Is there any option to dynamically create instance of class?

[asstet]

Hey, there's the question – could I create class instance if I have string variable which contains its name?
For example, i have
var className = 'DocumentsList';,
could I do something like this
var docListWidget = createInstance(className[, params]);

There is currently no such thing in Dart.
You could create a map from strings to factory methods like

var factories = <String, Object Function()>{'Foo', () => new Foo(), 'Bar', () => new Bar()};

String name = 'Foo';
Object instance = factories[name]();

Currently you can also:

T? createInstanceOf<T>() {
  final factories = <Type, T Function()>{
    Foo: () => Foo() as T, 
    Bar: () => Bar() as T,
  };
  
  final createInstance = factories[T];

  return createInstance?.call(); // Same as createInstance() but null safety
}
