json_serializable: ^0.2.0 copied to clipboard

BREAKING Types are now segmented into their own libraries.

• package:json_serializable/generators.dart contains Generator implementations.

• package:json_serializable/annotations.dart contains annotations. This library should be imported with your target classes.

• package:json_serializable/type_helpers.dart contains TypeHelper classes and related helpers which allow custom generation for specific types.

BREAKING Generation fails for types that are not a JSON primitive or that do not explicitly supports JSON serialization.

BREAKING TypeHelper:

• Removed can methods. Return null from (de)serialize if the provided type is not supported.

• Added (de)serializeNested arguments to (de)serialize methods allowing generic types. This is how support for Iterable, List, and Map is implemented.

BREAKING JsonKey.jsonName was renamed to name and is now a named parameter.

Added support for optional, non-nullable fields.

Added support for excluding null values when generating JSON.

Eliminated all implicit casts in generated code. These would end up being runtime checks in most cases.

Provide a helpful error when generation fails due to undefined types.

Split off from source_gen.

Add /* unsafe */ comments to generated output likely to be unsafe.

Support (de)serializing values in Map.

Fix ordering of fields when they are initialized via constructor.

Don't use static members when calculating fields to (de)serialize.
