🚀 Langkah Setup
1️⃣ Update Server URL (CRITICAL!)
File: lib/services/classification_service.dart line 7
// SEBELUM:
static const String _baseUrl = 'http://10.0.2.2:8000/api/classification';
// UBAH KE SESUAI ENVIRONMENT ANDA:
// Emulator Android: http://10.0.2.2:8000/api/classification
// Device Fisik: http://192.168.x.x:8000/api/classification (ganti dengan IP komputer)
// iOS Emulator: http://127.0.0.1:8000/api/classification
Cari IP komputer:
# Windows
ipconfig
# Mac/Linux
ifconfig
2️⃣ Install Dependencies
cd "d:\PROJECT TA\mobile_TA\padi_app"
flutter pub get
3️⃣ Run Server (3 Terminal)
Terminal 1 - Python API:
cd "d:\PROJECT TA\rice leaf diseases dataset"
python api_server.py
Terminal 2 - Laravel:
cd "d:\PROJECT TA\web_TA"
php artisan serve
Terminal 3 - Flutter:
cd "d:\PROJECT TA\mobile_TA\padi_app"
flutter run
4️⃣ Test
- App terbuka
- Navigate ke classification screen
- Pilih/ambil foto
- Tap "Klasifikasi Sekarang"
- Lihat hasil dengan confidence score, gejala, dan treatment

⚙️ Configuration Checklist
Sebelum jalankan app, pastikan:
-
Update API URL di
classification_service.dart- Sesuaikan dengan environment (emulator/device fisik)
- Cek IP komputer dengan
ipconfig
-
Install Flutter dependencies
flutter pub get -
Python API Server berjalan
cd rice_leaf_diseases_dataset python api_server.py -
Laravel Server berjalan
cd web_TA php artisan serve -
Model file ada
rice_leaf_disease_model.kerasor.h5- Di folder
rice leaf diseases dataset/
-
Network connectivity
- Pastikan device/emulator bisa akses server
- Test dengan curl atau Postman
🎨 Customization Examples
Ubah Warna Tema
// Di dashboard_klasifikasi.dart
backgroundColor: const Color(0xFF0F703A), // Hijau
// Di result_screen.dart
backgroundColor: const Color(0xFF0F703A), // Hijau
Ubah Loading Text
// Di dashboard_klasifikasi.dart
// Di _handleClassification() method
setState(() {
_isLoading = true;
_errorMessage = null;
});
Tambah Loading Animation
// Import di top
import 'package:flutter_spinkit/flutter_spinkit.dart';
// Ganti CircularProgressIndicator dengan:
SpinKitRing(color: Colors.white)
🔍 Testing Tips
Test 1: Check API Connection
# Di command line
curl -X GET http://127.0.0.1:8000/api/classification/test
# Should return: {"success": true, "message": "..."}
Test 2: Manual Classification
curl -F "image=@path/to/image.jpg" \
http://127.0.0.1:8000/api/classification/classify
Test 3: In App
- Buka Flutter app
- Pilih gambar daun padi
- Tap "Klasifikasi Sekarang"
- Tunggu hasil (1-2 detik)

🆘 Troubleshooting
| Error | Solusi |
|---|---|
| "Network error" | Update URL di classification_service.dart |
| "Request timeout" | Pastikan semua 3 servers berjalan |
| "Model not loaded" | Cek Python API server - lihat console output |
| Image can't be picked | Grant camera/storage permissions |
| Screen blank | Pastikan ResultScreen menerima parameter yang benar |
