Improve AppendIndicator and ScrollDataView onAppend #8

Closed Aoi-hosizora closed 3 years ago

Aoi-hosizora commented 3 years ago

Need to add a threshold for AppendIndicator to check if it needs to append when the list is short.

And fix the scroll invoked when the onAppend invoked but it has been scrolled up.

Update: return false for NotificationListener.

Fix for 1:

void _onPointerMove(PointerMoveEvent e) {
  if (e.down && _pointerDownPosition != null) {
    bool short = _extent == 0;
    if (short && _pointerDownPosition - (e.position?.dy ?? 0) > _kPointerMovingThreshold) {
      _show(); // 2
    }
  }
}

Fix for 2: (only for PaginationListView, wait for v1.2)

widget.data.addAll(list);
if (notShortAndBottom) {
  widget.controller?.scrollDown(); // <<<
}
