Compilation errors if flutter module with realm linked to native iOS app

[TooComplicatedBye]

What happened?

I have a native iOS app with a flutter module. (Path to the flutter module is $PROJECT_DIR/TargetA/FlutterModule) When I add realm to the flutter module and try to compile the whole app I get this error:
PhaseScriptExecution [CP-User]\ Download\ Realm\ Flutter\ iOS\ Binaries

/Users/user/Library/Developer/Xcode/DerivedData/MyProject-croqsfsonryeywhahmmyelbgulpt/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/realm.build/Script-8CDC23D80A80F3E753C4D0E74C40DA89.sh: line 2: /Users/user/myproject-ios/Pods/../Flutter/flutter_export_environment.sh: No such file or directory Command PhaseScriptExecution failed with a nonzero exit code

If I fix the path manually in Pods.xcodeproj(Target: realm) then I get this error:
Undefined symbols for architecture x86_64: "_OBJC_CLASS_$_RealmPlugin", referenced from: objc-class-ref in FlutterPluginRegistrant(GeneratedPluginRegistrant.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Repro steps

Hi @TooComplicatedBye!
We managed to reproduce the issue that you have reported.
We are looking for solution and we will write here later.
Thank you for reporting this issue!

Hi @TooComplicatedBye!
We will try to find a way to fix the paths, but it will take time. Meanwhile you can copy this file from flutter module /flutter_module/.ios/Flutter/flutter_export_environment.sh into the native app Flutter folder /myproject-ios/Flutter/flutter_export_environment.sh. On this way you won't need to change the project file each time after running pod install
The second error is interesting. Do you think it can be caused of changing the project file? Please check if this will help: https://stackoverflow.com/a/61806331

I had a similar error when running pod install

[!] /bin/bash -c 
set -e
$PROJECT_DIR/Flutter/flutter_export_environment.sh; cd "$FLUTTER_APPLICATION_PATH"; "$FLUTTER_ROOT"/bin/dart run realm install --target-os-type ios --flavor flutter

/bin/bash: line 2: /Flutter/flutter_export_environment.sh: No such file or directory

Tweaking the realm.podspec scripts resolved the error above:

  s.prepare_command           = '#{project_dir}/Flutter/flutter_export_environment.sh; cd "$FLUTTER_APPLICATION_PATH"; "$FLUTTER_ROOT"/bin/dart run realm install --target-os-type ios --flavor flutter'
  s.script_phases             = [

                                  #Use --debug to debug the install command
                                  :script => '$PROJECT_DIR/../Flutter/flutter_export_environment.sh; cd "$FLUTTER_APPLICATION_PATH"; "$FLUTTER_ROOT\"/bin/dart run realm install --target-os-type ios --flavor flutter',
