Callback

Function called when long press is detected

useLongPress(callback [, options]): bindFn

Hook first parameter, callback, can be either function or null (if you want to disable the hook).

It is recommended (althought not neccessary) to keep callback memoized using useCallback because it is a direct dependency for memoized hook result.

const callback = useCallback(..., [...]);
const bind = useLongPress(callback, ...);

For more info about callback structure and it's parameters see callbacks.
