Element runtime APIs

Each element package's main library adds Dart extension methods to DocumentCommandTarget, so they appear on DocumentEditorController once you import the package. The command runs only if the matching extension is installed.

import 'package:vyuh_document_extension_table/vyuh_document_extension_table.dart';

controller.insertTable(rows: 3, cols: 2);

Package libraries

Element packages split their format adapters into libraries so an app pulls in only what it uses:

Library	Contents
element.dart	The typed element and its commands (Elements)
<package>.dart	Canonical blocks, definitions, command keys, controller methods
docx.dart, pdf.dart, html.dart, markdown.dart	Format contributions, for example DividerDocxCodecContribution, CodeBlockDocxCodecContribution, createMermaidMarkdownExtension()
layout.dart	Layout adapters
integration.dart	Contracts for sibling packages

Editor packages

Package	Main exports
	KatexDocumentExtension, createKatexMarkdownExtension(); math.dart for standalone math painting
	MermaidDocumentExtension; mermaid.dart for standalone Mermaid painting
