Detect Mock Location is enabled or disabled in Flutter - flutter

Question

My question is that I am using flutter platform to develop an app for my client and I want that my developed app should be able to be detect mock location status from android phone settings so I can check whether the location is coming from gps provider or mock location app. And if mock location is enabled then my app should throw an error msg

i had the same problem and i fixed it by coding in java and implement in flutter project.
here is what i did:
1) add this to your Main_Activity in flutter project.
import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.os.Bundle;
import io.flutter.app.FlutterActivity;
import io.flutter.plugins.GeneratedPluginRegistrant;
import io.flutter.plugin.common.MethodCall;
import io.flutter.plugin.common.MethodChannel;
import io.flutter.plugin.common.MethodChannel.MethodCallHandler;
import io.flutter.plugin.common.MethodChannel.Result;
import android.content.ContextWrapper;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.BatteryManager;
import android.os.Build.VERSION;
import android.os.Build.VERSION_CODES;
import android.os.Bundle;
import android.provider.Settings;
import android.util.Log;
import java.util.List;
public class MainActivity extends FlutterActivity {
private static final String CHANNEL = "samples.flutter.io/location";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GeneratedPluginRegistrant.registerWith(this);
new MethodChannel(getFlutterView(), CHANNEL).setMethodCallHandler(
new MethodCallHandler() {
#Override
public void onMethodCall(MethodCall call, Result result) {
if (call.method.equals("getLocation")) {
boolean b = getMockLocation();
result.success(b);
} else {
result.notImplemented();
}
}
});
}
public static boolean isMockSettingsON(Context context) {
// returns true if mock location enabled, false if not enabled.
if (VERSION.SDK_INT >= VERSION_CODES.CUPCAKE) {
if (Settings.Secure.getString(context.getContentResolver(),
Settings.Secure.ALLOW_MOCK_LOCATION).equals("0"))
return false;
else
return true;
}
return false;
}
public static boolean areThereMockPermissionApps(Context context) {
int count = 0;
PackageManager pm = context.getPackageManager();
List<ApplicationInfo> packages =
pm.getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo applicationInfo : packages) {
try {
PackageInfo packageInfo = pm.getPackageInfo(applicationInfo.packageName,
PackageManager.GET_PERMISSIONS);
// Get Permissions
String[] requestedPermissions = packageInfo.requestedPermissions;
if (requestedPermissions != null) {
for (int i = 0; i < requestedPermissions.length; i++) {
if (requestedPermissions[i]
.equals("android.permission.ACCESS_MOCK_LOCATION")
&& !applicationInfo.packageName.equals(context.getPackageName())) {
count++;
}
}
}
} catch (PackageManager.NameNotFoundException e) {
Log.e("Got exception " , e.getMessage());
}
}
if (count > 0)
return true;
return false;
}
private boolean getMockLocation() {
boolean b ;
b= areThereMockPermissionApps(MainActivity.this);
return b;
}
}
2) use it in your flutter_dart Code like this:
static const platform = const MethodChannel('samples.flutter.io/location');
bool mocklocation = false;
Future<void> _getMockLocation() async {
bool b;
try {
final bool result = await platform.invokeMethod('getLocation');
b = result;
} on PlatformException catch (e) {
b = false;
}
mocklocation = b;
}
if (mocklocation == true) {
return showDialog(
barrierDismissible: false,
context: context,
builder: (BuildContext context) {
return WillPopScope(
onWillPop: (){},
child: AlertDialog(
title: Text('Location'),
content: Text('Your Location is fake'),
),
);
});
}

Barzan's answer is very good, there's also a Flutter package named trust_location, you can find it here.
You can use it as following to check mock location:
bool isMockLocation = await TrustLocation.isMockLocation;
So, I recommend to use it.
