The only thing I am not sure about is
https://docs.flutter.dev/deployment/flavors#plugin-configurations

This documentation talks about making changes to podfile. However, it is not clear at all how to make this change with multiple flavors or why it is needed.

No online tutorials talk about this either.

I was able to resolve the issue with this:

If anyone can document these changes in flavor documentation and explain the issue that would be appreciated. Should generated be in parent runner or child runner?

This link says to I was able to have it update again after setting it to the Generated.xcconfig file., ie, you need to make sure your flavor configuration is actually using that xcconfig. For it, see if this helps in your case or not.

/cc @leighajarett for visibility. Since you are actively working on improving flavors documentation and use cases in Flutter :)

For your reference: #8743 and #8743

What about cases where you have a pod file? What order should they be in? Or was the pod file missing something where it should already include the generated file?

Thanks for the update. I'll keep this issue open for documentation to answer the queries raised here:

#8743

In that screenshot your prod and staging targets are using the Generated.xcconfig base configuration (it's overriding the Pods- one you set at the project-level). Technically it should be Release.xcconfig but all that's doing is #includeing the Generated.xcconfig. As the docs say:

 Note: Your configurations should be based on your Debug.xconfig or Release.xcconfig file, not the Pods-Runner.xcconfigs. You can check this by expanding the configuration names.

Ideally we would have a screenshot of that in step 3 similar to the one linked: flutter/flutter#82183 (comment)

Should have linked it: https://docs.flutter.dev/deployment/flavors#creating-flavors-in-ios. The blue box has the note.

@jmagman
Can you explain this part of the docs? In particular if there is multiple flavors?
https://docs.flutter.dev/deployment/flavors#plugin-configurations

Example with paid and free flavors:

I'm going to move this to the website issue tracker since this is a request for improving that documentation.
