Ack Example Package

This package demonstrates both code-generation directions: schemas converted to immutable models with @AckInfer(), and hand-written classes converted to codec schemas with @AckModel(). Annotated examples declare both .ack.dart and .ack.g.dart parts.

Included examples

• Primitive typed schemas in lib/schema_types_primitives.dart
• Object schemas in lib/schema_types_simple.dart
• Discriminated schemas in lib/schema_types_discriminated.dart
• Built-in and custom codec schemas in lib/schema_types_transforms.dart
• Edge cases and strict resolution in lib/schema_types_edge_cases.dart
• Cross-schema object models in lib/pet.dart, lib/user_with_color.dart, and lib/additional_properties_example.dart
• Codecs (built-in and custom) in lib/codecs_example.dart
• Hand-written class-first models and sealed unions in lib/class_first_models.dart, including the required _$ClassAck mixin, AccountSchema.schema / wireSchema, and union facades backed by private codecs

Try both generation directions

The checked-in generated parts let you use the examples immediately:

import 'package:ack_example/class_first_models.dart';
import 'package:ack_example/schema_types_simple.dart';

void main() {
  final user = User.parse({'name': 'Ada', 'age': 36, 'active': true});
  print(user.name);

  final account = Account.fromJson({'display_name': 'Ada'});
  print(account.toJson()); // {'display_name': 'Ada', 'role': 'member'}
}
