traccar_client_sdk 0.0.24

Flutter plugin for background location tracking. Wraps the Traccar Client SDK for Android and iOS.

traccar_client_sdk

Flutter plugin for background location tracking. Sends position updates over a simple HTTP GET protocol - works with Traccar and any compatible server. Wraps the Traccar Client SDK for Android and iOS - see the main repository for architecture, reliability, and configuration details.

Requires Android API 24+ and iOS 15+.

Usage

import 'package:traccar_client_sdk/traccar_client_sdk.dart';

final tracker = TraccarClientSdk();

await tracker.start(Config(
  serverUrl: 'https://demo.traccar.org',
  deviceId: '123456',
));

await tracker.stop();

API

• start(Config) - begin tracking. Returns false if required Android permissions were denied.
• stop() - stop tracking and clear saved config.
• requestPosition(Config) - one-off fix and upload, independent of start/stop.
• isTracking() - query current state.
• getLogs() - recent diagnostic entries (time ms, message).
• clearLogs() - clear the diagnostic store.

Configuration

Config accepts a LocationConfig (accuracy, distanceMeters, intervalSeconds, angleDegrees, stopDetection, stopTimeoutSeconds, stationaryRadiusMeters), a Boolean buffer (real-time-only when false), Android-only wakeLock, and a NotificationConfig for the Android foreground-service text. See the main repo for details and defaults.

Permissions

The plugin requests location, notification (Android 13+), and activity recognition (Android 10+) permissions at runtime via a transparent activity. On first start it also opens the Ignore Battery Optimization settings screen once.

On iOS, add these keys to your app's Info.plist:

• NSLocationAlwaysAndWhenInUseUsageDescription
• NSLocationWhenInUseUsageDescription
• NSMotionUsageDescription

and enable the Location updates background mode in your target capabilities.

If you set heartbeatIntervalSeconds, also add fetch to UIBackgroundModes and add org.traccar.client.heartbeat to BGTaskSchedulerPermittedIdentifiers. iOS schedules the wake at its discretion.
