import { Button, Text, Group } from '@tidbcloud/uikit'
 
function Demo() {
  const { supported, open } = useEyeDropper()
  const [color, setColor] = useState('')
 
  const handlePick = async () => {
    const result = await open()
    if (result) {
      setColor(result.sRGBHex)
    }
  }
 
  if (!supported) {
    return <Text>EyeDropper API is not supported in this browser</Text>
  }
 
  return (
    <Group>
      <Button onClick={handlePick}>Pick color</Button>
      {color && (
        <>
          <Text>Picked color: {color}</Text>
          <div style={{ width: 30, height: 30, backgroundColor: color }} />
        </>
