Fast Refresh is not working when I add the DeviceEventEmitter.addListener inside useEffect

[GabrielMobileQD]

Issue

I was using normally the Fast Refresh of the React Native. But when I installed the "react-native-settings" and added the code below:

useEffect(() => {
        DeviceEventEmitter.addListener(
            RNSettings.GPS_PROVIDER_EVENT,
            _handleGPSProviderEvent,
        );
        return () => {
            DeviceEventEmitter.removeAllListeners();
        };
    }, []);
  const _handleGPSProviderEvent = () => {
        if ([RNSettings.LOCATION_SETTING] === RNSettings.DISABLED) {
            console.log('Location was disabled');
        }
    };

To set the listener and check when the location is enabled or disabled by the user, the Fast Refresh, out of the blue, stopped working. But when I comment this code, the Fast Refresh works again. How could I use this code with the Fast Refresh working?

Anyone found the solution for this problem? It's happening with me too

Please replace your code with this.

useEffect(() => {
       let listner = DeviceEventEmitter.addListener(
            RNSettings.GPS_PROVIDER_EVENT,
            _handleGPSProviderEvent,
        );
        return () => {
            listner.remove();
        };
    }, []);
