type close = () => void;

snapToPosition

Snaps the bottom drawer to given position

type snapToPosition = (
  sheetHeight: number,
  config?: {
    resetLastPosition?: boolean;
  },
) => void;

type snapToIndex = (index: number) => void;

NOTE: This method is only accessible when enableSnapping is set to true.
