## 🔄 RECENT CHANGES
### **Last 24 Hours:**
- ✅ **ETAPA 5: Student Classes List** - Students can now view their enrolled classes on the home page
- New `StudentClassesListWidget` component at `lib/features/dashboard/presentation/widgets/student_classes_list_widget.dart`
- Query: `.collection('enrollments').where('studentId', isEqualTo: currentUser.uid).orderBy('joinedAt', descending: true)`
- For each enrollment document, uses `FutureBuilder` to fetch the corresponding class from `classes` collection
- Layout identical to `TeacherClassesListWidget`:
- Horizontal `ListView.builder` with `scrollDirection: Axis.horizontal`
- 2-row grid layout: Column with cards at index * 2 and index * 2 + 1
- Card size: 200x150 pixels
- Card styling: White background, 16px border radius, subtle shadow
- Card content: Icon (school), class name (bold), class code (grey)
- Title: "As Minhas Turmas" with `textTheme.titleLarge` style
- Loading state: `CircularProgressIndicator` centered in card while loading class data
- Empty state: "Ainda não entraste em nenhuma turma."
- Widget inserted in `StudentDashboardPage` between `QuickAccessWidget` and `ProfileSectionWidget`
- **System is now bidirectional:**
- Professor creates classes → Students can join
- Professor sees list of students in each class (ETAPA 3)
- Students see list of classes they joined (ETAPA 5)
- Both use same visual patterns for consistency
- Testing: After joining a class (ETAPA 4), the class appears immediately in the student's home list
- ✅ **ETAPA 4: Join Class Feature** - Students can now join classes using class codes
- New `JoinClassPage` component at `lib/features/classes/presentation/pages/join_class_page.dart`
- Query: `.collection('classes').where('code', isEqualTo: enteredCode).limit(1)`
- Input: TextField with uppercase formatting, 6 character limit, centered text, letter spacing
- Validation flow:
1. Check if code is empty → show error "Insere o código da turma"
2. Query Firestore for class with matching code
3. If no class found → show error "Código de turma inválido"
4. Check if student already enrolled → show error "Já estás inscrito nesta turma"
5. Create enrollment document in `enrollments` collection
- Enrollment document structure:
```dart
{
'classId': classDoc.id,
'studentId': currentUser.uid,
'studentName': currentUser.displayName ?? email.split('@')[0] ?? 'Aluno',
'joinedAt': FieldValue.serverTimestamp(),
}
```
- Success feedback: Green SnackBar "Entraste na turma com sucesso!" (2 seconds)
- Error feedback: Red SnackBar with specific error message (3 seconds)
- Auto-navigates back to Student Dashboard after successful join
- Loading state: CircularProgressIndicator in button while processing
- Visual design: Teal AppBar (#82C9BD), centered group_add icon, clean white input card
- New "Entrar numa Turma" card added to `QuickAccessWidget` in Student Dashboard
- Card design: Horizontal layout with `Icons.group_add`, white background, rounded corners (16px)
- Testing in Firebase Console:
1. Go to Firestore Database → classes collection
2. Copy the `code` field from any class document
3. In app: Student Dashboard → "Entrar numa Turma"
4. Paste code and tap "Entrar na Turma"
5. Check enrollments collection for new document with correct data
- ✅ **ETAPA 3: Class Students View** - Teachers can now view enrolled students in each class
- New `ClassStudentsPage` component at `lib/features/classes/presentation/pages/class_students_page.dart`
- Query: `.collection('enrollments').where('classId', isEqualTo: classId).orderBy('joinedAt', descending: true)`
- StreamBuilder for real-time updates when students join
- ListTile design with student icon, name, and formatted join date
- Empty state: "Nenhum aluno entrou nesta turma ainda."
- Loading state with `CircularProgressIndicator`
- Error state with error icon and message
- Date formatting using `intl` package (Portuguese format: dd/MM/yyyy)
- Navigation via `GestureDetector` onTap in `TeacherClassesListWidget`
- MaterialPageRoute navigation passing `classId` and `className` as parameters
- AppBar with back button and two-line title (class name + subtitle)
- Consistent visual design: teal colors (#82C9BD), white cards, rounded corners (16px), subtle shadows
- ✅ **ETAPA 2: Classes List Display** - Teachers can now view their created classes
- New `TeacherClassesListWidget` component
- "As Minhas Turmas" section added to Teacher Dashboard
- Real-time Firestore stream with `StreamBuilder`
- Query: `.where('teacherId', isEqualTo: currentUser.uid).orderBy('createdAt', descending: true)`
- **CORREÇÃO**: O erro anterior foi tentar usar `GridView` horizontal para um layout que exige colunas fixas de 2 cards
- **SOLUÇÃO**: Usar `ListView.builder` com `scrollDirection: Axis.horizontal`
- Cada item do ListView é uma `Column` com 2 cards (índice * 2 e índice * 2 + 1)
- Cards mantêm exatamente o mesmo tamanho da lista vertical original
- Layout: Card 1, 3, 5... (top row) | Card 2, 4, 6... (bottom row)
- Scroll horizontal para visualizar todas as turmas
- Padding entre colunas: 12 pixels
- Altura do SizedBox: 280 pixels (suficiente para 2 cards + spacing)
- Empty state: "Ainda não criaste nenhuma turma."
- Loading state with `CircularProgressIndicator`
- Cards styled with white background, rounded corners, and subtle shadow
- ✅ **Fixed Pixel Overflow Issues** - Teacher Dashboard cards
- Replaced fixed `height: 150` with `BoxConstraints(minHeight: 135, maxHeight: 160)`
- Fixed overflow in "Criar Turma" card
- Fixed overflow in "Upload Conteúdo" card
- Cards now adapt better to different screen sizes
- ✅ **Unified Quick Action Cards Text Style**
- "Upload Conteúdo" and "Criar Quiz" cards now have same text alignment as "Criar Turma"
- All cards use `Column` with `crossAxisAlignment: CrossAxisAlignment.start` for text
- Subtitle text now supports 2 lines with `maxLines: 2` and proper line height (1.2)
- Consistent fontSize (16 for title, 12 for subtitle) across all cards
- "Criar Quiz" subtitle updated to "Avaliações interativas" for better description
- ✅ **ETAPA 1: Class Creation Feature** - Teacher can now create classes
- Added "Criar Turma" button in Teacher Dashboard
- Dialog for entering class name
- Auto-generates 6-character random code (A-Z, 0-9)
- Saves to Firestore `classes` collection with name, teacherId, code, createdAt
- Success/error feedback via SnackBar
- ✅ Fixed dashboard overflow issue in QuickAccessWidget
- ✅ Implemented responsive layout with IntrinsicHeight and Flexible
- ✅ Replaced fixed heights with constraints (minHeight: 135, maxHeight: 160)
