Summary of Changes

Hello @cka-dev, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on modernizing the Cahier application by updating its core dependencies, significantly enhancing the user interface and experience, and refining the underlying data management. The changes introduce adaptive layouts for better multi-device support, streamline note editing and drawing functionalities, and improve the robustness of data persistence with new database migrations. The overall goal is to create a more responsive, maintainable, and user-friendly application.

Highlights

  • Dependency Updates: Numerous dependencies including Android Gradle Plugin, Kotlin, Compose BOM, Hilt, Room, and Lifecycle libraries have been updated to their latest versions, ensuring the project uses modern and stable components.
  • Adaptive UI and UX Enhancements: The application now leverages Material 3's ListDetailPaneScaffold for improved adaptive layouts across various screen sizes. UI components for both text and drawing canvases have been refactored into smaller, more manageable composables, enhancing maintainability and user experience. New icons and tooltips have been introduced for better visual feedback.
  • Data Model and Persistence Improvements: The Note data model has been extended to include a clientBrushFamilyId for persisting selected drawing brushes. Database version has been incremented from 5 to 8, with a new migration (MIGRATION_7_8) implemented to handle changes in NoteType enum values (from uppercase to PascalCase). The StrokeEntity file has been removed, indicating a streamlined approach to stroke storage.
  • ViewModel Refinements: ViewModel logic has been updated to align with UI changes, including handling of new brush family IDs, improved image processing for drag-and-drop, and a new event channel for opening notes in new windows. Lifecycle-aware state collection (collectAsStateWithLifecycle()) is now widely adopted.
  • Modularization of Drawing Toolbox: The drawing canvas toolbox has been modularized into dedicated composables (DrawingToolbox, HorizontalToolbox, VerticalToolbox), allowing for responsive layout adjustments based on screen orientation or window size.

Code Review

This pull request introduces significant improvements across the application, focusing on UX enhancements, code refactoring, and addressing feedback from a Modern Android Development (MAD) review. Key changes include adopting collectAsStateWithLifecycle, enabling edge-to-edge display, refactoring large composables into smaller, more manageable ones, and improving adaptive layouts for different screen sizes. The data layer has also been updated with a database migration to preserve user data and support for custom brushes. Overall, this is a high-quality update that modernizes the codebase and enhances the user experience. I've included a few suggestions for further refinement.
