dart_monty_ffi 0.6.0

Native FFI backend for dart_monty, pure Dart bindings for Monty — a restricted sandboxed Python interpreter built in Rust.

dart_monty_ffi

Part of dart_monty — pure Dart bindings for Monty, a restricted, sandboxed Python interpreter built in Rust.

Live Demo | GitHub | Monty

Pure Dart native FFI implementation of dart_monty. Wraps the Rust libdart_monty_native shared library via dart:ffi, providing synchronous bindings to the Monty sandboxed Python interpreter.

This package has no Flutter dependency and can be used in CLI tools, server-side Dart, or any Dart project.

• Flutter apps should import dart_monty instead — the federated plugin selects the correct backend automatically.
• Pure Dart projects (CLI, server) can depend on this package directly to run Python via the native Rust library.

Architecture

Dart -> NativeBindingsFfi (dart:ffi)
  -> DynamicLibrary.open(libdart_monty_native)
    -> 17 extern "C" functions (Rust)

Key Classes

Class	Description
NativeBindings	Abstract interface over the 17 native C functions
NativeBindingsFfi	Concrete FFI implementation with pointer lifecycle management
MontyFfi	MontyPlatform implementation using NativeBindings
NativeLibraryLoader	Platform-aware library path resolution
