I'm making a Flutter plugin which must support macOS. However, when I want to create a plugin and run the plugin in the example app (even when I haven't edited the by Flutter generated code), Xcode throws the following error.

Unable to load contents of the file list: '/Users/admin/../example/macos/ephemeral/FlutterInputs.xcfilelist'

Unable to load contents of the file list: '/Users/admin/../example/macos/ephemeral/FlutterOutputs.xcfilelist'

This is my Flutter doctor:

I found another solution: Run the flutter build command flutter build macos before build in Xcode, then these input/out files appears.

  • FlutterInputs.xcfilelist
  • FlutterOutputs.xcfilelist

I solved this issue. When I created a Flutter Plugin these files weren't created. But when I created a Flutter Project these files where. When I copy/pasted those files to my plugin, the project build successfully!
