Answer 1

getLocation() async {
Location location = Location();
bool _serviceEnabled;
PermissionStatus _permissionGranted;
LocationData _locationData;
_serviceEnabled = await location.serviceEnabled();
if (!_serviceEnabled) {
_serviceEnabled = await location.requestService();
if (!_serviceEnabled) {
return;
}
}
_permissionGranted = await location.hasPermission();
if (_permissionGranted == PermissionStatus.denied) {
_permissionGranted = await location.requestPermission();
if (_permissionGranted != PermissionStatus.granted) {
return;
}
}
_locationData = await location.getLocation();
print(_locationData.longitude)
}

Answer 2

i solved the problem by create a custom dialog like the image i attached
so if the premission is denied, i will show this dialog
Future<bool> showAlertDialog({
required BuildContext context,
}) async {
if (!Platform.isIOS) {
return await showDialog(
context: context,
builder: (context) => AlertDialog(
title: const Text('Location Services Disabled'),
content: const Text('You need to enable Location Services in Setting'),
actions: <Widget>[
TextButton(
child: const Text('Cancel'),
onPressed: () => Navigator.of(context).pop(false),
),
TextButton(
child: const Text('Setting'),
onPressed: () {
openAppSettings();
Navigator.of(context).pop(false);
},
),
],
),
);
}
// todo : showDialog for ios
return await showCupertinoDialog(
context: context,
builder: (context) => CupertinoAlertDialog(
title: const Text('Location Services Disabled'),
content: const Text('You need to enable location services in setting'),
actions: <Widget>[
CupertinoDialogAction(
child: const Text('Cancel'),
onPressed: () => Navigator.of(context).pop(false),
),
CupertinoDialogAction(
child: const Text('Setting'),
onPressed: () {
openAppSettings();
Navigator.of(context).pop(false);
},
),
],
),
);
}
