/// Marks a provider method or class so its instance is created only once and shared (singleton) for DI in CherryPick.
|
|
///
|
|
/// Use `@singleton()` on provider methods or classes in your DI module to ensure only one instance is ever created
|
|
/// and reused across the application's lifetime (or scope lifetime).
|
|
///
|
|
/// Example:
|
|
/// ```dart
|
|
/// import 'package:cherrypick_annotations/cherrypick_annotations.dart';
|
|
///
|
|
/// @module()
|
|
/// abstract class AppModule {
|
|
/// @singleton()
|
|
/// ApiClient createApi() => ApiClient();
|
|
/// }
|
|
/// ```
|
|
///
|
|
/// The generated code will ensure:
|
|
/// ```dart
|
|
/// bind<ApiClient>().toProvide(() => createApi()).singleton();
|
|
/// ```
|
|
///
|
|
/// See also: [@instance], [@provide], [@named]
