Description
Steps to reproduce
- Clone https://github.com/banool/auslan_dictionary

flutter run
Actual results
I can't build or run the ios build. The Android version of the app builds fine (as you can see from the CI in the PR above).
I have tried everything I've read online, various hacks with Podfile to set the target IOS deployment target (of the app and its dependencies, and I've tried many different versions like 12, 13, 16, etc), exclude simulation targets, etc. I have tried reinstalling flutter from scratch, I've tried the latest stable and main versions of flutter. I confirmed that the build settings in Xcode look correct (correct order, "for install builds only" unticked). I have reinstalled various versions of ruby, cocoapods, XCode, etc. I've cleaned every cache I can find in every permutation. I have tried deleting the ios folder and regenerating it. Deleting various generated files in the ios/Flutter directory. Pretty much anything that pops up from searching for this error on Google, you name it (definitely everything here and in a few other posts: https://stackoverflow.com/q/64973346/3846032). Even things that I wouldn't expect to work, like building using the Flutter extension from Android studio.
I have updated every dependency to the latest, including across major version boundaries, and transitively via that dictionarylib dep.
The error message tends to change, but I think it's related to any dependency that requires a platform integration (so some pod gets installed), e.g. sqflite, http_proxy, the splash page package, device_info_plus, package_info_plus, etc.
Worth noting that this app used to build fine, but is now failing on the latest version of Flutter / XCode / etc. I can't quite tell which thing broke it.

The verbose output is too long for an issue, you can find it in this gist: https://gist.github.com/banool/32c02eaf030a56d8477be5697acb0260.
