pure is always there as prop I think

skipUpdate?: (prev: any, next: any) => boolean;
}

export const withTracker = (options: ReactiveFn | ReactiveOptions) => {
return (Component: React.ComponentType) => {
const getMeteorData = typeof options === 'function' ?
options :
options.getMeteorData;

const WithTracker = forwardRef((props, ref) => {
const data = useTracker('withTracker',
() => getMeteorData(props) || {});
return (
<Component ref={ref} {...props} {...data} />
);
});

const { pure = true } = options;
return pure ? memo(WithTracker) : WithTracker;
};
};
