+# Traccar Client Fork - Agent Specification
+
+This spec describes how to transform a fresh fork of [traccar/traccar-client](https://github.com/traccar/traccar-client) (Flutter) into a simplified, hardcoded tracking client. Apply all changes to the `main` branch.
+
+## Goal
+
+Create a minimal Traccar Client that:
+- Hard-codes all server/tracking settings (no user configuration)
+- Shows only a device ID and a tracking toggle in the UI
+- Removes access to settings, status, manual send, QR scanning, and password protection
+
+## Upstream Repository
+
+```
+https://github.com/traccar/traccar-client
+```
+
+The app is a Flutter project targeting iOS and Android from a single Dart codebase.
+
+---
+
+## 1. Configuration File: `lib/config.dart`
+
+Create a new file `lib/config.dart` with compile-time constants. This is the single source of truth for all hardcoded settings. A developer forking this project only needs to edit this file to reconfigure the app.
+
+```dart
+class AppConfig {
+  AppConfig._();
+
+  /// Traccar server URL
+  static const String serverUrl = 'https://c.track.rs';
+
+  /// Location accuracy: 'highest', 'high', 'medium', or 'low'
+  static const String accuracy = 'highest';
+
+  /// Location update interval in seconds
+  static const int intervalSeconds = 60;
+
+  /// Distance filter in meters (0 = disabled)
+  static const int distanceFilter = 0;
+
+  /// Whether to enable stop detection
+  static const bool stopDetection = false;
+
+  /// Whether to buffer locations when offline
+  static const bool buffer = true;
+
+  /// Fastest location update interval in seconds (Android)
+  static const int fastestIntervalSeconds = 30;
+}
+```
+
+All other modified files must read from `AppConfig` instead of using inline literals.
+
+---
+
+## 2. Hardcoded Settings (via `AppConfig`)
+
+These values are set in `lib/config.dart` and enforced at runtime:
+
+| Setting            | Constant                          | Default Value            |
+|--------------------|-----------------------------------|--------------------------|
+| Server URL         | `AppConfig.serverUrl`             | `https://c.track.rs`    |
+| Location Accuracy  | `AppConfig.accuracy`              | `highest`                |
+| Interval           | `AppConfig.intervalSeconds`       | `60`                     |
+| Distance Filter    | `AppConfig.distanceFilter`        | `0` (disabled)           |
+| Stop Detection     | `AppConfig.stopDetection`         | `false` (disabled)       |
+| Buffer             | `AppConfig.buffer`                | `true`                   |
+| Fastest Interval   | `AppConfig.fastestIntervalSeconds`| `30`                     |
+
+---
+
+## 3. File Changes
+
+### 3.1 `lib/preferences.dart`
+
+Add `import 'config.dart';` at the top.
+
+#### `migrate()` method
+After the existing migration logic and device ID generation, force-set values from `AppConfig`:
+
+```dart
+// After device ID generation
+await instance.setString(url, AppConfig.serverUrl);
+await instance.setString(accuracy, AppConfig.accuracy);
+await instance.setInt(interval, AppConfig.intervalSeconds);
+await instance.setInt(distance, AppConfig.distanceFilter);
+await instance.setBool(buffer, instance.getBool(buffer) ?? AppConfig.buffer);
+await instance.setBool(stopDetection, AppConfig.stopDetection);
+await instance.setInt(fastestInterval, instance.getInt(fastestInterval) ?? AppConfig.fastestIntervalSeconds);
+```
+
+#### `geolocationConfig()` method
+Replace dynamic preference reads with `AppConfig` references:
+
+- `isHighestAccuracy` = `AppConfig.accuracy == 'highest'`
+- `locationUpdateInterval` = `AppConfig.intervalSeconds * 1000` (but set to `0` in the config when highest accuracy)
+- `desiredAccuracy`: Use `DESIRED_ACCURACY_NAVIGATION` on iOS, `DESIRED_ACCURACY_HIGH` on Android (when highest)
+- `url`: `AppConfig.serverUrl` (passed through `_formatUrl`)
+- `distanceFilter`: `AppConfig.distanceFilter.toDouble()`
+- `locationUpdateInterval` (in config): `0` (when highest accuracy, for continuous tracking)
