DataSource class

DataSource layer annotation - indicates data source components

This annotation is a specialization of @Component for classes that provide direct data access functionality, such as API clients, database connections, or external service integrations.

DataSources are typically the lowest level in the data layer, handling the actual data retrieval and storage mechanisms.

Example:

@DataSource()
class UserApiDataSource {
  Future<Map<String, dynamic>> fetchUser(String id) async {
    // API call logic here
    return await httpClient.get('/users/$id');
  }
}

@DataSource()
class UserLocalDataSource {
  Future<Map<String, dynamic>?> getUserFromCache(String id) async {
    // Local storage logic here
    return await localStorage.get('user_$id');
  }
}
