workaround is to put a SizedBox with height around Wrap, then it renders again

Triage Report

I was able to reproduce the issue using the provided code sample on the stable (3.29.3), stable (3.32.0) and master (3.33.0-1.0.pre.146) channels.

On master, the behavior is a bit different. the AlertDialog shows up but after interacting with the DropdownMenuButton, it breaks.

Tested on Android, iOS, Web, and macOS.

Replacing Wrap with Column / Row / OverflowBar doesn't create this issue.

The following assertion was thrown during performLayout():
The RenderPositionedBox class does not implement "computeDryBaseline".
If you are not writing your own RenderBox subclass, then this is not
your fault. Contact support: https://github.com/flutter/flutter/issues/new?template=02_bug.yml
