import 'package:meta/meta.dart';

/// Marks a class as injectable, enabling automatic field injection by CherryPick's code generator.
///
/// Use `@injectable()` on a class whose fields (marked with `@inject`) you want to be automatically injected from the DI [Scope].
/// When used together with code generation (see cherrypick_generator), a mixin will be generated to inject fields.
///
/// Example:
/// ```dart
/// import 'package:cherrypick_annotations/cherrypick_annotations.dart';
///
/// @injectable()
/// class ProfileScreen with _\$ProfileScreen {
///   @inject()
///   late final UserManager manager;
///
///   @inject()
///   @named('main')
///   late final ApiClient api;
/// }
///
/// // After running build_runner, call:
/// // profileScreen.injectFields();
/// ```
///
/// After running the generator, the mixin (`_\$ProfileScreen`) will be available to help auto-inject all [@inject] fields in your widget/service/controller.
