🔄 TelurKu - Firebase Real-Time Sensor Integration FINAL

📊 Implementasi Lengkap

Semua fitur siap untuk real-time monitoring telur dari Firebase sensors!

✅ Yang Sudah Diimplementasikan:

1. KandangProvider - Sensor Listener

// Sensor Real-time Listeners
int _infra1Value = 0;    // Nilai telur dari infra1
int _infra2Value = 0;    // Nilai telur dari infra2

int get infra1Value => _infra1Value;
int get infra2Value => _infra2Value;

// Listen ke 'data' folder semua waktu
void listenToSensors() {
  _sensorSubscription = _database.ref('data').onValue.listen((event) {
    if (event.snapshot.exists) {
      final data = Map<dynamic, dynamic>.from(event.snapshot.value as Map);
      _infra1Value = data['infra1'] ?? 0;
      _infra2Value = data['infra2'] ?? 0;
      notifyListeners(); // UI terupdate otomatis!
    }
  });
}

2. Kandang Model - Support infraPath

class Kandang {
  final String id;
  final String nama;
  final int jumlahAyam;
  final DateTime dibuat;
  final String? infraPath;  // ← Optional path ke sensor
}

3. Dashboard - Tampil Data Real-Time

• Total Telur Hari Ini: infra1Value + infra2Value
• Status Kandang 1: infra1Value
• Status Kandang 2: infra2Value
• Auto-update tanpa perlu refresh!

🚀 Cara Kerja

Flow Data:

Firebase Database (data/infra1: 59, data/infra2: 78)
         ↓
KandangProvider.listenToSensors()
         ↓
Update _infra1Value & _infra2Value
         ↓
notifyListeners() — Trigger UI rebuild
         ↓
Dashboard tampil telur real-time ✨

Integrasi Sensor:

Kandang1 (index 0) ←→ infra1 (Firebase data/infra1)
Kandang2 (index 1) ←→ infra2 (Firebase data/infra2)

---

📲 Setup Firebase

1. Pastikan Data Ada di Firebase Console:

your_project/
├── data/
│   ├── infra1: 59    ← Sensor telur kandang 1
│   ├── infra2: 78    ← Sensor telur kandang 2
│   └── infraX: <value>

2. Buat 2 Kandang di Aplikasi:

Kandang Pertama:

• Nama: "Kandang1" (atau nama apapun)
• Jumlah Ayam: 50
• Firebase Path (optional): data/infra1

Kandang Kedua:

• Nama: "Kandang2"
• Jumlah Ayam: 48
• Firebase Path (optional): data/infra2

3. Test Sensor Real-Time:

1. Buka Dashboard di app
2. Lihat "Status Kandang" menampilkan telur
3. Update nilai di Firebase Console
4. Dashboard auto-update dalam 1-2 detik ⚡

🔧 Lifecycle

Saat User Login:

initializeWithUser(userId)
  ├─ Load kandang dari Firebase
  ├─ Setup kandang listener
  └─ Call listenToSensors() ← Mulai listen sensor

Saat Dashboard Dibuka:

Dashboard build()
  └─ Watch KandangProvider
     ├─ Ambil infra1Value
     ├─ Ambil infra2Value
     └─ Update UI (notifyListeners() trigger rebuild)

Saat User Logout:

clearData()
  ├─ Cancel kandang listener
  ├─ Cancel sensor listener ← Berhenti listen
  └─ Reset semua values ke 0

---

📝 Key Methods

Di KandangProvider:

// Mulai listening ke sensor
void listenToSensors() {
  _database.ref('data').onValue.listen((event) {
    _infra1Value = data['infra1'] ?? 0;
    _infra2Value = data['infra2'] ?? 0;
    notifyListeners();
  });
}

// Setter kandang tetap support infraPath
void addKandang(String nama, int jumlahAyam, {String? infraPath})

void updateKandang(String id, String nama, int jumlahAyam, {String? infraPath})

// Cleanup saat logout
Future<void> clearData() {
  _sensorSubscription?.cancel();
  _infra1Value = 0;
  _infra2Value = 0;
}

🎯 Mapping Kandang ↔ Sensor

Kandang	Index	Sensor	Path	Property
Kandang1	0	infra1	data/infra1	infra1Value
Kandang2	1	infra2	data/infra2	infra2Value

---

🔍 Dashboard Display

Total Telur Hari Ini:

kandangProvider.infra1Value + kandangProvider.infra2Value
= 59 + 78
= 137 🥚

Status Kandang:

Kandang1
├─ 50 ekor ayam
└─ 59 Telur (dari infra1) ← Real-time!

Kandang2
├─ 48 ekor ayam
└─ 78 Telur (dari infra2) ← Real-time!

⚙️ Firebase Rules

Pastikan rules allow read:

{
  "rules": {
    "data": {
      ".read": true,
      ".write": "auth != null"
    }
  }
}

---

🧪 Testing

Manual Test:

1. Running app
2. Lihat Dashboard → Total Telur = sum(infra1, infra2)
3. Edit Firebase: infra1 dari 59 → 100
4. Dashboard → Total berubah ke 178 secara otomatis!

Debug Log:

// Di KandangProvider
print('infra1Value: $_infra1Value');
print('infra2Value: $_infra2Value');
print('Total: ${_infra1Value + _infra2Value}');

📋 File Yang Berubah

lib/
├── models/
│   └── kandang_model.dart          ✅ Added infraPath field
├── providers/
│   └── kandang_provider.dart       ✅ Added sensor listeners (MAIN!)
│       ├─ _infra1Value, _infra2Value
│       ├─ listenToSensors()
│       ├─ initializeWithUser() calls listenToSensors()
│       └─ dispose() cancels listener
└── screens/
    └── dashboard_page.dart         ✅ Updated untuk tampil sensor values
        ├─ Total: infra1Value + infra2Value
        └─ Per kandang: index-based (0→infra1, 1→infra2)
