ConfigurationProperty class final

Annotation used to bind externalized configuration properties from the Environment into a Dart object.

Supports nested property binding, where nested classes are automatically populated from environment values.

Example

@ConfigurationProperty(prefix: 'server')
class ServerConfig {
  late String host;
  late int port;

  late DatabaseConfig database;
}

class DatabaseConfig {
  late String url;
  late String username;
  late String password;
}

// application.yaml
// server:
//   host: localhost
//   port: 8080
//   database:
//     url: jdbc:postgresql://localhost:5432/app
//     username: admin
//     password: secret

JetLeaf automatically constructs and populates both ServerConfig and its nested DatabaseConfig.
