** UPDATE: After a day of playing with this I found a fix within 10 minutes of this post!
Problem with flutter_form_builder version. Set to this version. Worked for me with code from the download.
flutter_form_builder: ^3.14.0-alpha.2
*** End Update ***
First let me say this tutorial has the best look/feel of any tutorial I’ve followed (both free and paid)! The work you put into this project shows. Unfortunately I have a similar issues posted above by colesluggett. From the start after downloading and PubGet the app errors. I have updated the form builder as Kevin suggested and further updated to latest available. I cleaned, doctored, removed Podfile.lock and had it rebuild. Continues to error out

This can cause issues if your application depends on plugins that do not support iOS.
See https://flutter.dev/docs/development/packages-and-plugins/developing-packages#plugin-platforms for details.
If you have local Podfile edits you would like to keep, see https://github.com/flutter/flutter/issues/45197 for instructions.
To regenerate the Podfile, run:
rm ios/Podfile
