Turn on location services without navigating to settings page ? Flutter Dart - dart

Question

We are migrating from to Flutter. We used this thread to Turn on location services without navigating to settings page
How can this be achieved in Flutter?
The current temporary code that navigates to settings:
Future _getCurrentLocation() async {
Position position;
try {
position = await Geolocator().getCurrentPosition(
desiredAccuracy: LocationAccuracy.bestForNavigation);
} on PlatformException catch(e){
print(e.code);
if(e.code =='PERMISSION_DISABLED'){
print('Opening settings');
await openLocationSetting();
try {
position = await Geolocator().getCurrentPosition(
desiredAccuracy: LocationAccuracy.bestForNavigation);
} on PlatformException catch(e){
print(e.code);
}
}
}
setState(() {
// _center = LatLng(currentLocation['latitude'], currentLocation['longitude']);
_center = LatLng(position.latitude, position.longitude);
});
}
Future openLocationSetting() async {
final AndroidIntent intent = new AndroidIntent(
action: 'android.settings.LOCATION_SOURCE_SETTINGS',
);
await intent.launch();
}

Add a map in the body of your screen
#override
Widget build(BuildContext context) {
return Scaffold(
body: Builder(
builder: (context) => Stack(
children: [
GoogleMap(
scrollGesturesEnabled: true,
tiltGesturesEnabled: true,
rotateGesturesEnabled: true,
mapToolbarEnabled: true,
mapType: MapType.normal,
onTap: _placeMarker,
onMapCreated: _onMapCreated,
markers: Set.from(myMarker),
initialCameraPosition: CameraPosition(
target: _center,
zoom: 5.0,
),
),
Padding(
padding: (EdgeInsets.symmetric(horizontal: 16, vertical: 40)),
child: Align(
alignment: Alignment.topRight,
child: Column(
children: [
CircleAvatar(
radius: 30,
child: IconButton(
onPressed: () {
navigate(context);
},
icon: Icon(
Icons.done,
color: Colors.white,
),
),
),
SizedBox(
height: 10,
),
CircleAvatar(
radius: 30,
child: IconButton(
onPressed: **getLocation**,
icon: Icon(
Icons.location_on,
color: Colors.white,
),
),
)
],
),
),
),
Padding(
padding: (EdgeInsets.symmetric(horizontal: 16, vertical: 40)),
child: Align(
alignment: Alignment.topLeft,
child: Column(
children: [
CircleAvatar(
radius: 30,
child: IconButton(
onPressed: () {
Navigator.pop(context);
},
icon: Icon(
Icons.chevron_left,
color: Colors.white,
),
),
),
SizedBox(
height: 10,
),
],
),
),
)
],
),
));
}
getLocation() async {
position = await Geolocator.getCurrentPosition(
desiredAccuracy: LocationAccuracy.high);
print(position);
mapController.animateCamera(CameraUpdate.newCameraPosition(CameraPosition(
target: LatLng(position.latitude, position.longitude),
zoom: 18,
tilt: 36)));
}
This code will initialize the Google maps in the home screen and if the location is turned of then an alert box will be popped up asking for the permission then it will be automatically turned on

Answer 2

You can use the location package, you just have to add the required permissions in your AndroidManifest.xml and Info.plist files, permission will be asked in a pop-up.
