Semi-transparent container (colorScheme.surface.withOpacity(0.8)) - Rounded corners (12px) - Subtle shadow (colorScheme.shadow.withOpacity(0.1), blurRadius: 8) - Positioned below notification bar to avoid overlap - ✅ **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 - Opções: PDF (file_selector), Imagem da Galeria (image_picker), Foto da Câmara (image_picker) - **FASE 5**: Upload para Firebase - Firebase Storage: `materials/{teacherId}/{timestamp}_{filename}` - Firestore document na coleção `materials` - 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** - "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) - ✅ Fixed login page animations - ✅ Added dynamic background effects - ✅ Updated language policy - ✅ Improved text visibility - ✅ Created progress documentation ### **Last Week:** - ✅ Implemented role selection page - ✅ Added Portuguese localization - ✅ Fixed navigation flow - ✅ Improved splash screen - ✅ Setup internationalization --- ## 🎯 NEXT PRIORITIES ### **Immediate (This Week):** 1. **Update signup page** with Portuguese and improved design 2. **Implement Firebase authentication** for real login 3. **Add role-based routing** after login 4. ~~**Create basic dashboard** placeholder~~ ✅ **Student & Teacher dashboards implemented** ### **Short Term (Next 2 Weeks):** 1. **Complete authentication system** 2. **Build student dashboard** 3. **Implement basic quiz system** 4. **Add analytics tracking** ### **Medium Term (Next Month):** 1. **Integrate AI tutor** 2. **Build teacher dashboard** 3. **Implement RAG engine** 4. **Add comprehensive testing** --- ## 📱 DEVICE COMPATIBILITY ### **Tested Devices:** - ✅ **Samsung S928B (Android 16)** - Primary testing device - ⏳ **iOS Devices** - Pending testing - ⏳ **Other Android** - Pending testing ### **Performance:** - **Startup Time:** ~3 seconds - **Navigation Speed:** Fast - **Animation Performance:** Smooth (60fps) - **Memory Usage:** ~150MB --- ## 🎉 ACHIEVEMENTS ### **Milestones Reached:** - ✅ **Project Kickoff** - Complete - ✅ **UI/UX Foundation** - Complete - ✅ **Internationalization** - Complete - ✅ **Device Deployment** - Complete - ✅ **User Testing Ready** - Complete ### **Technical Achievements:** - ✅ Successfully deployed to Samsung device - ✅ Implemented complex animations - ✅ Created scalable architecture - ✅ Established development workflow - ✅ Set up quality standards --- ## 📞 TEAM STATUS ### **Current Team:** - **Developer:** Active - **Testing:** In Progress - **Documentation:** Up to Date - **Quality Assurance:** Active --- **📊 Last Updated: 2026-05-23 17:11** **🔄 Auto-Update: Enabled** **📈 Progress Tracking: Real-time** --- *This document is automatically updated as development progresses.
