
<RadioGroup>
<VStack space="md">
<Radio value="Hotels" ref={radioRef} onChange={handleRadioChange}>
<RadioIndicator>
