freezed_annotation

Added when/map back

• Breaking removed when/map related options

• Require json_annotation ^4.8.0

• Stop using JsonKey(ignore: true) in favour of JsonKey(includeFromJson: false, includeToJson: false) (thanks to @lrsvmb)

• Require Dart >=3.0.0
• Support latest collection

• The generic type of @With/@Implements now defaults to Object? instead of dynamic
• Allow enabling/disabling all when/map variants at once (thanks to @gaetschwartz)

• Re-introduced @With.fromString and @Implements.fromString to allow unions to implement generic types. (thanks to @rorystephenson)

• Add support for de/serializing generic Freezed classes (Thanks to @TimWhiting)

– fix: build.yaml decoding crash

• Fixed a bug where the generated when/map methods were potentially invalid when using default values
• Fixed a bug where when/map methods were generated even when not necessary

• Breaking: freezed_annotation no-longer exports the entire package:collection

• Breaking Removed @Freezed(maybeMap: ) & @Freezed(maybeWhen: ) in favor of a separate:

  @Freezed(map: FreezedMap(...), when: FreezedWhenOptions(...))
  

• Feat: Add screaming snake union case type (#617) (thanks to @zbarbuto)

• Added @unfreezed as a variant to @freezed, for mutable classes

Added support for disabling the generation of maybeMap/maybeWhen (thanks to @Lyokone)

freezed_annotation is now stable

• Breaking Changed the syntax for @With and @Implements to use a generic annotation. Before:

  @With(MyClass)
  @With.fromString('Generic<int>')
  

  After:

  @With<MyClass>()
  @With<Generic<int>>()
  

Upgraded to support last json_annotation version

• Added the ability to specify a fallback constructor when deserializing unions (thanks to @Brazol)

• Added the ability to customise the JSON value of a union. See https://github.com/rrousselGit/freezed#fromjson---classes-with-multiple-constructors for more information (Thanks to @ookami-kb)

• Stable null safety release

• removed @nullable. Instead of:

  factory Example({@nullable int a}) = _Example;
  

  Do:

  factory Example({int? a}) = _Example;
  

• removed @late. Instead of:

  abstract class Person with _$Person {
    factory Person({
      required String firstName,
      required String lastName,
    }) = _Person;
  
    @late
    String get fullName => '$firstName $lastName';
  }
  

  Do:

  abstract class Person with _$Person {
  Person._();
  factory Person({
    required String firstName,
    required String lastName,
  }) = _Person;
  
  late final fullName = '$firstName $lastName';
  }
  

• Migrated to null safety

• removed @nullable. Instead of:

  factory Example({@nullable int a}) = _Example;
  

  Do:

  factory Example({int? a}) = _Example;
  

• removed @late. Instead of:

  abstract class Person with _$Person {
    factory Person({
      required String firstName,
      required String lastName,
    }) = _Person;
  
    @late
    String get fullName => '$firstName $lastName';
  }
  

  Do:

  abstract class Person with _$Person {
  Person._();
  factory Person({
    required String firstName,
    required String lastName,
  }) = _Person;
  
  late final fullName = '$firstName $lastName';
  }
  

• Added Assert decorator to generate assert(...) statements on Freezed classes:

  abstract class Person with _$Person {
    @Assert('name.trim().isNotEmpty', 'name cannot be empty')
    @Assert('age >= 0')
    factory Person({
      String name,
      int age,
    }) = _Person;
  }
  

• Added a way to customize the de/serialization of union types using the @Freezed(unionKey: 'my-key') decorator.

  See also https://github.com/rrousselGit/freezed#fromjson---classes-with-multiple-constructors

• Added @With and @Implements decorators to allow only a specific constructor of a union type to implement an interface:

  @freezed
  abstract class Example with _$Example {
    const factory Example.person(String name, int age) = Person;
  
    @Implements(GeographicArea)
    const factory Example.city(String name, int population) = City;
  }
  

  Thanks to @long1eu~
