Flutter ios doesn’t scroll correctly to the top

I’ve some scrolls in my app and so they work completely within the android however within the ios they do not work correctly when they’re scrolled to the top.

it needs to be like this:

display code:
the 85 backside padding is for backside navigation.

ListView.separated(
                        padding: EdgeInsets.solely(
                            backside: constraints.maxHeight > (dimension.peak - 70)
                                ? 85
                                : 0),
                        itemBuilder: (context, index) {
                          ListModel listing = bookProvider.lists[index];
                          return HorizontalList(
                            listing: listing,
                            itemOnTap: (index) => Navigator.push(
                                context,
                                MaterialPageRoute(
                                  builder: (context) => BookDetailsScreen(
                                      ebook: listing.books[index]),
                                )),
                          );
