DiseaseInfoScreen class
Searchable gallery screen for browsing mosquito-borne diseases.
This screen provides an interactive interface for exploring disease information:
- Search Functionality: Real-time search with query filtering
- Disease Cards: Visual cards showing disease images, names, and descriptions
- Vector Information: Display of mosquito species that transmit each disease
- Prevalence Data: Geographic distribution information
- Error Handling: Proper loading states and error recovery
- Empty States: Helpful messaging when no results are found
The screen uses the Provider pattern with DiseaseInfoViewModel for state management. It loads disease data on initialization and provides search functionality that filters results based on user input.
Key Features:
- Real-time search with debounced filtering
- Visual disease cards with images and key information
- Loading states and error handling
- Empty state messaging for better UX
- Navigation to detailed disease screens
