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();
},
)
],
);
});
}
