How to Mock Location on Device

How to mock location on device?

It seems the only way to do is to use a mock location provider.

You have to enable mock locations in the development panel in your settings and add

   <uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /> 

to your manifest.

Now you can go in your code and create your own mock location provider and set the location of this provider.

How to detect mock location in flutter for ios and android

you can use TrustLocation

permissions:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

usage :

import 'package:trust_location/trust_location.dart';

/* Assuming in an async function */
/// query the current location.
LatLongPosition position = await TrustLocation.getLatLong;

/// check mock location on Android device.
bool isMockLocation = await TrustLocation.isMockLocation;

using steam:

// input seconds into parameter for getting location with repeating by timer.
// this example set to 5 seconds.
TrustLocation.start(5);

/// the stream getter where others can listen to.
TrustLocation.onChange.listen((values) =>
print('${values.latitude} ${values.longitude} ${values.isMockLocation}')
);

/// stop repeating by timer
TrustLocation.stop();

Example:

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:trust_location/trust_location.dart';

import 'package:location_permissions/location_permissions.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _latitude;
  String _longitude;
  bool _isMockLocation;

  /// initialize state.
  @override
  void initState() {
    super.initState();
    requestLocationPermission();
    // input seconds into parameter for getting location with repeating by timer.
    // this example set to 5 seconds.
    TrustLocation.start(5);
    getLocation();
  }

  /// get location method, use a try/catch PlatformException.
  Future<void> getLocation() async {
    try {
      TrustLocation.onChange.listen((values) => setState(() {
        _latitude = values.latitude;
        _longitude = values.longitude;
        _isMockLocation = values.isMockLocation;
      }));
} on PlatformException catch (e) {
  print('PlatformException $e');
}
}

  /// request location permission at runtime.
  void requestLocationPermission() async {
    PermissionStatus permission =
        await LocationPermissions().requestPermissions();
    print('permissions: $permission');
    }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Trust Location Plugin'),
        ),
        body: Padding(
          padding: const EdgeInsets.all(20.0),
          child: Center(
          child: Column(
        children: <Widget>[
          Text('Mock Location: $_isMockLocation'),
          Text('Latitude: $_latitude, Longitude: $_longitude'),
         ],
       )),
     ),
   ),
 );
}
}

How to emulate GPS location in the Android Emulator?

You can connect to the Emulator via Telnet. You then have a Emulator console that lets you enter certain data like geo fixes, network etc.

How to use the console is extensively explained here.
To connect to the console open a command line and type

telnet localhost 5554

You then can use the geo command to set a latitude, longitude and if needed altitude on the device that is passed to all programs using the gps location provider. See the link above for further instructions.

The specific command to run in the console is

geo fix <longitude value> <latitude value>

I found this site useful for finding a realistic lat/lng: http://itouchmap.com/latlong.html

If you need more then one coordinate you can use a kml file with a route as well it is a little bit described in this article. I can't find a better source at the moment.

How to set fake GPS location on IOS real device

Of course ios7 prohibits creating fake locations on real device.

For testing purpose there are two approches:

1) while device is connected to xcode, use the simulator and let it play a gpx track.

2) for real world testing, not connected to simu, one possibility is that your app, has a special modus built in, where you set it to "playback" mode. In that mode the app has to create the locations itself, using a timer of 1s, and creating a new CLLocation object.

3) A third possibility is described here:
