I have a <MapView /> next to some position: absolute Views with Text in them. In the MapView, I have a <Circle /> within it to mark an area within the map. I have information like the user’s coordinates on the overlayed text, as well as if the user is within the radius of the circle area on the map.

I want to able to change the text being overlayed on top of the MapView without forcing a redraw of the map. Whenever the text changes, the map redraws itself which resets the user’s zoom and makes it disappear momentarily.

The text/view components are not within each other and are side by side for hierarchy.

The Location of the player is drawn on the MapView component with showUserLocation={true}. The actual coordinates are given to the Text components to display to the user with a Location.watchPositionAsync()

const myComponent = () => {
  const [location, setLocation] = useState(null);
  const [circle, setCircle] = useState({
    radius: 5,
    latitude: 0,
    longitude: 0,
  });

  // subscription to the users location
  useEffect(() => {
    subscription = await Location.watchPositionAsync(
      callback: (newLocation) => {
        setLocation(newLocation)
      }
    )
  }

  const isInCircleRadius() => {
    // return true/false based on if user is within the radius of the MapView Circle
  }

  return (
    <>
      <MapView 
        style={{ /* fullscreen all that stuff */ }}
        showUserLocation={true}>
          <Circle radius={circle.radius} center={circle.latitude, circle.longitude} />
      </MapView>
      <View>
        // Text changing here causes the MapView to redraw as well, even though this is just 
        // position: absolute and beside the MapView component
        <Text>{location.latitude} {location.longitude} {isInCircleRadius(location)}
      </View>
    </>
  )

}

I tried making the MapView into its own component and calling it within a parent component to hold the text and map component.

I tried making a local Location variable so only the Text component reads TextSpecificLocation and the MapView can use MapSpecificLocation even though they have the exact same data. Just to make it so they don’t rely on the same variable.
