cratestack_cbor 0.8.3

Native CBOR codec for CrateStack Dart/Flutter: flutter_rust_bridge (native, vendored) and wasm-bindgen (web, vendored), mirroring @cratestack/cbor conditional exports for JS.

0.8.0

• Initial package structure (cratestack#563). One uniform CratestackCborCodec API, auto-selected per platform:
  • Native: flutter_rust_bridge over a vendored prebuilt library. This release vendors Linux x86_64 and Android (arm64-v8a, x86_64, armeabi-v7a) — the remaining platform matrix (iOS, macOS, Windows, Linux arm64) is follow-up work.
  • Web: the existing cratestack-cbor-wasm wasm-bindgen artifact, vendored and loaded via dart:js_interop.
• Not yet published to pub.dev — see README.md.
• Flutter app integration, proven by real builds (cratestack#563):
  • Linux: a Flutter FFI plugin (linux/CMakeLists.txt) bundles the vendored .so into a real flutter build linux app, instead of the cargokit build-Rust-from-source pattern most flutter_rust_bridge plugins use.
  • Android: a Flutter FFI plugin (android/build.gradle) packages the vendored per-ABI .so files into the APK via the standard jniLibs mechanism — no CMake/NDK invocation at consumer build time. Verified by a real flutter build apk, per-ABI presence assertion, and a real install-and-run on an Android emulator round-tripping CBOR.
  • Web: pubspec.yaml's flutter: assets: vendors the .js/.wasm pair so a release flutter build web actually ships them; the web loader now tries both the dev-server and release asset URL conventions.
  • example/: a minimal Flutter app exercising the codec, verified with real flutter build linux/flutter build web/flutter build apk builds — see just cbor-example-verify and just cbor-example-verify-android.
