LikeSliverBuilder<T extends Object> class

`LikeSliverBuilder<T>`

A dedicated sliver-compatible version of LikeBuilder engineered for rendering network lifecycle states directly inside a CustomScrollView.

Instead of building a single box widget, its builder functions return a list of slivers (List<Widget>).

CustomScrollView Scroll Integration

In traditional Flutter development, placing a standard CircularProgressIndicator or error Container directly into a CustomScrollView's slivers property causes a crash! LikeSliverBuilder prevents this by automatically wrapping default placeholders inside sliver containers (e.g. wrapping standard loaders inside a SliverFillRemaining).

Example Usage:

CustomScrollView(
  slivers: [
    SliverAppBar(title: Text('User Feed')),
    LikeSliverBuilder<List<Post>>(
      observe: () => feedProvider.postsState,
      onLoading: () => [
        SliverToBoxAdapter(child: LinearProgressIndicator()),
      ],
      onSuccess: (posts, isRefreshing, isSWR) {
        return [
          SliverList(
            delegate: SliverChildBuilderDelegate(
              (context, index) => PostCard(posts[index]),
              childCount: posts.length,
            ),
          ),
        ];
      },
    ),
  ],
);
