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).
Problem
- Genz Updates could still return 403/Cloudflare in extension requests even when the same site worked in WebView.
- The extension HTTP path primarily used cached cookies from settings instead of reliably using the current WebView cookie jar.
- Cloudflare challenge detection was too narrow (mostly English markers) and could misclassify localized challenge pages as resolved.
Solution
- Prefer live WebView cookies for outgoing extension HTTP requests, with settings cookies as fallback.
- Sync cookie + user-agent from embedded WebView on onLoadStop in addition to history updates.
- Expand challenge detection with additional multilingual and platform markers.
Implementation Details
- Updated `MCookieManager.interceptRequest` to read cookies from `CookieManager.getCookies()` and use them as the request `Cookie` header when available.
- Added `_syncCookieAndUaFromWebView()` in `MangaWebView` and invoked it from both `onLoadStop` and `onUpdateVisitedHistory` to persist fresh clearance cookies immediately.
- Introduced a centralized `_cloudflareChallengePattern` in `m_client.dart` and reused it in `_containsCloudflareChallengeHtml` and `_isCloudflareChallengePage` for consistent challenge detection.

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.
- Introduce _addLog() helper to manage log insertion
- Enforce a maximum log history of 200 entries to prevent unbounded memory growth
- Replace direct _logsNotifier.value.add(event) with safe, immutable-style list update
- Improve log handling consistency and avoid mutating notifier state in place
- new file item_type_filters.dart for the hiddenItemTypes function.
- reduces code duplication in statistics_screen, categories_screen and base_library_tab_screen
The "Show extensions" Button was not working properly when categories were hidden.
An Exception would throw:
```
_AssertionError ('package:flutter/src/material/tab_controller.dart': Failed assertion: line 202 pos 12: 'value >= 0 && (value < length || length == 0)': is not true.)
```
And jump to the end of the tab list regardless of where you clicked the button.
- Extract localizedItemType() from `base_library_tab_screen.dart`
- Add localizedSources() and localizedExtensions() for browse_screen.dart
- Reduce if-statements in statistics_screen.dart
- Reduce if-statements in categories_screen.dart
- Reduce if-statements in browse_screen.dart
- Change _tabList String-list to be a list of ItemType
- Change its name to _visibleTabTypes
- Use that list in getCurrentItemType(), instead of creating a new list
