How the Solution Works

1. Home Screen:

   • Acts as the main hub, providing navigation options to the other two screens.

2. Generate Dogs Screen:

   • The "Generate!" button triggers an API request to fetch a random dog image.
   • The fetched image is displayed and added to the LRU cache.
   • The cache is implemented with a size limit of 20 images, ensuring memory efficiency.
   • Data is persisted using RoomDB to retain images across app sessions.

3. Recently Generated Dogs Screen:

   • Displays all cached images in a scrollable gallery.
   • The "Clear Dogs" button clears the RoomDB cache and the gallery.
