freezed_annotation 0.12.0

freezed_annotation: ^0.12.0 copied to clipboard

• 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;
  }
