✅ Color-coded badges untuk setiap kelompok kelas

🚀 Quick Start Guide

Step 1: Verify Backend

# Navigate to Laravel project
cd c:\xampp\htdocs\TugasAkhir\sim-pkpps

# Check for syntax errors
php artisan route:list | grep api

# Test login endpoint (replace S001 & password)
curl -X POST http://localhost:8000/api/login \
  -H "Content-Type: application/json" \
  -d '{"id_santri": "S001", "password": "password123"}'

Expected: Response includes kelas (string) and kelas_list (array)

Step 2: Test Flutter App

# Navigate to Flutter project
cd c:\xampp\htdocs\TugasAkhir\sim_mobile

# Clean build
flutter clean
flutter pub get

# Run on device/emulator
flutter run

Test Flow:

Login dengan santri yang punya multiple kelas
Tap tab "Profil"
Expected: Section "Kelas yang Diikuti" muncul
Tap kelompok → ExpansionTile expand
Verify badge "⭐ Utama" di primary kelas

Step 3: Create Test Data (Manual)

-- Connect to your MySQL database
USE sim_pkpps;

-- Insert sample kelas for testing
-- Replace S001 with your test santri ID

-- Kelas 1: PB Putra A (not primary)
INSERT INTO santri_kelas (id_santri, id_kelas, tahun_ajaran, is_primary) 
VALUES ('S001', 1, '2025/2026', 0);

-- Kelas 2: Lambatan B (PRIMARY)
INSERT INTO santri_kelas (id_santri, id_kelas, tahun_ajaran, is_primary) 
VALUES ('S001', 5, '2025/2026', 1);

-- Kelas 3: Cepatan A (not primary)
INSERT INTO santri_kelas (id_santri, id_kelas, tahun_ajaran, is_primary) 
VALUES ('S001', 8, '2025/2026', 0);

-- Kelas 4: Hadist Pemula (not primary)
INSERT INTO santri_kelas (id_santri, id_kelas, tahun_ajaran, is_primary) 
VALUES ('S001', 15, '2025/2026', 0);

-- Verify
SELECT * FROM santri_kelas WHERE id_santri = 'S001';

✅ Testing Checklist (Quick)

Backend

Login returns kelas_list array
Primary kelas has is_primary: true
Field kelas masih ada (backward compat)
Query count < 5 (no N+1)
Response time < 500ms

Frontend

Section "Kelas yang Diikuti" muncul
Primary kelas badge di header
ExpansionTile bisa expand/collapse
Badge "⭐ Utama" di primary kelas
Color coding benar per kelompok
Pull-to-refresh works
Empty state handled (santri tanpa kelas)
Responsive (320px - 800px)

Integration

Admin add kelas → Mobile refresh → Kelas baru muncul
Admin change primary → Mobile refresh → Primary berubah
Old app + New backend → No crash
New app + Old backend → Fallback to single kelas

📋 Full Testing Checklist: See TESTING_CHECKLIST_MULTIPLE_KELAS.md (26 detailed tests)

🐛 Troubleshooting

Problem: kelas_list always empty

Solution:

Check santri_kelas table has data
Run: SELECT * FROM santri_kelas WHERE id_santri = 'YOUR_SANTRI_ID';
If empty, insert sample data (see Step 3 above)

Problem: Primary badge not showing in Flutter

Solution:

Check is_primary column in database
Ensure at least 1 record has is_primary = 1
Pull-to-refresh in app

Problem: ExpansionTile not expanding

Solution:

Check Flutter console for errors
Ensure kelas_list is properly parsed as List
Debug: print(_santriData?['kelas_list']);

Problem: API returns 500 error

Solution:

Check Laravel log: storage/logs/laravel.log
Verify database relationships (kelompok, kelas, santri_kelas)
Test query manually in MySQL
