Performance is significantly slower than listview

[NewITCorp]

Hi, thanks for a nice library.
it is really easy to use and makes my code very clean and short.
however I find it quite laggy during acroll for both side for records around 1000 and columns around 20, this symptom does not exist in listview.
Any suggestion please?

Hi @NewITCorp
Sorry for the super late reply. The reason that's the case is because I'm not recycling elements that are passed to the bidirectional scroll. I recommend trying out Slivers and see how well it performs :)

Is it possible to have recycling slivers and bidirectional scrolling?

Hey sascha3212 and NewITCorp! This might be a super late update but finally got around to finishing adding slivers :)

@toufikzitouni Do you have an example with slivers? I am trying to add a SliverGrid as the child and am receiving an error "A RenderSliverFillRemainingWithScrollable expected a child of type RenderBox but received a child of
type RenderSliverGrid"

Here is my code:

BidirectionalScrollViewPlugin(
                            childHeight: height.toDouble(),
                              childWidth: width.toDouble(),
                            child: SliverGrid(
                              gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
                                  crossAxisCount: garden.columns),
                              delegate: SliverChildBuilderDelegate(
                                (context, index) {
                                  return cells[index];
                                },
                                childCount: cells.length,
                              ),
                            ),
                          );

Note: cells[index] could just be a container or text.
