ItemsConverter<T> class
abstract
Used for getting objects from and to Map.
This is used for most handlers that
extend ItemsHandler for getting statically typed object. There are only 2 methods
that need to be overridden, fromJson and toJson.
If user is using json_serializable it's pretty straight forward to write converter.
Default converter form ItemsHandler is MapItemsConverter that will simply clone
Map to another Map. You can check how SettingsConverter, ActivityConverter,
or similar classes work.
Map must have String as key, because that's only valid value for JSON.
