flutter_js_bridger library

Flutter JS Bridger — Use any npm package in your Flutter/Dart projects.

Provides a seamless bridge between Dart and the JavaScript ecosystem. Install, load, and use any npm package directly from Dart with natural, idiomatic syntax.

Cross-platform: Works on Desktop (Node.js), Web (dart:js_interop), iOS/macOS (JavaScriptCore FFI), and Android (QuickJS FFI).

Quick Start (recommended — manifest-based)

# Terminal — manage packages once:
dart run flutter_js_bridger init
dart run flutter_js_bridger add lodash

import 'package:flutter_js_bridger/flutter_js_bridger.dart';

void main() async {
  final js = JsBridge();
  await js.initialize();  // reads js_bridger.json, verifies deps

  dynamic _ = await js.require('lodash');
  var chunks = await _.chunk([1, 2, 3, 4, 5], 2);
  print(chunks); // [[1, 2], [3, 4], [5]]

  await js.dispose();
}
