Unleash the Power of Location Tracking with FlutterLocation

FlutterLocation is a robust Flutter plugin that simplifies the process of obtaining a user's location on Android, iOS, web, and macOS. This plugin provides a comprehensive set of features, including permission management, location updates, and background mode support.

Getting Started:

To integrate FlutterLocation into your project, add the following dependency to your pubspec.yaml file:

dependencies:
  location: ^5.0.0

Requesting Location Permission:

Before accessing the user's location, you must request permission. To do this, use the requestPermission method:

import 'package:location/location.dart';

Location location = Location();
PermissionStatus permissionGranted = await location.requestPermission();

Checking Permission Status:

You can check the current permission status using the hasPermission method:

PermissionStatus permissionStatus = await location.hasPermission();

Enabling the Location Service:

If the Location Service is disabled on the user's device, you can request that they enable it:

bool serviceEnabled = await location.serviceEnabled();

if (!serviceEnabled) {
  bool serviceEnabled = await location.requestService();
}

Changing Location Settings:

You can customize the accuracy, interval, and distance filter for location requests:

bool changedSettings = await location.changeSettings(
  accuracy: LocationAccuracy.HIGH,
  interval: 1000,
  distanceFilter: 0
);

Getting Current Location:

To obtain a one-time location fix, use the getLocation method:

LocationData locationData = await location.getLocation();

Listening for Location Updates:

For continuous location updates, subscribe to the onLocationChanged stream:

location.onLocationChanged.listen((LocationData currentLocation) {
  // Use the current location
});

Background Mode:

On Android and iOS, you can enable location updates even when the app is in the background:

bool enabledBackgroundMode = await location.enableBackgroundMode();

Custom Permission Handling:

While the plugin attempts to handle permission requests automatically, you may want to manage them manually. For example:

PermissionStatus permissionStatus = await location.hasPermission();

if (permissionStatus == PermissionStatus.deniedForever) {
  // Show a dialog explaining the need for location permissions
} else {
  // Attempt to request permission again
}

Error Handling:

The plugin throws exceptions for common errors, such as:

  • SERVICE_DISABLED: Location Service is disabled.
  • PERMISSION_DENIED: Location permission denied.
  • PERMISSION_DENIED_FOREVER: Location permission denied forever.

Example:

try {
  LocationData locationData = await location.getLocation();
} on LocationServiceDisabledException {
  // Handle service disabled error
} on PermissionDeniedException {
  // Handle permission denied error
} on PermissionDeniedForeverException {
  // Handle permission denied forever error
}

Conclusion:

FlutterLocation provides comprehensive location tracking capabilities for Flutter applications on multiple platforms. With its easy-to-use API and customizable options, this plugin empowers developers to seamlessly integrate location-based features into their apps.
