Types

WheelData

interface WheelData {
  option?: string;

Prop	Type	Default	Description
option	string	''	String to be rendered inside an option.
image	ImageProps	-	Image to be rendered inside an option. It is configured through ImageProps
style	StyleType	-	Styles for option. It is configured through StyleType
optionSize	number	1	Integer that sets the size of the option measured in roulette pieces. For example: if data provides 2 options A and B, and you set A's optionSize to 2, B's optionSize to 1, the roulette will render 3 pieces: 2 corresponding to A and 1 corresponding to B. Therefore, A will appear to be twice as big as B.

offsetX	number	0	Image offset in its X axis
offsetY	number	0	Image offset in its Y axis
sizeMultiplier	number	1	A value of 1 means image height is calculated as 200px * sizeMultiplier and width will be calculated to keep aspect ratio.
landscape	boolean	false	If true, image will be rotated 90 degrees so as to render in a landscape orientation.

interface PointerProps {
  src?: string; // Optional

const data = [
  { option: '0' },
  { option: '1' },
  { option: '2' },
]

export default () => {
  const [mustSpin, setMustSpin] = useState(false);
  const [prizeNumber, setPrizeNumber] = useState(0);

  const handleSpinClick = () => {
    const newPrizeNumber = Math.floor(Math.random() * data.length)
    setPrizeNumber(newPrizeNumber)
    setMustSpin(true)
  }

  return (
    <>
      <Wheel
        mustStartSpinning={mustSpin}
        prizeNumber={prizeNumber}
        data={data}

        onStopSpinning={() => {
          setMustSpin(false);
