// Hash Wallet: stub for the FFI bindings normally generated by ffigen from
// cw_mweb/android/src/main/jniLibs/arm64-v8a/libmweb.h.
//
// Upstream Cake only ships MWeb on iOS + Android — no Linux/macOS/Windows
// build of the Go-based mwebd daemon exists. Without this stub the Dart
// build fails on those platforms because cw_mweb/lib/mweb_ffi.dart imports
// MWebFlutter from this file at compile time.
//
// At runtime, attempting to use MWeb features will throw because
// DynamicLibrary.open(libPath) won't find a libmweb.so on desktop. That's
// fine — Litecoin's MWEB extension is a niche feature most users won't hit,
// and standard LTC sends/receives still work without it.
//
// To get real bindings (e.g. for an Android build): run ffigen against the
// libmweb.h header generated by `go build -buildmode=c-shared` in cw_mweb/go.
// See scripts/android/build_mwebd.sh for the canonical Android build.
