# PERBAIKAN MOBILE LOGIN & REGISTER - SUMMARY LENGKAP
|
|
|
|
## 🎯 MASALAH YANG DIPERBAIKI
|
|
|
|
Saya sudah **mengidentifikasi dan memperbaiki error** di menu login dan register mobile Anda:
|
|
|
|
### Error yang Diperbaiki:
|
|
1. ❌ Missing null safety checks → ✅ Added proper null checks
|
|
2. ❌ Generic error messages → ✅ Specific, helpful error messages
|
|
3. ❌ No timeout handling → ✅ 30-second timeout added
|
|
4. ❌ Missing error border styling → ✅ focusedErrorBorder added
|
|
5. ❌ No network error handling → ✅ SocketException & TimeoutException handled
|
|
6. ❌ Inconsistent validation → ✅ Standardized across both screens
|
|

|
## 🚀 LANGKAH TESTING
|
|
|
|
### 1. Update Project
|
|
```bash
|
|
cd c:\laragon\www\TA\spk_mobile
|
|
flutter pub get
|
|
flutter clean
|
|
```
|
|
|
|
### 2. Jalankan Backend (Terminal Baru)
|
|
```bash
|
|
cd c:\laragon\www\TA\spk_kontrakan
|
|
php artisan serve
|
|
# Tunggu sampai: "Server listening on: ..."
|
|
```
|
|
|
|
### 3. Verify IP Address
|
|
File: `spk_mobile/lib/config/app_config.dart`
|
|
- Line 13: `static const String _defaultServer = 'http://10.21.24.99:41197';`
|
|
- Sesuaikan dengan IP backend server Anda
|
|
|
|
### 4. Run Mobile App
|
|
```bash
|
|
flutter run
|
|
|
|
# Terminal baru untuk debug logs:
|
|
flutter logs
|
|
```
|
|
|
|
### 5. Test Cases
|
|
- ✅ Login dengan credential benar
|
|
- ✅ Login dengan credential salah (verify error message)
|
|
- ✅ Register akun baru (verify success)
|
|
- ✅ Test tanpa internet (verify "Gagal terhubung" message)
|
|

## 📋 PERUBAHAN DETAIL
|
|
|
|
### login.dart
|
|
**Sebelum:**
|
|
```dart
|
|
if (result['success']) { // ❌ Crash jika null
|
|
```
|
|
|
|
**Sesudah:**
|
|
```dart
|
|
final success = result['success'] ?? false; // ✅ Null-safe
|
|
if (success == true) {
|
|
```
|
|
|
|
### auth_service.dart - Login Method
|
|
**Sebelum:**
|
|
```dart
|
|
Future<Map<String, dynamic>> login({...}) async {
|
|
try {
|
|
final response = await http.post(...);
|
|
final data = jsonDecode(response.body);
|
|
if (response.statusCode == 200 && data['success'] == true) {
|
|
// ...
|
|
} else {
|
|
return {'success': false, 'message': 'Login gagal'}; // ❌ Generic
|
|
}
|
|
} catch (e) {
|
|
return {'success': false, 'message': 'Error: $e'}; // ❌ Tidak helpful
|
|
}
|
|
}
|
|
```
|
|
|
|
**Sesudah:**
|
|
```dart
|
|
Future<Map<String, dynamic>> login({...}) async {
|
|
try {
|
|
final response = await http.post(...)
|
|
.timeout(const Duration(seconds: 30), // ✅ Timeout handling
|
|
onTimeout: () => throw Exception('timeout'),
|
|
);
|
|
// ... better parsing ...
|
|
} on SocketException catch (e) { // ✅ Network error
|
|
return {'success': false, 'message': 'Gagal terhubung ke server'};
|
|
} on TimeoutException catch (e) { // ✅ Timeout error
|
|
return {'success': false, 'message': 'Login timeout'};
|
|
} catch (e) {
|
|
debugPrint('Login exception: $e'); // ✅ Logging
|
|
return {'success': false, 'message': 'Terjadi kesalahan: $e'};
|
|
}
|
|
}
|
|
```
|
|
|

|
|
|
|
## 🔍 DEBUG LOGS
|
|
|
|
Sekarang akan terlihat di `flutter logs`:
|
|
```
|
|
I Login response status: 200
|
|
I Login response body: {"success":true,"data":{"token":"abc123","user":{...}}}
|
|
```
|
|
|
|
Atau jika error:
|
|
```
|
|
I Login response status: 401
|
|
I Login response body: {"success":false,"message":"Invalid credentials"}
|
|
```

## 💡 TIPS DEBUGGING
|
|
|
|
1. **Selalu buka flutter logs:**
|
|
```bash
|
|
flutter logs
|
|
```
|
|
Ini akan show semua debug info dan error details.
|
|
|
|
2. **Test endpoint manually:**
|
|
```bash
|
|
curl http://10.21.24.99:41197/api/login \
|
|
-X POST \
|
|
-H "Content-Type: application/json" \
|
|
-d '{"email":"test@test.com","password":"123456"}'
|
|
```
|
|
|
|
3. **Check backend logs:**
|
|
```
|
|
spk_kontrakan/storage/logs/laravel.log
|
|
```
|
|
|
|
4. **Jika masih error:**
|
|
- Cek Firebase init (OK jika fail, app lanjut)
|
|
- Verify database connection
|
|
- Check API endpoint response format
|
|
- Lihat full error di flutter logs
