A Dart package that generates JSON serialization and deserialization code for Dart classes via annotations like @JsonSerializable and @JsonKey, using the Dart Build System (build_runner). It also includes _annotation for annotations, checked_yaml for better YAML decoding errors, and JsonLiteral/JsonEnum support.
Use cases
- generate fromJson/toJson code for Dart classes
- serialize and deserialize models to JSON in Flutter apps
- customize JSON field names and defaults with annotations
- generate JSON Schema from Dart classes
- handle enum serialization to JSON values
- load JSON files as Dart literals at build time
- decode YAML with helpful error messages
When to avoid
- your project is not Dart/Flutter
- you prefer runtime reflection-based serialization
- you need serialization formats other than JSON/YAML
- you cannot use build_runner code generation in your workflow
