nextPage method

void nextPage({
  1. required int pageCount,
})

Advances to the next page if not already on the last page.

pageCount is the total number of pages in the document. The call is a no-op when already on the last page or when pageCount ≤ 0. Notifies listeners if the page changed.

Implementation

void nextPage({required int pageCount}) {
  if (pageCount <= 0) return;
  final next = _currentPage + 1;
  if (next >= pageCount) return;
  _currentPage = next;
  notifyListeners();
}
