Try this in your ScreenB. const screenALoading = props.navigation.state.params.loading; – Anurodh Singh Mar 10 '20 at 17:15 ,Since I only want to do further navigations to ScreenB, if loading changes, it's important to add loading as a dependency of useEffect.,On Screen A, there is a value to keep track of loading of a GraphQL mutation. I want to pass that loading value to Screen B. My problem is that when I try to pass that value as a param to Screen B using navigation.navigate(ScreenB, { loading }), the value of loading does not update - it always remains as whatever the value was at the moment that navigation.navigate was invoked.

In order to update loading on Screen B after having switched from Screen A, I call navigation.navigate again with the updated value but only after having switched to ScreenB.

const [navigatedToScreenB, toggleNavigatedToScreenB] = useState<boolean>(false);

useEffect(() => {
  if(navigatedToScreenB) {
   navigation.navigate(ScreenB, { loading });
  }
}, [loading])
