   Simple workaround that worked for me for some plugins:
   do not embed frameworks produced by Flutter for which we have the Multiple commands produce ... issue.

   For the sample code above, it means that we need to remove some frameworks from the Frameworks, Libraries, and Embedded Content section of the General target tab: Datadog.xcframework, Sentry.xcframework and SentryPrivate.xcframework. It worked for me previously for some plugins, for instance, if I have just sentry without datadog, it will work. Unfortunately, with the datadog and this workaround, we have multiple Undefined symbol issues:
   Build IOSUsingPrebuiltModule_2023-07-09T10-26-54.txt.
   This was also reported in the DataDog repo: DataDog/dd-sdk-flutter#443

   I believe this can't be a DataDogSdk issue, because all is working as expected using Option A. Probably it has smth to do with the fact that datadog_flutter_plugin.xcframework is static.

   Thanks for the detailed report. I was able to replicate the reported behavior using the code sample and steps to replicate provided.

   I also encountered this issue.
   Is there an ETA on when it will be fixed?

   I see that --no-plugins has been mentioned as a potential fix. Does this include not building any custom flutter plugins used in the project as well? If so, how can we build a flutter plugin separately from the main flutter project, since any native Pod dependencies are defined in the main project's Podfile?

   Also, is there a way to define a custom Pod dependency only for a given flutter plugin?
   It can be defined for the main flutter project with something like this:

   target "Runner" do
     pod "CustomPod", git: "<url to git repo hosting the pod>"
   end
   

   But is there a way to define it only for a specific flutter plugin?

    Hello @nasko25,

    My solution was:

    App and Flutter

    1. generated te App.xcframework and Flutter.xcframework using o comand flutter build ios-framweork;
    2. and I created a pod for each;
    3. Finally, generate a tar.gz

    For example the app.podspec:

    Pod::Spec.new do |spec|
      spec.name         = "app_flutter"
      spec.version      = "0.0.1"
      spec.summary      = "Flutter module for My App"
      spec.description  = <<-DESC
        Flutter module for My App
                        DESC
      spec.homepage     = "your-urlr"
      spec.license      = { :type => "MIT", :text => "Free" }
      spec.author       = { "Arthur Monteiro" => "[email protected]" }
      spec.platform     = :ios, "12.0"
      spec.source       = { :http => "file://" + __dir__ + "/app.tar.gz" }
      spec.vendored_frameworks = 'App.xcframework'
      spec.requires_arc = true
      spec.static_framework = true
    

    So in the podfile you can just add this podspec.

    pod "app_flutter", ...
    
    

    Plugins

    Whene you do the flutter pub get, a flutter-plugins-dependencies is generated with all the plugins necessary to run your flutter module. Also, in .ios/Flutter has a folder called FlutterPluginRegistrant with all dependencies.

    Basically you can add the FlutterPluginRegistrant pod in your podfile and use a private cocoapods repo (Ex. Jfrog Artifactory) with the pods. Maybe you can use git too.

    For example, my app has geolocator and maps. So the ios plugins in the FlutterPluginRegistrant I uploaded all to Jfrog.

    In my case I use the Jfrog and works fine.

    Example: Podfile

    plugin 'cocoapods-art', :sources => [
    'artifactory-ios'
    ]
    
      pod 'app_flutter', '2.2.0' # my module pod in Jfrog
      pod 'Flutter', '3.16.2' # the flutter version used to generated de app framework (needs to be the same)
      pod 'FlutterPluginRegistrant', '2.2.0' # my version of FlutterPluginRegistrant in Jfrog.

    @4rthurmonteiro have you written about how you did it?
    I am trying what you have suggested here, but I am stuck at the point where you are asking to create a pod lib for each dependency under /ios/.symlinks/plugin_name/ios

    Basically you can add the FlutterPluginRegistrant pod in your podfile and use a private cocoapods repo (Ex. Jfrog
    Artifactory) with the pods. Maybe you can use git too.

    We have run into the exact same issue with the Add to App approach via Option B, we chose option B as our project is solely SPM, we do not want to integrate Cocoapods, it is at end of life.
    Our native app has Datadog SDK in it, and we would also like to integrate Datadog SDK on the flutter side, all workarounds described above are not an option for a project that solely uses SPM. This would happen also with other SDK's such as Firebase.
    Are there any known solutions for SPM? If not, is there work being done around this, if so is there an ETA?

    I've found these #146957 and DataDog/dd-sdk-flutter#443 which outlines exactly the same issue.
    It is not really acceptable that even defined in the limitations is to link via podspec, which brings Cocoapods back into the picture, https://docs.flutter.dev/add-to-app/ios/project-setup#method-b-limits
