dartify<T> function

T dartify<T>(dynamic jsObject)

Returns Dart representation from JS Object.

Basic types (num, bool, String) are returned as-is. JS arrays are converted into List instances. JS objects are converted into Map instances. Both arrays and objects are traversed recursively converting nested values.

Converting JS objects always results in a Map<String, dynamic> meaning even if original object had an integer key set, it will be converted into a String. This is different from JS semantics where you are allowed to access a key by passing its int value, e.g. obj[1] would work in JS, but fail in Dart.

Implementation

T dartify<T>(dynamic jsObject) {
  if (_isBasicType(jsObject)) {
    return jsObject as T;
  }

  if (jsObject is List) {
    return jsObject.map(dartify).toList() as T;
  }

  var keys = objectKeys(jsObject);
  var result = <String, dynamic>{};
  for (var key in keys) {
    result[key] = dartify(js_util.getProperty(jsObject, key));
  }

  return result as T;
}
