iroh_dart monorepo

Dart + Flutter bindings for iroh 1.0 — peer-to-peer QUIC networking (endpoints, connections, streams, relays, address lookup) over the iroh Rust core via flutter_rust_bridge + dart:ffi.

This is a pub workspace (Melos) with two published packages that share one Rust crate:

Package	What	Platforms
packages/iroh_quic	Pure-Dart binding. dart run / CLI / server. Loads a signed prebuilt native lib (dart run iroh_quic:setup) or builds from source.	Linux · macOS · Windows
packages/iroh_flutter	Flutter plugin. Builds the native core into your app via cargokit; re-exports the full iroh_quic API.	Android · iOS · macOS · Linux · Windows

The Dart API is identical across both — iroh_flutter just adds the per-platform native build for Flutter apps. Pick iroh_quic for a desktop/CLI Dart program, iroh_flutter for a Flutter app.

Layout

pubspec.yaml                      workspace root + Melos config (no melos.yaml)
tool/sync_native.sh               vendors the shared crate into the plugin (cargokit needs it co-located)
packages/
  iroh_quic/                      pure-Dart binding (publishable)
    rust/                         the owned `irohdart_ffi` crate (canonical source of truth)
    lib/  bin/  test/  tool/
  iroh_flutter/                   Flutter plugin (publishable)
    android/ ios/ macos/ linux/ windows/   cargokit native build per platform
    cargokit/                     vendored build glue
    rust/                         generated copy of the crate (gitignored; from sync_native.sh)
    example/                      example app + on-device integration tests

Develop

dart pub global activate melos          # optional; plain pub get also works
flutter pub get                         # resolves the whole workspace
bash tool/sync_native.sh                # vendor the crate into iroh_flutter (also run by `melos bootstrap`)

# Pure-Dart gate (Rust + Dart tests for iroh_quic):
./packages/iroh_quic/tool/check.sh

# Flutter plugin (build the example for any platform):
cd packages/iroh_flutter/example && flutter run -d macos   # or an iOS sim / Android emulator

The single source of truth for the Rust crate is packages/iroh_quic/rust. cargokit requires the crate beside the plugin, so tool/sync_native.sh mirrors it into packages/iroh_flutter/rust (which is gitignored and re-vendored before publishing).

Native library distribution

• iroh_quic (desktop): signed prebuilt cdylibs are built per release, Ed25519-signed, and attached to the GitHub Release; dart run iroh_quic:setup downloads + verifies one. No Rust toolchain needed. Or dart run iroh_quic:build to compile from source.
• iroh_flutter (mobile/desktop): cargokit compiles the crate during the consumer's app build (no download); force cargokit_options.yaml: use_precompiled_binaries: false to always build from source.
