## Changelog
# 0.14.0

- Stable null safety release
- removed `@nullable`.
  Instead of:
  ```dart
  factory Example({@nullable int a}) = _Example;
  ```
  Do:
  ```dart
  factory Example({int? a}) = _Example;
  ```
- removed `@late`.
  Instead of:

  ```dart
  abstract class Person with _$Person {
    factory Person({
      required String firstName,
      required String lastName,
    }) = _Person;

    @late
    String get fullName => '$firstName $lastName';
  }
  ```

  Do:

  ```dart
  abstract class Person with _$Person {
  Person._();
  factory Person({
    required String firstName,
    required String lastName,
  }) = _Person;

  late final fullName = '$firstName $lastName';
  }
  ```

# 0.12.0

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

  ```dart
  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.

# 0.11.0

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

  ```dart
  @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;
  }
  ```
