quill_delta_docx

Bidirectional Quill Delta ↔ .docx (Office Open XML) conversion.

• .docx → Delta: paragraphs, runs (bold/italic/underline/strike/ color/size), headings, bullet / ordered / checked lists (via numbering.xml), hyperlinks, embedded images (resolved through word/_rels/document.xml.rels + word/media/)
• Delta → .docx: writes a valid OOXML package — [Content_Types], _rels/.rels, word/document.xml, word/_rels/document.xml.rels, word/styles.xml, word/numbering.xml
• Sync entry points — DocxImporter.importSync / DocxExporter.exportSync
• Out of scope for v0.1: tables, comments, track changes, footnotes, embedded objects, themes, fontTable, multi-section

Quickstart

import 'dart:io';
import 'package:dart_quill_delta/dart_quill_delta.dart';
import 'package:quill_delta_docx/quill_delta_docx.dart';

// .docx -> Delta.
final bytes = await File('input.docx').readAsBytes();
final delta = await DocxImporter().import(bytes);

// Delta -> .docx.
final out = await const DocxExporter().export(delta);
await File('output.docx').writeAsBytes(out);

Options

const opts = DocxOptions(
  pageSize: DocxPageSize.a4,              // .letter, .legal
  imageEmbed: DocxImageEmbed.embedded,    // .dataUri, .externalOrPlaceholder
  defaultFontFamily: 'Calibri',
  defaultFontSizePt: 11,
);
final exporter = DocxExporter(defaultOptions: opts);

How it works

The importer pivots through HTML — every quill_delta_html embed adapter applies automatically (image, video, audio, etc.). The exporter is native; it walks splitIntoLines output directly into OOXML.
