SliverListChild Delegate with ListView Causes Bottom Overflow - flutter

Question

I am trying to make a template view page for different text resources. It has a Sliverlist-SliverchildDelegate scrolling effect and inside has a ListView. I have tried wrapping the column with Expanded, Flex, Wrap and SingleScrollView but it either the overflow remains or error becomes incorrect use of parent widget. below is my code:
#override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.blue,
body: SafeArea(
child: CustomScrollView(
slivers: <Widget>[
SliverAppBar(
automaticallyImplyLeading: false,
expandedHeight: 60.0,
flexibleSpace: FlexibleSpaceBar(
collapseMode: CollapseMode.pin,
background: Container(
color: Colors.blue,
padding: EdgeInsets.fromLTRB(5.0, 5.0, 5.0, 0),
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
IconButton(
padding: EdgeInsets.fromLTRB(8.0, 8.0, 25.0, 22.0),
constraints: BoxConstraints(),
onPressed: () {},
icon: Icon(
Icons.arrow_back,
size: 35.0,
color: Colors.white,
),
),
Padding(
padding: EdgeInsets.fromLTRB(5.0, 5.0, 5.0, 8.0),
child: Text(
'Text Reading Title'
overflow: TextOverflow.ellipsis,
style: TextStyle(
fontSize: 18,
color: Colors.white,
),
),
),
SizedBox(
width: 35.0,
),
],
),
],
),
),
),
),
SliverList(

[
