There is a extension in chapters_model.dart lets move the next/previous lookups in there and only pass the required paramaters to fetch previous/next chapters.

That way we can re-use it when needed.

Chapter? prev;
final earlier = chapters.where((c) => c.startPosition < position - threshold).toList();
if (earlier.isNotEmpty) prev = earlier.last;
final target = prev ?? chapters.first;
ref.read(videoPlayerProvider).seek(target.startPosition);
resetTimer();
}

void _nextChapter(WidgetRef ref) {
final chapters = ref.read(playBackModel.select((value) => value?.chapters)) ?? [];
if (chapters.isEmpty) return;
final position = ref.read(mediaPlaybackProvider).position;
Chapter? next;
for (final c in chapters) {
if (c.startPosition > position) {
next = c;
break;
}
}
if (next != null) {
ref.read(videoPlayerProvider).seek(next.startPosition);
} else {
// fallback: load next video
final nextVideo = ref.read(playBackModel.select((value) => value?.nextVideo));
if (nextVideo != null) ref.read(playbackModelHelper).loadNewVideo(nextVideo);
}

I'm not sure about loading the next video. Would it not be better to disable the next chapter button if there is no next chapter?
