CamelCaseNamingStrategy class

Leaves field names unchanged (camelCase).

This is the default Dart naming strategy where JSON field names are kept the same as Dart field names. Use this strategy when your JSON API already uses camelCase or when you want to preserve the exact field names without transformation.

Identity Transformation:

  • camelCase to camelCase: No changes applied
  • camelCase from camelCase: No changes applied

Examples:

final strategy = CamelCaseNamingStrategy();

// Both directions preserve the original name
strategy.toJsonName('userName');        // 'userName'
strategy.toJsonName('HTTPRequest');     // 'HTTPRequest'
strategy.toJsonName('userId');          // 'userId'
strategy.toJsonName('XMLParser');       // 'XMLParser'
strategy.toJsonName('createdAt');       // 'createdAt'

strategy.toDartName('userName');        // 'userName'
strategy.toDartName('HTTPRequest');     // 'HTTPRequest'
strategy.toDartName('userId');          // 'userId'
strategy.toDartName('XMLParser');       // 'XMLParser'
strategy.toDartName('createdAt');       // 'createdAt'

Usage with JSON Serialization:

@Serializable(namingStrategy: CamelCaseNamingStrategy())
class User {
  final String firstName;
  final String lastName;
  final DateTime createdAt;
  final bool isActive;

  User(this.firstName, this.lastName, this.createdAt, this.isActive);
}

// Serializes to: 
// {
//   "firstName": "John",
//   "lastName": "Doe", 
//   "createdAt": "2023-01-01T10:00:00Z",
//   "isActive": true
// }

When to Use:

  • When working with JavaScript/TypeScript APIs that use camelCase
  • When the JSON schema matches your Dart class structure exactly
  • When you want maximum performance (no string transformations)
  • As a base class for composite naming strategies

Performance:

This strategy has minimal overhead since it performs no string transformations, making it the most performant option.
