dart_monty 0.120.1

Script your Dart/Flutter app with sandboxed Python — runtime extensions, Flutter glue, and FFI/WASM asset loading on top of dart_monty_core.

dart_monty

dart_monty runs restricted Python from Dart and Flutter on native and web platforms. It adds stateful runtimes, Dart host functions, extensions, event streams, and OS-call policy to the pool and session primitives supplied by dart_monty_core.

Installation

dart pub add dart_monty

Or add to pubspec.yaml:

dependencies:
  dart_monty: ^0.120.1

Quick start

import 'package:dart_monty/dart_monty.dart';

Future<void> main() async {
  final runtime = await MontyRuntime.start();
  try {
    await runtime.execute('x = 41').result;
    final value = await runtime.execute('x + 1').result;
    print(value.dartValue); // 42
  } finally {
    await runtime.dispose();
  }
}

See Choosing an API for the runtime and direct session tradeoffs.

Platform support

The Dart VM and Flutter native targets use the prebuilt native worker that dart_monty_core downloads from its GitHub release at build time. Browser targets need core's Web Worker and WASM assets plus cross-origin isolation headers. See Installation and Deployment and Bundling for setup.
