#What it is
Command-line tooling for teams running Unity and Flutter in the same repository: export the Unity project, sync it into the Flutter build, and keep the two in step across branches.
It was the first attempt at automating the build configuration that generated most of Flutter Unity Widget's issue volume. It handled the common path and left the awkward parts, meaning Gradle plugin versions, Podfile deployment targets and per-platform export layouts, to the README.
Game CLI is the current version of this idea, with the awkward parts included.
