Xcode and Flutter Plugin: Could not find or use auto-linked framework 'Flutter'

Question

I'm running into an issue with archiving my app for the app store. Here are the pertinent facts:

I have an iOS app written in Objective-C, with cocoapods for libraries.
The app also has a sister project, a Flutter module that displays a screen inside the iOS app. I followed these instructions to get the module built: https://flutter.dev/docs/development/add-to-app/ios/project-setup#create-a-flutter-module
The app compiles fine in development mode - I can compile and run it on the simulator or on a device such as an iPhone.
When I try to archive it for the store, this happens:

Undefined symbols for architecture armv7:
  "_FlutterMethodNotImplemented", referenced from:
      ___47+[FLTPathProviderPlugin registerWithRegistrar:]_block_invoke in FLTPathProviderPlugin.o
  "_OBJC_CLASS_$_FlutterError", referenced from:
      objc-class-ref in FLTPathProviderPlugin.o
  "_OBJC_CLASS_$_FlutterMethodChannel", referenced from:
      objc-class-ref in FLTPathProviderPlugin.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Just to be clear, this compiles just fine for development - it is only when I switch to archiving it that the compilation fails. Your assistance is most appreciated!

I had this problem and spent all day trying to fix it.

This worked for me:

Delete the iOS folder in your flutter project
Run flutter create .
If you made any changes to your pod file, plists, etc. Update them now
Install your pods and run.
