Added performance optimizations to all library browser views:
- Added cacheExtent: 500 to all GridView/ListView builders to pre-render
items and reduce stuttering during scrolling
- Wrapped grid items in RepaintBoundary to isolate repaints and improve
performance
- Optimized CachedNetworkImage with:
- fadeInDuration/fadeOutDuration: Duration.zero to remove animation overhead
- memCacheHeight: 300 to limit in-memory cache size
- maxHeightDiskCache: 600 to resize images for better performance
These changes should significantly reduce the stuttering observed when
scrolling the authors grid and filtering books, especially on first load.
Navigation fixes:
- Change goNamed to pushNamed in all library browser pages
- Maintains proper back navigation stack
- Back button now goes step by step instead of to beginning
- Prevents app from closing when navigating back from book detail
Grid layout fixes:
- Book covers are now always square (1.0 aspect ratio)
- Overall card aspect ratio is 0.75 to provide space for text
- Wrap cover in AspectRatio widget instead of using Expanded
- Ensures title and author info always visible below covers
- Fixes issue where book info was missing in series view
- Sort authors by surname (last word in name) instead of first name
- Create FilteredLibraryItemsPage to display books filtered by author/genre/series
- Add navigation from authors/genres/series pages to filtered book lists
- Use AuthorFilter, GenreFilter, and SeriesFilter from shelfsdk
- Add libraryFiltered route with filter parameter support
Users can now:
- Browse authors sorted by surname
- Tap on an author to see all their books
- Tap on a genre to see all books in that genre
- Tap on a series to see all books in that series
This commit implements a comprehensive library browsing feature:
- Add LibraryBrowserProvider with providers for authors, genres, and series data
- Create LibraryAuthorsPage with grid view of authors including images and book counts
- Create LibraryGenresPage with list view of all genres
- Create LibrarySeriesPage with list view of series and book counts
- Update LibraryBrowserPage navigation to route to the new views
- Add routes for /browser/authors, /browser/genres, and /browser/series
- Replace "Not Implemented" toasts with functional navigation
The implementation uses the Audiobookshelf API via shelfsdk to fetch:
- Authors list with metadata (getAuthors)
- Genres from library filter data (getFilterData)
- Series with pagination support (getSeries)
All views follow Material Design 3 patterns and include proper loading/error states.
