Hook does not respond to changes in arguments

[huan086]

Initally

const [state, setState] = useState(false);
useBeforeUnload(state);

Subsequently

setState(true);

Expected result After setState, I get the prompt when navigating away.

Actual result No prompt is shown when navigating away

Code changes that's needed Move declaration of handleBeforeunload inside of the function passed to useEffect. Update the dependencies of useEffect to [value].

[handleBeforeunload] argument is missing in the useEffect, to fix this
