Either **download from the cache**:
```
nix-store -r /nix/store/sjiqk666k6y2m776806rk85v7xsaprcx-flatbuffers-25.12.19-2026-02-06-03fffb2 \
  --option binary-caches 'https://cache.nixos.org/ https://nixpkgs-update-cache.nix-community.org/' \
  --option trusted-public-keys '
  nixpkgs-update-cache.nix-community.org-1:U8d6wiQecHUPJFSqHN9GSSmNkmdiFW7GW7WNAnHW0SM=
  cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=
  '
```
(The nixpkgs-update cache is only trusted for this store-path realization.)
For the cached download to work, your user must be in the `trusted-users` list or you can use `sudo` since root is effectively trusted.

Or, **build yourself**:
```
nix-build -A flatbuffers https://github.com/r-ryantm/nixpkgs/archive/09172a3cd63d37cf0a70938c92eea63ac9366a43.tar.gz
```
Or:
```
nix build github:r-ryantm/nixpkgs/09172a3cd63d37cf0a70938c92eea63ac9366a43#flatbuffers
```

After you've downloaded or built it, look at the files and if there are any, run the binaries:
```
ls -la /nix/store/sjiqk666k6y2m776806rk85v7xsaprcx-flatbuffers-25.12.19-2026-02-06-03fffb2
ls -la /nix/store/sjiqk666k6y2m776806rk85v7xsaprcx-flatbuffers-25.12.19-2026-02-06-03fffb2/bin
```
