Create an instance of an object from a String in Dart?

Question

How would I do the Dart equivalent of this Java code?

Class c = Class.forName(\"mypackage.MyClass\");
Const

Using built_mirrors you can do it next way:

library my_lib;

import 'package:built_mirrors/built_mirrors.dart';

part 'my_lib.g.dart';

@reflectable
class MyClass {

  String myAttribute;

  MyClass(this.myAttribute);
}

main() {
  _initMirrors();

  ClassMirror cm = reflectType(MyClass);

  var o = cm.constructors[''](['MyAttributeValue']);

  print("o.myAttribute: ${o.myattribute}");
}
