Dynamically convert a Dart 2 Map to a Javascript object

I was able to solve this problem by writing this function that converts a Map to js object.

import 'package:js/js_util.dart' as js;Object mapToJSObj(Map<dynamic,dynamic> a){  var object = js.newObject();  a.forEach((k, v) {    var key = k;    var value = v;    js.setProperty(object, key, value);  });  return object;}

A slightly modified version of the accepted answer, which also handles nested Maps. And I also added a solution for convering the other way: from a Javascript object to a Dart Map.

import 'package:js/js.dart';import 'package:js/js_util.dart';Object mapToJsObject(Map map){  var object = newObject();  map.forEach((k, v) {    if (v is Map) {      setProperty(object, k, mapToJsObject(v));    } else {      setProperty(object, k, v);    }  });  return object;}Map jsObjectToMap(dynamic jsObject) {  Map result = {};  List keys = _objectKeys(jsObject);  for (dynamic key in keys) {    dynamic value = getProperty(jsObject, key);    List nestedKeys = objectKeys(value);    if ((nestedKeys ?? []).isNotEmpty) {      //nested property      result[key] = jsObjectToMap(value);    } else {      result[key] = value;    }  }  return result;}List<String> objectKeys(dynamic jsObject) {  if (jsObject == null || jsObject is String || jsObject is num || jsObject is bool) return null;  return _objectKeys(jsObject);}@JS('Object.keys')external List<String> _objectKeys(jsObject);
