Issue: ReorderableListView throws errors when containing only one draggable item
Labels: platform-android,framework,f: scrolling,has reproducible steps,P3,team-design,triaged-design,found in release: 3.13,found in release: 3.16

### Is there an existing issue for this?

- [X] I have searched the [existing issues](https://github.com/flutter/flutter/issues)
- [X] I have read the [guide to filing a bug](https://flutter.dev/docs/resources/bug-reports)

### Steps to reproduce

1. Create Column
2. Create Flexible Widget as child
3. Create ReorderableListView as child
4. Set shrinkWrap of ReorderableListView to true 
5. Set onReorder 
6. Set Children as ReorderableDragStartListener
7. Start run & debug on mobile android emulator (tested with Pixel 6 Pro API 29 and 34)
8. Observe that if one item gets added to the list, then dragged over the space / area of the shrinked ReorderableListView, errors get thrown around

### Expected results

Even if one item gets added to ReorderableListView with shrinkWrap set to true, the calculation of the area for reordering should still work, without throwing errors. It seems like shirnkWrap isn't working right.

### Actual results
