Example Implementation

class ImageDeclaration extends ResourceDeclaration {
  final String path;
  final int width;
  final int height;

  const ImageDeclaration(this.path, this.width, this.height);

  @override
  Map<String, Object> toJson() => {
    'type': 'image',
    'path': path,
    'dimensions': {'width': width, 'height': height}
  };
}
