ExampleEmbedder was renamed at least a month ago, but the script output here is from a very recent version. How did you set up your build environment to get into this state?

<parent dir>
  ├─ flutter (from http://github.com/flutter/flutter)
  ├─ flutter-desktop-embedding (from https://github.com/google/flutter-desktop-embedding)
  └─ flutter_slides (from https://github.com/flutter/slideplayer)

I open ExampleEmbedder.xcodeproj in slideplayer project.

FDE is very explicitly not a stable API surface; an app build against an arbitrary version of it isn't going to work with new versions of FDE without updates (which that project doesn't appear to have had recently).

The README there gives hashes of Flutter and FDE versions that are known to work; if you want to try the project out you'll need to use those. (Or port their native code changes into a current version of FDE's example Runner).
