HomePage class

The main home page of the CulicidaeLab application.

This stateful widget represents the primary interface that users see when opening the app. It provides a tabbed interface with five main sections:

  • Home: Welcome screen with feature overview and navigation
  • Classification: Camera-based mosquito identification using AI
  • Gallery: Mosquito species information and visual gallery
  • Diseases: Disease information related to mosquitoes
  • Map: Interactive mosquito activity map (WebView)

Architecture & State Management

The widget manages navigation state using IndexedStack for efficient memory usage and state preservation across tabs. It integrates with:

Key Features

  • Bottom Navigation: Five-tab navigation with custom icons
  • Language Selection: Multi-language support (EN, ES, RU) via app bar menu
  • Model Preloading: Automatic PyTorch Lite model initialization on startup
  • Responsive Design: Gradient background and adaptive layouts
  • State Preservation: Maintains state across tab switches using IndexedStack
  • Error Handling: Graceful model loading failure handling

├── Home Tab (Welcome screen with feature cards)
├── Classification Tab (ClassificationScreen)
├── Gallery Tab (MosquitoGalleryScreen)
├── Diseases Tab (DiseaseInfoScreen)
└── Map Tab (WebViewScreen)

Performance Considerations

  • Uses IndexedStack to maintain widget state across navigation
  • Preloads ML model asynchronously to avoid blocking UI
  • Implements proper lifecycle management for model loading
  • Optimizes memory usage by lazy-loading tab content

Localization Support

The screen supports multiple languages through:

  • Dynamic language switching via app bar menu
  • Localized navigation labels and content
  • Proper text direction and formatting support
  • Persistent language preference storage
