attributedTextFromMarkdown function

AttributedText attributedTextFromMarkdown(String markdown)

Parses markdown and returns it as AttributedText.

The markdown is expected to represent a single paragraph of content. If the markdown isn't text-based (e.g., an image), or if the markdown includes more than one paragraph of content, an exception is thrown.

Implementation

AttributedText attributedTextFromMarkdown(String markdown) {
  if (markdown.isEmpty) {
    return AttributedText();
  }

  final document = deserializeMarkdownToDocument(markdown);
  assert(document.nodeCount == 1,
      "Tried to parse Markdown to AttributedText. Expected one paragraph node but ended up with ${document.nodeCount} parsed nodes.");
  assert(document.first is ParagraphNode,
      "Tried to parse Markdown to AttributedText. Expected text but found content type: ${document.first.runtimeType}");
  return (document.first as ParagraphNode).text;
}
