2.11 preserves JSON format 1. The Dart connector field is now route, while the serialized field remains router; existing saved drawings require no key migration.

dart pub add vyuh_diagram_codec_json --hosted-url https://pub.vyuh.tech

Register your registry token first with dart pub token add https://pub.vyuh.tech; see package access.

Usage

With a controller, pass the format; the installed extensions' codecs are used automatically:

final json = controller.save(DiagramJsonCodec.new);
controller.edits.load(json, format: DiagramJsonCodec.new);

final reopened = DiagramController.open(
  json,
  format: DiagramJsonCodec.new,
  configuration: DiagramConfiguration(extensions: [EditorExtension()]),
);

On its own:

import 'package:vyuh_diagram_codec_json/vyuh_diagram_codec_json.dart';
import 'package:vyuh_diagram_types/vyuh_diagram_types.dart';

const codec = DiagramJsonCodec(DiagramModelCodecs.empty());
final json = codec.encode(document);
final restored = codec.decode(json);
