final editor = LexicalEditor(nodes: codeNodes);

editor.update(() {
  $getRoot().append(

  );
}, discrete: true);

This package models code; it does not tokenize it. Highlighting is a per-language concern with its own dependency weight, so producing CodeHighlightNodes is left to whatever highlighter your app already uses — the wire format only needs the classification string.

One thing that surprises every port

A code block authored by appending a multi-line text node keeps the newlines inside that text node. Lexical's editing paths avoid \n in text, but its serializer preserves it, so splitting those runs into line breaks would make you unable to open documents Lexical itself produces. A renderer must handle newlines in text content rather than assuming every break is a LineBreakNode.

Wire-compatible with @lexical/code 0.48.x.
