Replace per-widget Isar StreamBuilder usage with a single shared
library index managed in MangaHomeScreen.
- Subscribe once to manga updates and build a name -> Manga map
- Pass libraryManga down to card widgets instead of querying per item
- Remove StreamBuilder logic from MangaImageCardWidget and list tile
- Use library data for cover, tracker image, and favorite state
- Add favorite overlay indicator based on libraryManga
- Clean up redundant filtering and improve performance
This reduces rebuild overhead and avoids multiple database listeners
per list/grid item.
`addListener` is called inside the `data:` callback of `build()`.
Every single time the widget rebuilds, which happens on scroll, on tab switch,
on any `setState`, it adds *another* listener to `_scrollController`,
stacking up indefinitely. With 100 items and active scrolling,
you can easily accumulate hundreds of listeners,
each one firing `setState` + `_loadMore()` on every scroll-to-bottom.
Fix: Move the listener setup to `initState()` and remove it in `dispose()`
MangasListState previously stored selected manga IDs as List<int>.
Every visible library card called .contains() on that list once per
rebuild to determine its highlight state, making each check O(n) in
the number of selected items. The provider's own update/selectAll/
selectSome methods also used .contains() and .remove() on a List.
Change the state type to Set<int> throughout, making all membership
checks O(1). Updated all consumers: library_gridview_widget,
library_listview_widget, library_app_bar, library_dialogs, and
MangasSetIsReadState.
call `_processCropBorders()` once, from _initCurrentIndex and after new pages arrive.
Also make _processCropBorders idempotent by the existing _cropBorderCheckList guard
fix for the "jump back" bug that occurred when scrolling up in vertical continuous and webtoon reader modes.
- `ChapterPreloadManager` was maintaining its own `_currentIndex`.
- When prepending previous chapter pages, the index was being incremented
twice (once in the manager + once in `_handlePrevChapterPrepended`).
- This caused `itemScrollController.jumpTo()` to overshoot, resulting in
a visible jump forward (perceived as "jump back" while trying to scroll up).
- Removed all index management (`_currentIndex`, getter, setter, startIndex)
from `ChapterPreloadManager` and `ReaderMemoryManagement`.
- `ChapterPreloadManager` is now a pure data container (only manages `_pages`).
- `_handlePrevChapterPrepended` now captures the **current visible top index**
*before* prepending and adjusts the scroll position only once.
- `_readProgressListener` is now the single source of truth for `_currentIndex`.
- Removed stale `initialScrollIndex` logic from preload initialization.
Introduce a unique `ValueKey` for each page (chapter ID + page index) and wrap items in `KeyedSubtree`. This ensures Flutter can correctly preserve widget identity when the preload manager inserts or prepends pages.
Previously, every `setState` triggered by page preloading caused the entire list to rebuild, leading to visible lag. With stable keys, only newly added pages rebuild while existing ones retain their state.
This significantly reduces jank, improves scroll smoothness, and makes chapter transitions nearly seamless.
`ChapterPreloadManager.preloadPrevChapter` does `_currentIndex += prependCount` (internal manager index).
Then `_handlePrevChapterPrepended` in `reader_view.dart` does the exact same thing again to the UI’s `_currentIndex` before calling `jumpTo`.
The UI state already handles the adjustment + `jumpTo` correctly.
The manager’s internal `_currentIndex` is not needed for continuous mode (the `ItemPositionsListener` overrides it anyway).
- prevent stale settings overwrites by reloading settings inside Isar write txn before updating chapterPageUrlsList
- guard getPageLength() against missing chapter entries and empty urls to avoid No element crashes
- simplify read-threshold calculation in setPageIndex() via totalPages/pagesRemaining for continuous and paged modes
- map visible continuous double-page indices to actual page indices in _readProgressListener before persisting progress
- snapshot item positions and clamp indices during fast scrolling to avoid volatile first/last access races
- Added new localization strings for total, mean per title, completion rate, watching time, reading time, average chapters per title, read percentage, and entries in multiple languages.
- Enhanced the History model to include readingTimeSeconds.
- Updated AnimeStreamController and ReaderController to track reading time and save it to history.
- Implemented reading time tracking in Anime and Novel reader views.
- Introduced statistics calculations for total reading time across histories.

- Introduced CalendarDay widget to display individual days with event indicators.
- Created CalendarHeader widget for navigating between months.
- Developed CalendarIndicator for visualizing events on specific days.
- Implemented UpcomingCalendar to manage the calendar view and event loading.
- Added UpcomingItem widget for displaying individual upcoming manga with cover images.
- Introduced FetchInterval utility to calculate fetch intervals based on chapter upload dates.
- Refactored updateMangaDetail to utilize FetchInterval for smart update days.

- to prevent old entries (before sourceId was introduced) from accidentally using conflicting sources with the same name even if they are not installed
This commit improves memory management, reduces redundant interpreter
instantiation, and standardizes service usage patterns.
- Add `dispose()` to `ExtensionService` interface and implement it across
Dart, JS, LNReader, and Mihon services.
- Replace repeated interpreter creation in `DartExtensionService` with a
persistent `_interpreter` instance initialized once in the constructor.
- Add disposal logic for JS DOM selector and Cheerio instances to prevent
memory leaks.
- Introduce `withExtensionService()` helper to ensure services are always
disposed after use.
- Update call sites across the codebase to use `withExtensionService()`
or manual try/finally disposal.
- Improve isolate service message handling by extracting `responsePort`
earlier.
- Ensure safer defaults (e.g., returning empty lists, const lists) when
service calls fail.
