Answer 1

Use Geolocator and check the Position object's isMocked property.

Answer 2

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'),
],
)),
),
),
);
}
}

I think better to use safe_device. It's working on both Android and IOS
