- Android: Dart FFI → Go c-shared (.so) in jniLibs (arm64-v8a + x86_64) - Linux: Dart FFI → Go c-shared (.so) via Docker cross-compilation (amd64) - Dart API: TsnetFlutter uses MethodChannel on iOS/macOS, FFI on Android/Linux - Add ffi package dependency for native function bindings - Build script: ./build_go.sh [ios|macos|android|linux|apple|all] - Android RegisterInterfaceGetter to bypass netlink CAP_NET_ADMIN restriction - Make TailscaleStart() idempotent and add GODEBUG=netdns=go for Android Known: Android tsnet tunnel blocked by Go stdlib net.Interfaces() netlink call — local gRPC works, Tailscale fallback needs libtailscale integration.
