Proof-of-concept proving the Flutter/Rust bridge exit criterion from
docs/architecture/proof-of-concept-plan.md §2:
"Flutter can call Rust and receive event stream data."
The spike exposes one synchronous fallible command (greet) returning
a typed GreetResult / GreetError DTO, and one async event stream
(counter_stream) emitting typed CounterTick events. The Flutter app
demonstrates both flows on a Material 3 surface; the headless test
suite in test/poc_verification_test.dart exercises the same API
directly through dart:ffi.
Verified on 2026-05-13 (Linux desktop, Flutter 3.41.9 / Dart 3.11.5,
flutter_rust_bridge 2.12.0, Rust 1.95). All three tests pass:
- greet() returns typed result for valid input
- greet() surfaces typed error for empty input
- counterStream() delivers the expected event sequence
Authority: PoC plan §2, DEC-014 (typed Flutter/Rust bridge),
SAD-068, SDD-079, SysDes-049.
Naming note: the PoC plan lists this as flutter-rust-bridge-hello,
but Dart pubspec.yaml package names require underscores; the
directory uses underscores accordingly.
Not product code; not promoted into chanora_bridge.
Layout note: includes the full Flutter platform scaffold (android,
ios, macos, windows, web, linux). Only the Linux desktop target has
been built and verified.
Proof-of-concept proving the protocol-feasibility exit criterion from
docs/architecture/proof-of-concept-plan.md §2:
"Rust can connect to a compatible server/test double."
The spike opens a tsclientlib connection, waits for the BookEvents
state snapshot, subscribes to the server channel tree, prints
server metadata and the channel tree with client names, and
disconnects cleanly. Audio feature is disabled because audio is
covered by a separate PoC.
Verified on 2026-05-13 against cn.teamspeak.app (TeamSpeak 3 server
3.13.7); 36 channels and 5 online clients retrieved with full
UTF-8 (CJK) preservation. See
poc/tsclientlib-connect-spike/VERIFICATION.md for the captured run.
