I'm currently using SliverStaggeredGrid to build my appication but since it has been removed I am unable to use it not can find any other code that has replaced it. I tried using a lower version but since flutter creates certain dependencies, I was unable to use the lower version. How do I get about this:
This is the code for the SliverStaggeredGrid:
: SliverStaggeredGrid.countBuilder(
staggeredTileBuilder: (c) => const StaggeredTile.count(1, 1.5),
crossAxisCount: 2,
mainAxisSpacing: 1,
crossAxisSpacing: 0,
itemBuilder: (context, index) {
Items model = Items.fromJson(
snapshot.data!.docs[index].data()!
as Map<String, dynamic>);
return Padding(
padding: const EdgeInsets.all(8.0),
child: ItemsDesign(
model: model,
context: context,
),
);
},
itemCount: snapshot.data!.docs.length,
);
EDIT:
Dependencies version:

This probably isn't an answer you want to hear, but you probably can't use SliverStaggeredGrid as-is any more.
You might have to switch to newer code from a plugin, for example flutter_staggered_grid_view or masonry_grid. I believe SliverQuiltedGridDeletate in the flutter_staggered_grid_view package probably does what you need.
An alternative could be to copy the source code for SliverStaggeredGrid directly into your project or fork the plugin (assuming it's coming from a plugin) and update only what you need - as long as you can update it for the most recent flutter version it should work, but there's probably a good reason for it being deprecated so I wouldn't recommend it.
