Flutter geolocator permissions
I'm late but it can be useful for other developers.
bool serviceEnabled;
LocationPermission permission;
// Test if location services are enabled.
serviceEnabled = await Geolocator.isLocationServiceEnabled();
permission = await Geolocator.checkPermission();
if (permission == LocationPermission.denied) {
permission = await Geolocator.requestPermission();
if (permission == LocationPermission.denied) {
Get.snackbar('', 'Location Permission Denied');
// Permissions are denied, next time you could try
// requesting permissions again (this is also where
// Android's shouldShowRequestPermissionRationale
// returned true. According to Android guidelines
// your App should show an explanatory UI now.
return Future.error('Location permissions are denied');
}
}
if (permission == LocationPermission.deniedForever) {
// Permissions are denied forever, handle appropriately.
return Future.error(
'Location permissions are permanently denied, we cannot request permissions.');
}
return Geolocator.getCurrentPosition(
desiredAccuracy: LocationAccuracy.high);
Just remove the isServiceEnabled
check, when you request permission, it will automatically ask the user to enable the device location service.

My code is:
class _LoadingScreenState extends State<LoadingScreen> { void getLocation() async { Position position = await Geolocator.getCurrentPosition( desiredAccuracy: LocationAccuracy.low); print(position); }
I added to the Android manifest the following:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
Android emulator, GPS is on.
After trying to access geolocation I receive an error:
E/flutter ( 5034): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: User denied permissions to access the device's location. E/flutter ( 5034): #0 MethodChannelGeolocator.getCurrentPosition (package:geolocator_platform_interface/src/implementations/method_channel_geolocator.dart:127:7) E/flutter ( 5034): <asynchronous suspension> E/flutter ( 5034): #1 _LoadingScreenState.getLocation (package:clima/screens/loading_screen.dart:11:25) E/flutter ( 5034): <asynchronous suspension>
In
Settings - Security & location - Privacy - Location - App level permissions
my app's permission is off.After turning it on I receive a request:
Why is it happening?
Here https://pub.dev/packages/geolocator it is stated that
The geolocator will automatically try to request permissions when you try to acquire a location through the getCurrentPosition or getPositionStream methods. We do however provide methods that will allow you to manually handle requesting permissions.
Aren't the permissions supposed to be set as a result of the selection in the permission request?
I have almost the same problem with iOS: In the Settings - Privacy - Location Services - my app permission is set to While Using. After trying to access geolocations I receive to dialog window but an error:
[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: User denied permissions to access the device's location. #0 MethodChannelGeolocator.getCurrentPosition (package:geolocator_platform_interface/src/implementations/method_channel_geolocator.dart:127:7) #1 _LoadingScreenState.getLocation (package:clima/screens/loading_screen.dart:11:25)
but why?

Mariano Zorrilla over 2 yearsYou need to request the actual pop up permission to the user. It's not enough with adding the permission over the Manifest. Android never auto request permissions, is a manual process (or, sometimes libraries will request for you to avoid doing the code)
-
Peter Koltai over 2 yearsI suggest using permission_handler package to get user's permission.
