flutter_quill_kit_markdown

Bidirectional Quill Delta ↔ Markdown conversion in pure Dart — the Markdown companion to flutter_quill_kit, also usable standalone or server-side. Depends only on dart_quill_delta and markdown; no Flutter.

Installation

dart pub add flutter_quill_kit_markdown

Pure Dart — usable in Flutter apps, CLI tools, and on the server.

Quick start

import 'package:flutter_quill_kit_markdown/flutter_quill_kit_markdown.dart';

// Markdown -> Delta (always a valid, insert-only, '\n'-terminated document):
final delta = markdownToDelta('# Hello\n\nSome **bold** text.');

// Delta -> Markdown:
final markdown = deltaToMarkdown(delta);

The function forms wrap the configurable MarkdownToDelta and DeltaToMarkdown classes.

Supported syntax

Both directions cover: bold, italic, strikethrough (GFM), inline code, links, images, headers 1–6, ordered and bullet lists (nesting ↔ the Quill indent attribute), GFM task-list checklists (- [x] / - [ ]), blockquotes, and fenced code blocks with language ({"code-block": "dart"}).

Attributes Markdown cannot express (color, background, font, size, align, direction, ...) are dropped on the way out and reported through the onUnsupported hook:

final md = deltaToMarkdown(
  delta,
  onUnsupported: (key, value) => log('dropped $key: $value'),
);

Underline has no Markdown syntax; opt into an HTML fallback to round-trip it as literal <u>...</u>:

deltaToMarkdown(delta, htmlFallback: true);
markdownToDelta(source, htmlFallback: true);

Delta compatibility

Attribute keys and values match what Quill, flutter_quill and flutter_quill_kit write (bold, strike, code-block, list: "ordered", ...), redeclared locally as QuillKeys so this package needs no editor dependency.
