I struggling to get data form a Firebase collection into a Sliverlist.
Every example I found like this, returns only one Sliverlist, but I've multiple.

The goal I want to achive is a list of Sliverlists, where some have dynamic data en other doesn't

This is the part of my code where its happens:

 return Scaffold(
 body: CustomScrollView(
 slivers: <Widget>[
 SliverAppBar(
 // omitted
 floating: false,
 pinned: true,
 flexibleSpace: FlexibleSpaceBar(
 centerTitle: false,
 collapseMode: CollapseMode.parallax,
 // omitted
 ),
 ),
 ),
 SliverPadding(padding: EdgeInsets.all(10.0)),
 StreamBuilder(
 stream: Firestore.instance.collection("books").snapshots(),
 builder: (BuildContext context, AsyncSnapshot snapshot) 
 return SliverList(
 delegate: SliverChildBuilderDelegate(
 (BuildContext context, int index) 
 DocumentSnapshot ds = snapshot.data.documents[index];
 return Row(
 textDirection: TextDirection.ltr,
 children: <Widget>[
 Expanded(child: Text(ds["title"])),
 Expanded(child: Text(ds["author"])),
 ],
 );
 ,
 childCount: snapshot.data.documents.length,
 ),
 );
 ,
 ),
 SliverPadding(padding: EdgeInsets.all(10.0)),
 SliverList(
 delegate: SliverChildListDelegate(
 [
 StaticWidget(),
 StaticWidget(),
 ],
 ),
 ),
 SliverPadding(padding: EdgeInsets.all(25.0)),
 ],
 ),
 // omitted

I getting the following error:

Any help would be very welcome!