+- `disableElasticity`: `true`
+- `disableStopDetection`: `!AppConfig.stopDetection`
+- `pausesLocationUpdatesAutomatically`: `false` on iOS, `null` on Android
+- `fastestLocationUpdateInterval`: `0` when highest accuracy, else `AppConfig.fastestIntervalSeconds * 1000`
+
+### 3.2 `lib/main_screen.dart`
+
+**Complete rewrite.** Replace the entire file with a minimal screen containing:
+
+1. **AppBar** with title `'Traccar Client'`
+2. **Centered body** with two cards:
+   - **Device ID card**: Shows label "Device ID" and a `SelectableText` displaying the device ID in monospace bold (`headlineSmall`)
+   - **Tracking toggle card**: A `SwitchListTile` labeled "Continuous Tracking" with subtitle showing state ("Sending location updates" / "Location tracking disabled")
+3. **Tracking toggle behavior**:
+   - On: calls `bg.BackgroundGeolocation.start()` then checks battery optimizations
+   - Off: calls `bg.BackgroundGeolocation.stop()`
+   - Track `isMoving` state; set `activeTrackColor` to error color when `isMoving == false` (stationary warning)
+4. **State listeners**: Listen to `onEnabledChange` and `onMotionChange` from BackgroundGeolocation
+5. **Battery optimization dialog**: Keep the `_checkBatteryOptimizations` method that shows a dialog using `bg.DeviceSettings`
+
+**Remove entirely:**
+- Settings button/navigation
+- Status screen button/navigation
+- "Send Location" button
+- Password service import and usage
+- Any reference to `SettingsScreen` or `StatusScreen` navigation
+
+**Imports needed:** `flutter/material.dart`, `flutter/services.dart`, `traccar_client/main.dart` (for `messengerKey`), `traccar_client/preferences.dart`, `flutter_background_geolocation`, `l10n/app_localizations.dart`
+
+### 3.3 `lib/settings_screen.dart`
+
+**Complete rewrite.** Replace with a minimal read-only screen (not navigable from main UI, but kept for completeness):
+
+Add `import 'config.dart';` at the top.
+
+- Device ID display (read-only `ListTile`)
+- Continuous Tracking `SwitchListTile` (functional)
+- Read-only disabled `ListTile` entries displaying values from `AppConfig`:
+  - Server: `AppConfig.serverUrl`
+  - Location Accuracy: `AppConfig.accuracy`
+  - Distance: `AppConfig.distanceFilter` (show "Disabled" when 0)
+  - Interval: `'${AppConfig.intervalSeconds} seconds'`
+  - Stop Detection: `AppConfig.stopDetection` (show "Disabled"/"Enabled")
+
+### 3.4 `ios/Runner.xcodeproj/project.pbxproj`
+
+Find the build phase named `FlutterFire: "flutterfire upload-crashlytics-symbols"` and prepend `exit 0` to the shell script to skip it. This prevents `flutterfire: command not found` build failures.
+
+The `shellScript` value should start with:
+```
+\n#!/bin/bash\n# Skip Firebase Crashlytics for now\nexit 0\n
+```
+followed by the original script content (which will never execute).
+
+---
+
+## 4. Files NOT Modified
+
+These files remain unchanged from upstream:
+- `lib/main.dart` - App entry point, Firebase init, app links, rate dialog
+- `lib/geolocation_service.dart`
+- `lib/configuration_service.dart`
+- `lib/push_service.dart`
+- `lib/quick_actions.dart`
+- `lib/location_cache.dart`
+- `lib/status_screen.dart` - Kept in codebase but not navigable
+- `lib/password_service.dart` - Kept in codebase but unused
+- `lib/qr_code_screen.dart` - Kept in codebase but not navigable
+- `pubspec.yaml`
+- All localization files (`lib/l10n/`)
+- Android platform files
+
+---
+
+## 5. Verification Checklist
+
+After applying changes:
+
+1. `flutter pub get` succeeds
+2. `flutter build ios` succeeds (no flutterfire errors)
+3. `flutter build apk --release` succeeds
+4. App launches showing only device ID and tracking toggle
+5. No settings, status, or send location buttons visible
+6. Toggling tracking on starts background location reporting to `https://c.track.rs`
+7. Device ID is auto-generated (8-digit random number) and persists across launches
+8. Location updates use highest accuracy with 0 distance filter
+9. Stop detection is disabled (tracking never auto-pauses)
