function App() {
  const [values, setValues] = useState("Apartments")
  return (
    <RadioGroup value={values} onChange={setValues}>
      <VStack space="md">
        <Radio value="Apartments">

        </Radio>
      </VStack>
    </RadioGroup>
  )
}

function App() {
  const radioRef = useRef(null)
  const handleRadioChange = (e) => {
    e.preventDefault()
    const checkboxValue = radioRef.current.checked
  }
  return (
    <RadioGroup>
      <VStack space="md">
        <Radio value="Hotels" ref={radioRef} onChange={handleRadioChange}>
          <RadioIndicator mr="$2">
            <RadioIcon as={CircleIcon} />
          </RadioIndicator>
          <RadioLabel>Hotels</RadioLabel>

        <Radio
          value="Living quarters"
          ref={radioRef}
          onChange={handleRadioChange}
        >
          <RadioIndicator mr="$2">
            <RadioIcon as={CircleIcon} />

          <RadioLabel>Living quarters</RadioLabel>
        </Radio>
      </VStack>
    </RadioGroup>
  )
}

function RadioGroupExample() {
  const [values, setValues] = useState("1st")
  return (
    <RadioGroup value={values} onChange={setValues}>
      <VStack space="sm">
        <Radio value="1st">
          <RadioIndicator mr="$2">
            <RadioIcon as={CircleIcon} />
          </RadioIndicator>
          <RadioLabel>Label 1</RadioLabel>
        </Radio>
        <Radio value="2nd">
          <RadioIndicator mr="$2">
            <RadioIcon as={CircleIcon} />
          </RadioIndicator>
          <RadioLabel>Label 2</RadioLabel>
