Reorderable ListView retains "Item Spacing" setting, but hides it and makes it impossible to change

[prossm]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

(See Loom video below)
If a ListView has Item Spacing set and then is switched to "Reorderable", it looks as though there is no item spacing set, and yet the item spacing is retained and there's no way to change it with out switching Reorderable off, deleting the item spacing, then switching Reorderable back on.

Expected Behavior

Item Spacing should be actually deleted when "Reorderable" is toggled on for a ListView. Either that, or it should be editable even after Reorderable is set. But the former will be better at preventing headaches because of a bug preventing you from running the app in Test Mode.

Steps to Reproduce

My actual steps:

1. Use the AI feature to generate a page with a list of items that are reorderable
2. Move forward with that UI in your design system
3. The AI will generate a nice UI, but the list is not actually set to reorderable.
4. Connect up necessary data to make the ListView work
5. In the ListView, check the box for "Reorderable."
6. Try to test the app. The error prevents you (because the AI already set item spacing before you switched it to reorderable, and you didn't notice, so you have to toggle Reorderable off, delete the item spacing, then toggle Reorderable back on)

Steps without AI:

1. Create a new page
2. Add a ListView component to the page
3. Hook up the ListView to some data, displaying items in a column
4. Set the item spacing for the ListView to 12
5. Toggle the ListView to be "Reorderable"
6. Try to test the app. The error prevents you.
