forward method

void forward({
  1. bool align = true,
  2. bool? animate,
})

backward will move the scrollbar with a distance of one item in the bottom direction. If value of align is true, the last visible item will be aligned.

Implementation

void forward({bool align = true, bool? animate}) {
  if (align) {
    final lastIdx = ((offset + inside) / scrollPerItem - 1).floor() + 1;
    if (lastIdx >= itemCount) {
      return;
    }
    scrollToItem(lastIdx, animate: animate);
  } else {
    _scrollToPos(offset + scrollPerItem, animate: animate);
  }
}
