warden_ffi_flutter

Flutter plugin that bundles the Warden native FFI library (the Veil bridge) so a Flutter app gets the threshold conditional-decryption gate with no Rust toolchain and no native build wiring. It wraps and re-exports the pure warden_ffi binding; its only job is to deliver the matching native library per platform.

⚠️ Preview / Phase-0 PoC. On a single-operator test federation the timing guarantee is not security — this gate gives condition-binding only. Not audited.

Use

dependencies:
  warden_ffi_flutter: 0.1.0-dev.1

import 'package:warden_ffi_flutter/warden_ffi_flutter.dart';

// The native library is bundled by this plugin, so no path is needed on device.
final warden = WardenFfi.load();

final id  = warden.conditionIdentity(conditionJson);
final env = warden.sealGated(conditionJson, masterPubHex, network, blobHex);
// …once the federation releases enough partials for this condition…
final dId  = warden.combine(partialsJson, id, fedJson);
final blob = warden.openGated(env, dId); // == the original blobHex

How the native library is delivered

Binaries are large and platform-specific, so they are not shipped inside this package. They're built once per version by warden CI and published as GitHub Release assets; this plugin downloads the matching set at build time:

• iOS — the podspec's prepare_command downloads the prebuilt dynamic WardenFfi.xcframework and CocoaPods embeds + signs it. dyld loads it at app launch, so WardenFfi.load() resolves the symbols via DynamicLibrary.process() — no -force_load, no Xcode wiring.
• Android — build.gradle downloads jniLibs/<abi>/libwarden_ffi.so and adds it as a jniLibs source set; Gradle bundles it into the APK and WardenFfi.load() resolves it via DynamicLibrary.open('libwarden_ffi.so').

The warden release tag the binaries come from is pinned in both files (warden_tag / WARDEN_NATIVE_TAG) and kept in lockstep with this package's version.

Desktop / tests

For host (desktop/CI) use, depend on the pure warden_ffi package directly and pass a dylib path to WardenFfi.load(path: …) — see its README. This plugin targets iOS + Android.
