When trying to run the flutter examples, it throws the following error:

2021-08-25 10:03:08,360 DEBUG [rid_build::ffigen::run_ffigen] Running '"dart" "run" "ffigen" "--config" "/tmp/.tmpoThyRa/ffigen_config.yaml"' from: '"/home/marcos/Proyectos/ffi_demos/rid-examples/flutter/todo"'
thread 'main' panicked at 'Build failed: 'dart run ffigen' failed to run successfully
stderr: The Flutter SDK is not available. 
stdout: ', rid_build.rs:30:26

In my case the problem turned out to be that I use a version manager (FVM). Then I was able to solve it by simply modifying the FFIGEN_RUNNER value from dart to fvm dart in the file: id-build/src/ffigen/run_ffigen.rs

const FFIGEN_RUNNER: &str = "fvm dart";

I wonder if there is a way to include this case to avoid having to modify the code by hand.

The only option I see here is to allow devs to override the FFIGEN_RUNNER via a config. Let's keep this open, but I don't think it makes much sense to invest much work for now since you found a workaround. When creating the rid cli tool I'll make sure to make this configurable.

If you're running it on Linux and you don't mind making some aliases, you can add alias dart=fvm dart, which IMHO fvm should've done. Scripts should work without a hitch after.

Closing since this is an edge case and a workaround exists. Will be addressed for the CLI tool via a config option.
