Just subscribe to "onLocationChanged" Stream like in the example.

_location.onLocationChanged().listen((Map<String,double> result) {
          var latitude = result["latitude"]; //This is called always when the location updates
          var longitude = result["longitude"];
        });

For showing a popup when the user has no location enabled use this: 

try {
  currentLocation = await location.getLocation;
} on PlatformException {
await showDialog<dynamic>(
              context: context,
              builder: (context) {
                return AlertDialog(
                  title: Text("No Location"),
                  content: Text(
                      "Please allow this App to use Location or turn on your GPS."),
                  actions: <Widget>[
                    FlatButton(
                      child: Text(
                        "Ok"
                      ),
                      onPressed: () {
                        Navigator.of(context).pop();
                      },
                    )
                  ],
                );
              });
}
