how to pass arguments to refetch fuction of useQuerry

I have function in my react native app which gets user latitude and longitude. Executing this function using useEffect. If i get location I want to fetch the data based on location( latitude and longitude ) otherwise want to show fallback component. i disable the query to run automatically by making enable=false. Now how should I pass the location with refetch function to fetch the data.

that's not how it works: https://tkdodo.eu/blog/react-query-fa-qs#how-can-i-pass-parameters-to-refetch

So what could be better approach instead of storing location in a state. As useEffect will run every time when components mount and lat long update will cause refetch.

not sure what useEffect has to do here, not even sure what you are trying to achieve. Can you please describe your problem without jumping to conclusions like "executing in useEffect" or "passing params to refetch". you're likely going down the wrong path

const baseUrl = 'https://api.aladhan.com/v1/timings' 

export default function Home() {
  
  const insets = useSafeAreaInsets()
  const [location, setLocation] = useState<{} | null >(null)

  const fetchPrayerTime = async ()=> {
    const currentDay = new Date().getDate()
    const currentMonth = new Date().getMonth() + 1
    const currentYear = new Date().getFullYear()
    const today = `${currentDay}-${currentMonth}-${currentYear}`
  
    try {
      const response = await axios.get(`${baseUrl}/${today}?latitude=${location?.lat}&longitude=${location?.lon}`)
      return response?.data
    } catch (error) {
      console.log('error', error)
    }
  }

  const {data, isLoading, isError, refetch} = useQuery({
    queryKey:['fetchPrayerTime', location?.lat, location?.lon], 
    queryFn:fetchPrayerTime, 
    enabled:false
  })

  useEffect(() => {
    (async () => {
      let { status } = await Location.requestForegroundPermissionsAsync();
      if (status !== 'granted') {
        console.log('Permission to access location was denied');
      }
      let loca = await Location.getCurrentPositionAsync({});
      setLocation({lat:loca?.coords?.latitude, lon:loca?.coords?.longitude})
      if (location) {
        refetch()
      }
    })();
  }, []);

sir here in this component, I am asking user location permission, inside useEffect, so based on status I want to fetch data. as of now I put the location in a state after usr granted permission. My url endpoint requires latitude and longitude.

Location.requestForegroundPermissionsAsync can be a query too since it's async, and then you can just compose dependent queries

nice, an example will be perfect sir, please
