Created Favorite Page

[VITianLalit]

1. Created Favorite Page:

   • Created favorite.dart file that displays items marked as favorites by the user.

2. Integrating with Explore Page:

   • Modified the explore.dart file to allow users to select and mark items as favorites.
   • Added functionality to update the UI in real-time when items are marked/unmarked as favorites.

3. State Management:

   • Implemented state management using the Provider package to handle the state of favorite items across the application.

4. Local Storage:

   • Used shared_preferences to persist favorite items locally on the user's device. This ensures that favorite items are retained even after the app is closed and reopened.

Files Changed:

• explore.dart
• favorites.dart
• main.dart
• Additional necessary files for Provider setup and shared preferences integration.
