by extracting the helper methods `_seekTo()` and `_seekBy()`.
This also fixes a potential bug, where in line 1634 it was calculated
`skipDuration - _currentPosition.value.inSeconds` instead of the other way around.
That doesn't make sense. If currentPosition = 120 and skipDuration = 10, this becomes:
`_tempPosition = Duration(seconds: 10 - 120)`; so `= Duration(seconds: -110)`
A negative duration makes no sense as a UI indicator of a seek target.
By extracting:
```
SystemChrome.setEnabledSystemUIMode(
SystemUiMode.manual,
overlays: SystemUiOverlay.values,
);
```
to a file `system_ui.dart` and calling the method `restoreSystemUI()`
Changes:
- Add season-keyword regex (staffel, season, saison, temporada) and
episode-keyword regex (folge, episode, ep.) to reliably extract
the correct number regardless of name format
- parseChapterNumber() now encodes season context into the sort key
(season * 100000 + episode) so multi-season anime sort correctly
across seasons without mixing episode numbers
- Add parseEpisodeNumber() which strips season context and returns
only the episode number within a season; use this for tracker
updates (MAL/AniList/Kitsu) and AniSkip lookups, where the tracker
entry is already season-specific
- Switch updateTrackChapterRead and getAniSkipResults to
parseEpisodeNumber to fix incorrect episode reporting for
multi-season anime
- Compile all RegExp objects as static finals instead of per-call
instantiation
- Refactor duplicated parse logic into a single private _parse()
method with an applySeason flag
- remove the reverse parameter because false is already the model default, so passing it is redundant.
- flip the reverse bool, to keep the chapter sorting of already added manga the same.
Otherwise the user would have to change the sorting orientation for the chapters in the library.
- Add ChapterRecognition for numeric chapter parsing
- Replace old comparators with chapter‑number–aware sorting
- Unify sort modes and simplify list handling
- Rewrite updateMangaDetail with URL‑based dedupe
- Preserve read state across scanlators
- Update existing chapters instead of recreating
- Only create Update entries for new unread chapters
- Recompute smartUpdateDays using combined chapter list
- Remove outdated reversed/index‑based logic
`chapters.length - chapters.reversed.toList().indexOf(chapters.reversed.toList()[finalIndex]) - 1;`
is just the same as
`chapters.length - 1 - finalIndex`
but it creates two lists, which is wasteful.
- Replace synchronous Isar writes with async transactions in `AboutScreen`
- Make `AppLogger.init()` and `dispose()` fully async and guarded with `_busy`
- Remove `StreamController` queue and write directly to the IOSink
- Prevent double‑initialization and race conditions using `_initialized` + `_busy`
- Update log toggle handler to await logger init/dispose for consistency
Fix following Exception when disabling and re-enabling logger:
```
Exception has occurred.
StateError (Bad state: Stream has already been listened to.)
```
The horizontal layout (_buildHorizontalLayout) used FittedBox as a
shared scaffold for both vertical and horizontal reading modes.
FittedBox passes unbounded width constraints to its child, which caused
RenderFlex to throw "children have non-zero flex but incoming width
constraints are unbounded" when Row + Expanded children were used.
This cascaded into a chain of "RenderBox was not laid out" assertions
all the way up through IntrinsicHeight, ConstrainedBox, FittedBox,
LayoutBuilder, and into the ScrollablePositionedList in
image_view_webtoon.dart.
Fix: split the two layout paths before they reach a scaffold widget.
The vertical path keeps FittedBox (safe, maxWidth is capped at 480px).
The horizontal path uses SizedBox(width: MediaQuery screenWidth) so
Row/Expanded always receive a finite width constraint.
Replace per-card Isar tracking streams with a single subscription in
TrackerSectionScreen.
- Build a mediaId -> Track index at the screen level
- Pass resolved Track? into TrackerLibraryImageCard
- Convert TrackerLibraryImageCard to a plain StatelessWidget
- Remove StreamBuilder, ConsumerStatefulWidget, and keep-alive boilerplate
- Keep the same UI while reducing widget-level DB work
This follows the same parent-index pattern used elsewhere and makes
the tracker library view lighter and easier to maintain.
Remove synchronous Isar queries from each library grid item when
downloadedChapter is enabled.
- Replace per-card download queries with downloadedChapterIdsProvider
- Compute downloadCount via in-memory lookup instead of DB calls
- Eliminate repeated sync queries on rebuilds and tab switches
- Minor cleanup of unread chapter filter
This avoids dozens of synchronous queries per frame and significantly
improves grid performance and responsiveness.
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()`
Each UChapDataPreload holds a GetChapterPagesModel that itself holds all pageUrls, archiveImages, etc. For a 50-page chapter this creates 50 model objects each referencing all 50 URLs.
Fix an Exception:
```
════════ Exception caught by rendering library ═════════════════════════════════
A RenderFlex overflowed by 274 pixels on the bottom.
The relevant error-causing widget was:
Column Column:file:///lib/modules/manga/reader/widgets/chapter_transition_page.dart:28:18
════════════════════════════════════════════════════════════════════════════════
```
Improved: The UI adapts to the reading mode now
