-# apskel_pos_flutter_v2
+# Apskel POS Flutter
 
-A new Flutter project.
+Aplikasi Point of Sale (POS) berbasis Flutter untuk manajemen kasir restoran. Mendukung manajemen order, produk, meja, pelanggan, pembayaran, printer bluetooth/network, analitik, dan push notification via FCM.
 
-## Getting Started
+---
 
-This project is a starting point for a Flutter application.
+## Fitur Utama
 
-A few resources to get you started if this is your first Flutter project:
+- **Autentikasi** — Login dengan email & password, logout, session management
+- **Order Management** — Buat, kelola, dan proses order
+- **Produk & Kategori** — Manajemen menu dan kategori produk
+- **Meja** — Manajemen meja restoran
+- **Pelanggan** — Data pelanggan dan riwayat transaksi
+- **Checkout & Pembayaran** — Proses checkout dengan berbagai metode pembayaran
+- **Split Bill** — Pembagian tagihan
+- **Void & Refund** — Pembatalan dan pengembalian transaksi
+- **Printer** — Cetak struk via Bluetooth dan Network printer
+- **Analitik** — Dashboard, laporan penjualan, produk, kategori, payment method, profit/loss, inventory
+- **Sinkronisasi** — Sinkronisasi data offline/online
+- **Push Notification (FCM)** — Notifikasi real-time via Firebase Cloud Messaging

+## Arsitektur
+
+Project menggunakan **Clean Architecture** dengan 4 layer:
+
+```
+lib/
+├── application/        # BLoC — state management per fitur
+├── domain/             # Entity, repository interface, failure
+├── infrastructure/     # Implementasi repository, DTO, datasource
+├── presentation/       # UI — pages, components, router
+└── common/             # Shared utilities, DI modules, service, theme
+```
+
+### Struktur per Fitur
+
+```
+feature/
+├── application/
+│   └── feature_bloc.dart         # BLoC
+├── domain/
+│   ├── entities/                 # Domain model (freezed)
+│   ├── repositories/             # Interface repository
+│   └── failures/                 # Failure types

+    └── repositories/             # Implementasi repository
+```
+
+---
+
+## Setup & Menjalankan
+
+### Prasyarat
+
+- Flutter SDK `^3.8.1`
+- Dart SDK `^3.8.1`
+- Android SDK / Xcode (untuk iOS)
+- Firebase project yang sudah dikonfigurasi
+
+### Instalasi
+
+```bash
+# Clone repository
+git clone <repo-url>
+cd apskel-pos-flutter-v2
+
+# Install dependencies
+flutter pub get
+
+# Generate kode (freezed, injectable, auto_route, json_serializable)
+dart run build_runner build --delete-conflicting-outputs
+```
+
+### Menjalankan App
+
+```bash
+# Development
+flutter run
+
+# Release
+flutter run --release
+```
+
+App otomatis menggunakan environment `dev` saat debug dan `prod` saat release.
+
+---
+
+## Environment
+
+Konfigurasi environment ada di `lib/env.dart`:
+
+| Environment | Base URL | Database |
+|---|---|---|
+| `dev` | `https://api-pos.apskel.id` | `apskel_pos_dev.db` |
+| `prod` | `https://api-pos.apskel.id` | `apskel_pos_dev.db` |
+
+Environment dipilih otomatis di `main.dart`:
+
+```dart
+await configureDependencies(
+  kReleaseMode ? Environment.prod : Environment.dev,
+);
+```
+
+---
+
+## Dependency Injection
+
+DI menggunakan `get_it` + `injectable`. Semua service, repository, dan BLoC didaftarkan via annotation.
+
+### Modul DI
+
+| File | Isi |
+|---|---|
+| `di_firebase.dart` | `FirebaseMessaging`, `FlutterLocalNotificationsPlugin`, `DeviceInfoPlugin`, `PackageInfo` |
+| `di_dio.dart` | `Dio` HTTP client |
+| `di_shared_preferences.dart` | `SharedPreferences` |
+| `di_database.dart` | `DatabaseHelper` (SQLite) |
+| `di_auto_route.dart` | `AppRouter` |
+| `di_connectivity.dart` | `Connectivity` |
+
+Setelah menambah atau mengubah class yang menggunakan annotation injectable, jalankan:
+
+```bash
+dart run build_runner build --delete-conflicting-outputs
+```
+
+---
+
+## Firebase & FCM
+
+### Setup
+
+Firebase sudah dikonfigurasi di `android/app/google-services.json`. Inisialisasi dilakukan di `main.dart` sebelum app berjalan.
+
+### FCM Service
+
+`FcmService` (`lib/common/service/fcm_service.dart`) menangani:
+
+- Request permission notifikasi (Android 13+ / iOS)
+- Ambil dan log FCM token
+- Foreground notification via `flutter_local_notifications`
+- Background & terminated message handler
+- Subscribe/unsubscribe topic
+
+FCM token dikirim ke server saat login bersama device info.
+
+### Login Payload
+
+Saat login, app mengirim data berikut ke API:
+
+```json
+{
+  "email": "user@example.com",
+  "password": "secret",
+  "fcm_token": "dXj3k9...",
+  "device_id": "abc123",
+  "device_name": "Samsung Galaxy Tab S8",
+  "device_type": "tablet",
+  "platform": "android",
+  "app_version": "1.0.4+9",
+  "os_version": "Android 13 (SDK 33)"
+}
+```
+
+Nilai valid: `device_type` → `mobile | tablet | desktop`, `platform` → `android | ios | web`
+
+---
+
+## Printer
+
+Mendukung dua jenis printer:
+
+- **Bluetooth** — via `print_bluetooth_thermal`
+- **Network (LAN)** — via `flutter_esc_pos_network`
+
+---
+
+## Orientasi Layar
+
+App dikunci ke mode **landscape** (kiri & kanan) karena didesain untuk tablet POS.
+
+---
+
+## Catatan Development
+
+- Jangan edit `injection.config.dart` dan file `*.freezed.dart` / `*.g.dart` secara manual — file tersebut di-generate otomatis
+- Gunakan `log()` dari `dart:developer` untuk logging, bukan `print()`
+- `print()` dinonaktifkan di release mode
