Fix exception when using "Select Widget Mode" of the Flutter Inspector:
```
Exception has occurred.
FlutterError (Tried to modify a provider while the widget tree was building.
If you are encountering this error, chances are you tried to modify a provider
in a widget life-cycle, such as but not limited to:
- build
- initState
- dispose
- didUpdateWidget
- didChangeDependencies
Modifying a provider inside those life-cycles is not allowed, as it could
lead to an inconsistent UI state. For example, two widgets could listen to the
same provider, but incorrectly receive different states.
To fix this problem, you have one of two solutions:
- (preferred) Move the logic for modifying your provider outside of a widget
life-cycle. For example, maybe you could update your provider inside a button's
onPressed instead.
- Delay your modification, such as by encapsulating the modification
in a `Future(() {...})`.
This will perform your update after the widget tree is done building.)

Resolved an issue where items could not be added to the tracker due to the use of an incorrect ID. This caused `parseTrackResponse()` to fail in locating the 'included' key within `jsonResponse`, leading to a null return. As a result, an exception was thrown in `tracker_widget.dart` at line 134 when accessing `widget.trackRes.title!,` triggering a _TypeError (Null check operator used on a null value)_.
- Added VirtualMangaList widget for displaying manga pages in a virtual scrolling list.
- Introduced VirtualPageManager to handle page loading, caching, and memory optimization.
- Created VirtualReaderView to integrate virtual scrolling with PhotoView for enhanced reading experience.
- Implemented page loading states and memory cleanup mechanisms in VirtualPageManager.
- Added debug information overlay for monitoring virtual page manager statistics.
- Enhanced user experience with callbacks for chapter transitions and page changes.
- Introduced `TransitionViewPaged` and `TransitionViewVertical` widgets to handle chapter transitions.
- Created `ChapterTransitionPage` widget to display transition information between chapters.
- Updated reader view logic to incorporate transition pages when navigating chapters.
- Enhanced `UChapDataPreload` model to support transition states and next chapter information.
feat(localization): add chapter transition messages in multiple languages
fix(dependencies): update Dart SDK and dependencies
- Updated Dart SDK constraint to ^3.8.0.
- Changed `epubx` dependency to use the latest version from GitHub.
- Move manageExternalStorage inside if (android), as it is Android only.
- Cache permission state, to only check for permission once per app start preventing redundant checks.
- Made `initDB` fully async to enhance efficiency and avoid sync operations
Extract `CustomMaterialPlayOrPauseButton` class from *mobile.dart* and `CustomMaterialDesktopPlayOrPauseButton` class from *desktop.dart* into *play_or_pause_button.dart* to eliminate code duplication and improve maintainability.
Prevent an AssertionError in the Slider widget when the skip duration
button causes the value to exceed the video's maximum duration.
Clamp the Slider's value to the range [0, max]
using `clamp(0.0, maxValue).toDouble()` to ensure it stays within bounds.
Exception example:
```
Exception has occurred.
_AssertionError ('package:flutter/src/material/slider.dart': Failed assertion: line 199 pos 10: 'value >= min && value <= max': Value 1410000.0 is not between minimum 0.0 and maximum 1409533.0)
```
- Resolved the same timestamp conversion issue that affected MyAnimeList.
- Previously, seconds-to-milliseconds conversion and `DateTime.now()` were applied twice — once on `login()` and once in `_getAccessToken()` — resulting in incorrect expiry dates (e.g., year 57349).
- Updated Kitsu’s URL from `.io` to `.app`.
Remove incorrect expiresIn calculation in `OAuth.fromJson`. The `login()`
function of the MyAnimeList class already sets expiresIn as an absolute timestamp in milliseconds.
Multiplying by 1000 and adding the current timestamp in fromJson caused
expiresIn to be inflated, making the expiration check in `_getAccessToken()`
always false, skipping token refresh and returning an invalid token.
Users can now add Mangas/Animes to a **manually** created Mangayomi/local folder.
Feature as described:
```

Chapter 1/
1.jpg
...
Chapter 2.cbz
...
Anime Title/
cover.png (optional)
Episode 1.mp4
Episode 2.mkv
```
The folder (if exist) will be scanned once per app start.
**Supported filetypes:** (taken from lib/modules/library/providers/local_archive.dart, line 98)
```
Videotypes: mp4, mov, avi, flv, wmv, mpeg, mkv
Imagetypes: jpg, jpeg, png, webp
