The list Screen gets data on mount and that's it. If you want it to gets a new data every time the category name changes you have to add it to the useEffect dependencies like so.

  const categoryName = navigation.route.params.categoryName;
  useEffect(() => {
    getData();
  },[categoryName]);

Now every time categoryName changes getData gets called.

if you are using tabs just add unmountOnBlur: true, in the <Tab.Screen/> of the screen you are in
