/// An annotation to specify that a method or class provides a new instance
/// each time it is requested.
///
/// This is typically used to indicate that the annotated binding should
/// not be a singleton and a new object is created for every injection.
///
/// Example:
/// ```dart
/// @module()
/// abstract class AppModule extends Module {
///   @instance()
///   Foo foo() => Foo();
/// }
/// ```
///
/// This will generate:
/// ```dart
/// final class $AppModule extends AppModule {
///   @override
///   void builder(Scope currentScope) {
///     bind<Foo>().toInstance(() => foo());
///   }
/// }
/// ```
// ignore: camel_case_types
final class instance {
  const instance();
