In my project, I am using the flutter_google_places_sdk but I needed to modify certain things in its interface, so I forked the repository in Github, and I added a dependency override in my pubspec.yaml to point to my own Github repository for this specific dependency.
The problem is that this package uses freezed a lot to generate some files, and when I run flutter pub run build_runner build in my project, it doesn't seem to do anything for dependencies.
I even tried to add dependencies to freezed and freezed_annotation in my own project, hoping that it would signal build_runner to look for annotations in dependencies too, but it doesn't work either.
I am guessing that when you publish a package, it publishes generated files as well, but I don't want to publish this plugin, just use it for myself. What is the proper way to integrate this kind of dependency.
NB: After adding freezed-generated files to my fork of flutter_google_places_sdk as suggested by the chosen solution, I still had the following exception at runtime when calling fetchPlace, which I did not modify whatsoever, so it seems there might be an issue with the generated files.

You have to commit auto generated code in you forked repository by avoid in .gitignore.
I created PR here for your forked repo.
You can generate a code by running command flutter pub run build_runner build in that flutter_google_places_sdk_platform_interface folder manually.
