[scrollable_positioned_list] initialScrollIndex broken with shrinkWrap

[kulture-rob-snider]

Problem description

When using initialScrollIndex other than 0 in combination with shrinkWrap, the list is not rendered correctly.

Steps to reproduce

sample code

``` import 'package:flutter/material.dart'; import 'package:scrollable_positioned_list/scrollable_positioned_list.dart'; void main() { runApp( const ScrollablePositionedListExample(), ); } class ScrollablePositionedListExample extends StatelessWidget { const ScrollablePositionedListExample({Key? key}) : super(key: key); @override Widget build(BuildContext context) { return MaterialApp( title: 'ScrollablePositionedList Example', theme: ThemeData(primarySwatch: Colors.blue), home: Material( child: SafeArea( child: ScrollablePositionedList.separated( initialScrollIndex: 2, shrinkWrap: true, reverse: true, itemCount: 5, itemBuilder: (_, index) => ListTile(title: Text('$index')), separatorBuilder: (_, __) => const Divider(), ), ), ), ); } } ```

Expected behavior

I would expect that a continuous list is displayed with all items visible.

Actual behavior

• with reverse: true the list is split as if there was a Spacer() at the initialScrollIndex.
• with reverse: false the items before initialScrollIndex are given space, but do not appear

reverse: true


reverse: false
