I don't - I've never actually used flatbuffers. There are two pieces of code you'll want (if possible):
1. A `connect.Codec` implementation. I think it'd look almost the same as our Protobuf codec [0], but you'd use `FlatbuffersCodec.Marshal` and `FlatbuffersCodec.Unmarshal` (from github.com/google/flatbuffers/go). You _must_ have a `Codec`, but it looks like it should be pretty quick.
2. Ideally, you'd have a standalone program to parse your Flatbuffer schema and produce Connect code. The output would probably be very similar to `protoc-gen-connect-go`'s [1]. This isn't required, but it's a nice quality of life improvement (check out [1] to see the kind of conveniences it adds). With Protobuf, you'd do this via a `protoc` plugin and you wouldn't need to parse the schema yourself. From a quick look, I don't think `flatc` supports plugins
Read the rest
at all - so maybe you'd either skip this step or put in the effort to parse the schema yourself?

Also, thank you for making me stop and think about this in detail. I just pulled Flatbuffers out of a hat when I was writing that part of the docs and assumed that `flatc` supported plugins like `protoc`. Turns out that when you assume... I'm updating that portion of the documentation now :)
