Improved serialization consistency and equality handling.

4.2.1 #

Performance improvements.

4.2.0 #

Added custom typedef for mapping fields to resolve naming conflict.
Deprecated creating and linking custom MapperContainers. If you are affected by this see https://github.com/schultek/dart_mappable/issues/159.

4.1.0 #

Added support for shallow encoding a class:
- MyClassMapper.ensureInitialized().encodeMap<MyClass>(myClass, EncodingOptions(shallow: true))
Correctly escape $ in class names.
Added option to use unordered list equality with iterables:
- IterableMapper.equalityMode = IterableEqualityMode.unordered

4.0.1 #

Added support for generic typed parameters for deep copyWith.

4.0.0 #

Require sdk: >=3.0.0.
Added support for Records.
- Fields of a class can now be any record type.
- You can annotate toplevel record typedefs:
```
  @MappableRecord()
  typedef Coordinates = ({double latitude, double longitude});
```
For a more detailed usage see the documentation.

3.3.0 #

Make enum encoding explicitly typed.
Update analyzer to '>=5.11.0 <7.0.0'

3.2.3 #

Respect keys and hooks for annotated getters.

3.2.2 #

Handle even more cases for generic subclassing.

3.2.1 #

Handle bounded nested type parameters in subclasses.

3.2.0 #

Added support for annotating getters with @MappableField, which will then be included in the encoding, equality checks, and stringification of that class.

3.1.2 #

Fixed bug with broken mapper generation.

3.1.1 #

Fixed supporting expressions in @MappableClass.includeCustomMappers.

3.1.0 #

Fixed error when using non-literal values in @MappableValue().

The builder now respects basic initializer expressions of a constructor. This makes it possible to do field renaming or assigning to private fields without requiring an additional getter matching the parameter.

The following is now supported out of the box:

class MyClass {
  MyClass(int value, {String? name}) 
      // Effectively renaming 'value' to 'data'.
    : data = value,
      // Assigning to a private field + having a null fallback.
      _name = name ?? 'Unnamed';

  final int value;
  final String _name;

Fixed encoding of a map now returns a Map<String, dynamic> where possible (instead of a Map<dynamic, dynamic>)

3.0.2 #

Fixed generic decoding when using generic superclass.
Fixed unknown-type bug for serialized non-constructor fields.

3.0.1 #

Fixed bug with undetermined includeSubClasses.

3.0.0 #

Breaking: Generated mappers no longer have a .container property. This was removed in favor of the new MapperContainer.globals container.
```
// Instead of this:
var value = MyClassMapper.container.fromValue(...);
// Do this:
var value = MapperContainer.globals.fromValue(...);
```
Mapper initialization and usage is now simplified to the following:
1. When used explicitly (e.g. through MyClassMapper.fromMap or myClass.toMap()) no additional initialization is needed.
2. When used implicitly (through a generic type e.g. MapperContainer.globals.fromMap<MyClass>()) the mapper needs to be initialized once before being used with MyClassMapper.ensureInitialized().
Breaking: Changed internal mapper implementation which causes any custom mapper to break.
- Removed MapperElementBase class.
- Added MappingContext being passed to mapper methods.
See docs on how to use custom mappers in v3.
Breaking: Removed @MappableLib.createCombinedContainer in favor of @MappableLib.generateInitializerForScope.

Instead of generating a new container, v3 generates an initialization function for all mappers. Use it early on in your application:
```
@MappableLib(generateInitializerForScope: InitializerScope.package)
library main;
  
import 'main.init.dart';
  
void main() {
  initializeMappers();
  ...
}
```
Breaking: Improved support and features for .copyWith.
- Copy-With now supports classes that implement multiple interfaces.
- Renamed .copyWith.apply() method to .copyWith.$update().
- Added .copyWith.$merge() and .copyWith.$delta().
You can now use .copyWith with either an existing instance using .$merge or a map of values using .$delta.
```
@MappableClass()
class A with AMappable {
  A(this.a, this.b);
    
  int? a;
  int? b;
}
  
void main() {
  var a = A(1, null);
    
  var c = a.copyWith.$merge(A(null, 2));
  assert(c == A(1, 2));
  
  var d = a.copyWith.$delta({'b': 2});
  assert(d == A(1, 2));
}
```

Breaking: Removed CheckTypesHook in favor of discriminator functions.

You can now use a custom predicate function as the discriminatorValue of a class. This function can check whether the encoded value should be decoded to this subclass and return a boolean.

@MappableClass()
abstract class A with AMappable {
  A();
}
  
@MappableClass(discriminatorValue: B.checkType)
class B extends A with BMappable {
  B();
    
  /// checks if [value] should be decoded to [B]
  static bool checkType(value) {
    return value is Map && value['isB'] == true;
  }
}
  
@MappableClass(discriminatorValue: C.checkType)
class C extends A with CMappable {
  C();
    
  /// checks if [value] should be decoded to [C]
  static bool checkType(value) {
    return value is Map && value['isWhat'] == 'C';
  }
}

Added support for serializing fields that are not part of the constructor when annotated with @MappableField().
Added EncodingOptions to toValue method.
Added support for third-party models by using annotated typedefs.
Added renameMethods to build options.
Improved performance of generated encoding and decoding methods.

For a detailed migration guide, see this issue.

2.0.2 #

Fixed an analysis error when using core interfaces.

2.0.1 #

Fixed generated container for private libraries.

2.0.0 #

Mappers are now generated for each file containing annotated classes. This removes the need to specify entry points in the build.yaml.

This is now similar to how packages like json_serializable or freezed generate code.
- Generated files are now part files and need to be included as such.
- All annotated classes must now use their respective <MyClass>Mappable mixin.
- Instead of one global Mapper each class has its own <ClassName>Mapper.
  - A new global container that includes all models can now be generated using @MappableLib(createCombinedContainer: true).
- Mappers can be linked together to enable working with multiple classes.
- Removed @CustomMapper annotation in favor of includeCustomMappers property on @MappableClass().
For a detailed migration guide, see this issue.
Documentation is now separated from the README using the official pub.dev documentation topics. Find the new documentation here
Improvements in performance and support for generics and inheritance.
Added the [CheckTypesHook] to allow for custom discriminator checks on subclasses in a polymorphic class structure.

CopyWith is now more powerful and also works for generic or polymorphic classes, while being completely type-safe.

When called on a superclass, the concrete subtype will be retained through a .copyWith call, which also respects generics:

  // with `class A` and `class B<T> extends A`
  A a = B<int>(); // static type A, dynamic type B<int>
  
  // signature will be `A copyWith()`, so static type A
  A a2 = a.copyWith(); 
  
  // this will still resolve to a dynamic type of B<int>
  assert(a2 is B<int>);
