Option 1: State Management with Provider - Favorites Management App Create a new Flutter project. Add the Provider package: Add provider: ^6.0.5 to your pubspec.yaml file and run flutter pub get. Create a Favorites model: In the lib directory, create a new file called favorites.dart. Define a Favorites class that extends ChangeNotifier: A List named items to store favorite items. Methods like addItem(String item) and removeItem(String item) to manage favorites. Use notifyListeners() after modifying the list to update the UI. Create a Product List UI: In main.dart, wrap MaterialApp with ChangeNotifierProvider to provide the Favorites class to the widget tree. Use a Scaffold with an AppBar titled "Product List". Use ListView.builder inside the body of Scaffold to display a list of product items. For each item: Use a Card widget with Text to display product details. Add an IconButton to add the product to favorites. Favorites Screen: Add a FloatingActionButton in the product list screen that navigates to the favorites screen. Create a new screen to display favorite items using ListView.builder. Wrap ListView.builder with a Consumer widget to update the list automatically when an item is added or removed. Make It Interactive: Allow users to remove items from favorites by adding an IconButton with a delete icon. Test Your App: Verify that users can add items to the favorites list and view or manage them on the favorites screen.
