Flutterlocation: "getLocation()" never returns

Created on 18 Apr 2019  ·  54Comments  ·  Source: Lyokone/flutterlocation

(First of all, thanks for your hardwork at this library)

Describe the bug
I am calling this method before calling "runApp(MyApp())" in my main method. I need this because my app needs a current known location at its very first frame:

_getLastKnownLocation() async {
  print("STARTING LOCATION SERVICE");
  var location = Location();
  location.changeSettings(accuracy: LocationAccuracy.POWERSAVE);
  if (!await location.hasPermission()) {
    await location.requestPermission();
  } 

  InMemoryDatabase.lastKnownLocation = await location.getLocation();
}

The call gets stuck on the last line of this method, never returning a proper position.

I am using library version 2.3.5 with flutter 1.2.1

Expected behavior
The method should return a position.

Tested on:

  • Android, 8.1.0 Motorola Moto G5S (real device)

I'm doing this, to avoid this bug

    var location = Location();
    location.changeSettings(accuracy: LocationAccuracy.LOW);

    LocationData position;

    bool hasPermission = await location.hasPermission() && await location.serviceEnabled();

    if (Platform.isAndroid) {
      if (!hasPermission) {
        hasPermission = await location.requestPermission() && await location.requestService();
      }
    } 

    if (hasPermission) {
      position = await location.getLocation().catchError(
        (e) => print("Unable to find your position."), 
        test: (e) => e is PlatformException
      ).catchError((e) => print("$e"));
    }

Hey ! I'll look into this over the weekend. Don't hesitate to use the authorisation process from the sample app in the mean time :)

Hi @Lyokone ,

Thanks for this wonderful plugin.
I am also facing the same issue.

Please fix or suggest or suggest an alternate meanwhile.

Thanks,

Hey ! Spent most of my time on the background location feature this weekend, so wasn't able to look into this. A simple workaround would be to use onLocationChanged() and to remove the listener once you get the first result.
Sorry for the delay in fixing this :/

I've tested your sollution with await location.onLocationChanged().first and still blocking =(

Thanks for the great work, unfortunately having the same problem.

I upgraded from v1.2.0 which worked fine to v2.3.5 recently and started having this problem. Tried each version between 2.0.0 and 2.3.5 and also tried location.onLocationChanged().first but always get the same problem. Also downgrading below v2.0.0 isn't possible for my app now as I am building for iOS and android and version constraints keep me from going back.

Hey !

This is really strange since I'm having no problem on my end during testing and using the plugin in projects. Have you updated everything ? Can you launch adb logcat to see if you can get any other logs ?

Thanks for any help you can provide, here's what I hope is near the beginning of the relevant logs using adb logcat from when I start using getLocation:

Any news? I'm facing the same issue.

Hey, I've been unable to reproduce this error on my end for now. Is the
sample project working correctly for you ?

I flashed a new custom ROM (Android Pie) on my phone, and now it works, and neither do I cannot reproduce the bug now. I'm going to try to reproduce it these days.

By the way, could it be a MIUI related issue?

Happy to know 😁
Can any other participant of the thread tell if they are using custom ROMs
?

So a lot of different devices, Pixels especially should be fine. Is the sample app working properly for you ? Maybe the plugin isn't returning a proper error of something you would be missing.

The app is not crashing but it is giving null on getLocation()
i tried it in galaxy j5

`LocationData _currentLocation;

Location _location;

Future getLoc() async {
_currentLocation = await _location.getLocation();

try {
  return _currentLocation.longitude;
} catch (e) {
  print("Error");
}
return 0.0;

@sarimk80 Location _location = Location()

veetaw picture veetaw on 4 May 2019

Just to give another update on this issue, I took care of the problems by handling permissions another way before calling _location.getLocation();

Seems like the problem I was having was about handling permissions properly? Sorry I have not ran into the problem in the example app, as far as I can recall it worked fine.

VinceERS picture VinceERS on 7 May 2019

I am also having this issue. Requesting permissions first, then on confirm of permissions, calling getLocation()

NilsBacke picture NilsBacke on 10 May 2019

I'm having the same issue here. When I call _location= await Location().getLocation(); it show me a dialog about enabling the device location and it enable the location, but the function never return.

pedromassango picture pedromassango on 13 May 2019

Call the future method in future builder this method work for me

` LocationData _currentLocation;

Location _location = Location();

Future getLoc() async {
_currentLocation = await _location.getLocation();

try {
  final coordinates = new Coordinates(
      _currentLocation.latitude, _currentLocation.longitude);
  var addresses =
      await Geocoder.local.findAddressesFromCoordinates(coordinates);
  var first = addresses.first;
  return first.locality;
} catch (e) { 
}
return "Earth";

}`

Try calling future with Future Builder

`body: FutureBuilder(

        future: getLoc(),

        builder: (BuildContext context, AsyncSnapshot snapshot_loc) {

          print(snapshot_loc.data);
          if (!snapshot_loc.hasData) {
            return Center(
              child: CircularProgressIndicator(),
            );
          } else {
         print(snapshot_loc.data)

        }`

I need to load my data out of a widget. I've tried to load using Future but it ins't work.

I figured out why it was not working for me. requestPermission was not getting called. After debugging it I found another plugin (device_calendar) was blindly returning true in their permissions handler even though it was for a different permission. Thus flutter was not calling the handler for location.

I don't know that you can isolate your request. In the flutter engine it looks like it exits the loop after the first plugin that returns true. Thus if you have another plugin requesting the same permission and they get notified before you your plugin will not get called. Look here:
https://github.com/flutter/engine/blob/45f69ac471b47e95dfeef36e5e81597b05ed19f5/shell/platform/android/io/flutter/app/FlutterPluginRegistry.java

`
@Override
public boolean onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {

    for (RequestPermissionsResultListener listener : mRequestPermissionsResultListeners) {

        if (listener.onRequestPermissionsResult(requestCode, permissions, grantResults)) {

            return true;

        }

    }

    return false;
}

Same issue, getting
PlatformException (PlatformException(ERROR, Failed to get location., null))
on

Dart 2.3.0

Karlheinzniebuhr picture Karlheinzniebuhr on 11 Jun 2019

Thanks @xascis. I had the same issue and discovered that it was my power setting that made getLocation() requests unresponsive. I had accuracy set to LocationAccuracy.POWERSAVE, and setting it to LocationAccuracy.LOW solved the issue for me.

Info about PRIORITY_NO_POWER setting on android: https://developers.google.com/android/reference/com/google/android/gms/location/LocationRequest

Davestring picture Davestring on 19 Apr 2020

For those who still having this issue I'm using this workaround:

  1. Use another package to check and ask for permission
  2. If permission granted then use this package

This works and is what I'm currently using in prodution. Let me know if this helps you in any way.

@pedromassango also have this solution in place for several Flutter apps but it's extremely poor. Seeing the issue on our iOS apps for Reach-Native.

@Lyokone do you have plans to use another package for permission requests?

Still the same issue I think I will use flutter-geolocator https://pub.dev/packages/geolocator
