dart_monty_native 0.6.1

Native plugin for dart_monty (replaces dart_monty_desktop). Pure Dart bindings for Monty — a restricted sandboxed Python interpreter built in Rust.

dart_monty_native

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

Live Demo | GitHub | Monty

This package is co-designed by human and AI — nearly all code is AI-generated.

Flutter plugin — native implementation of dart_monty using FFI. Runs the Monty Python interpreter in a background Isolate for non-blocking execution from Flutter apps on macOS, Linux, Windows, iOS, and Android.

Requires Flutter. This package is not intended for direct use. Import dart_monty instead — the federated plugin system selects this package automatically on native platforms.

How It Works

DartMontyNative registers itself as the MontyPlatform instance via Flutter's dartPluginClass mechanism. Execution runs in a background Isolate to keep the UI thread responsive, delegating to dart_monty_ffi for the actual FFI calls.

Bundled Binaries

This package vendors pre-built native libraries for supported platforms:

• macos/libdart_monty_native.dylib
• linux/libdart_monty_native.so

Usage

This package registers itself automatically. In your Flutter app, use the public API:

import 'package:dart_monty/dart_monty.dart';
import 'package:dart_monty_platform_interface/dart_monty_platform_interface.dart';

Future<void> main() async {
  // MontyPlatform.instance is set to MontyNative on desktop automatically.
  // MontyNative runs the interpreter in a background Isolate.
  final monty = MontyPlatform.instance;
  final result = await monty.run('2 + 2');
  print(result.value); // 4

  await monty.dispose();
}
