pages property

int get pages

The total number of pages.

Setting this clamps value to pages - 1 if it would otherwise be out of range.

Contract:

• Throws AssertionError if pages <= 0.

Implementation

int get pages => _pages;

set pages (int pages)

Implementation

set pages(int pages) {
  assert(0 < pages, 'pages ($pages) should be > 0');
  if (_pages == pages) {
    return;
  }

  _pages = pages;
  if (pages <= super.value) {
    // This already notifies listeners, so we don't need to call notifyListeners again.
    super.value = pages - 1;
  } else {
    notifyListeners();
  }
}
