import 'package:singleton_macro/singleton_macro.dart';

@Singleton()
class MySingletonClass {
String name = "foo";
}

void main() {
final instance1 = MySingletonClass();
print(instance1.name); // Output: foo

final instance2 = MySingletonClass();
instance2.name = "bar";
print(instance1.name); // Output: bar
