- ✅ **Teacher Materials Upload Page** - Nova tela dedicada para professores enviarem materiais para a IA
  - Ficheiro: `lib/features/materials/presentation/pages/teacher_materials_page.dart`
  - **FASE 1**: Criar tela com AppBar "Materiais da Turma" e design consistente
  - **FASE 2**: Ligar card "Upload Conteúdo" do dashboard a esta tela via `Navigator.push`
  - **FASE 3**: Listar materiais do Firestore com `StreamBuilder` filtrado por `teacherId`
    - Campos: `teacherId`, `fileName`, `fileUrl`, `type`, `createdAt`
    - Ordenação: `createdAt` descendente
    - Cards com ícone do tipo (PDF vermelho, Imagem azul) e data formatada
  - **FASE 4**: FloatingActionButton com bottom sheet para adicionar ficheiros

    - Snackbars de feedback (sucesso verde, erro vermelho)
    - Loading indicator no FAB durante upload
  - **Dependências adicionadas**: `file_selector: ^1.0.3` ao pubspec.yaml
  - A lista atualiza automaticamente via StreamBuilder após upload

- ✅ **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**

  - 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
