fcast_sender_sdk

Flutter/Dart bindings for the FCast Sender SDK. Discover FCast and Google Cast (Chromecast) receivers on the local network and control playback.

The native (Rust) library is generated with flutter_rust_bridge and built & bundled via Dart's native assets build hook (hook/build.dart).

Supported platforms

Android, iOS, Linux, macOS, and Windows. Web is not supported — the SDK's TCP/TLS networking does not build for wasm.

Requirements

• rustup — the native build uses it to manage the Rust toolchain
• A Flutter/Dart SDK with native assets enabled:

  flutter config --enable-native-assets
  

Selecting protocols / features (fcast, chromecast)

The underlying fcast-sender-sdk crate exposes cargo features. This plugin forwards them (rust/Cargo.toml):

Default (all three) is used when you configure nothing.

A consuming app selects a subset by declaring native-assets user-defines in its own pubspec.yaml:

# app's pubspec.yaml  (workspace-root pubspec.yaml if you use a pub workspace)
hooks:
  user_defines:
    fcast_sender_sdk:
      features: [fcast]   # fcast-only build

Trimming features reduces the native binary size and the set of compiled dependencies.

Regenerating the bindings

The generated files (lib/src/rust/*.dart, rust/src/frb_generated.rs) are git-ignored and regenerated. Run this from anywhere in the monorepo after a fresh clone or after editing rust/src/api.rs:

cargo xtask flutter generate

The xtask ensures that flutter_rust_bridge_codegen is always the same version as the companion flutter package so the generated code can never be invalid at runtime.
