Question: summarize the changes made in this PR and suggest a better title

Answer: This PR introduces several changes to the GroceryList feature in the Kotlin-based application. The primary changes include:

  1. The addition of new repositories: CategoryRepository and IconRepository have been added to the GroceryListScreenViewModel. This allows the ViewModel to fetch categories and icons for groceries.

  2. The introduction of groceryIconsFlow and groceryCategories flows: These flows are used to fetch and handle the state of grocery icons and categories respectively.

  3. The addition of new intents: New intents such as OnCategorySelected, OnCustomCategorySelected, OnIconSelected, OnRemoveGroceryFromList, and OnDeleteProduct have been added to handle user interactions related to category selection, icon selection, grocery removal, and product deletion.

  4. The addition of new functions: Functions like onCategorySelected, onIconSelected, onRemoveGroceryFromList, and onDeleteProduct have been added to handle the new intents.

  5. The update of UI components: The GroceryListScreen and EditGroceryBottomSheetContent components have been updated to accommodate the new features. This includes the addition of category and icon pickers, and delete product confirmation dialog.

  6. The addition of new dialog components: CategoryPickerDialog and IconPickerDialog have been added to allow users to pick a category or an icon for a grocery item.

A more descriptive title for this PR could be: "Enhancement of GroceryList Feature with Category and Icon Selection, and Product Deletion Capabilities".

PR Review

⏱️ Estimated effort to review [1-5] 4, due to the extensive changes across multiple files, including database schema, UI components, and business logic. The PR introduces new features, modifies existing functionalities, and involves UI changes, which require careful review to ensure consistency, performance, and adherence to best practices.
🧪 Relevant tests No
🔍 Possible issues Possible Bug: The `GroceryListViewModel` uses `UUID.randomUUID().toString()` for generating `productId` when adding a custom product. This approach might not guarantee uniqueness across different devices or app installations, potentially leading to conflicts.
Performance Concern: Loading all grocery icons into memory (`groceryIconsFlow`) might lead to increased memory usage, especially if the icons are large or numerous. Consider lazy loading or caching strategies.
🔒 Security concerns No
Code feedback:
relevant fileapp/src/main/java/com/rendox/grocerygenius/screens/grocery_list/GroceryListViewModel.kt
suggestion       Consider implementing a more robust ID generation mechanism that ensures uniqueness across devices and app installations for `productId`. One approach could be combining a device identifier with a timestamp or a sequence number. [important]

suggestion       Implement a caching mechanism for icons to reduce memory usage and improve performance. Icons could be cached in memory with a fixed size LRU cache, or on disk using an appropriate caching library. [important]
relevant lineoverride fun getAllGroceryIcons() = iconDao.getAllGroceryIcons()
relevant fileapp/src/main/java/com/rendox/grocerygenius/ui/components/grocery_list/GroceryGridItem.kt
suggestion       Optimize image loading by checking the size of the `ImageBitmap` and scaling it down if necessary before displaying it in the UI. This can help reduce memory usage for large images. [medium]

suggestion       To improve the maintainability of the `GroceryListViewModel`, consider refactoring large functions and splitting them into smaller, more focused methods. This can make the code easier to understand and test. [medium]

Yep, we'll take care of the performance later. Probably by introducing Coil for loading images from files instead of decoding bitmaps manually.
