quds_office_engine 0.5.2

Pure Dart Office + PDF engine: DOCX, XLSX, PPTX, formulas, BiDi/RTL, PdfFile, pdf_widgets, 100+ report templates, and PDF 1.7 — no Flutter.

Changelog

All notable changes to quds_office_engine are documented here.

0.5.2

• Do not mid-cut Arabic chart axis labels (keeps joining forms intact).

0.5.1

• Soft-wrapped Text keeps the full max width so RTL start / justify paint on the start edge (headers, bullets, paragraphs).
• TextAlign.justify origins follow direction instead of always left.
• Bullet uses TextAlign.start. Chart titles follow direction; long axis labels are shortened to fit their slot.

0.5.0

Report templates that look different, not only read different.

• pdf_templates.dart ships 100+ classified report templates across commerce, finance, people, operations, narrative, data, education, property, logistics, and programs. Pick a named class (InvoiceTemplate, PurchaseOrderTemplate, …) and keep developing it.
• SheetSkin is the composition surface: invoice bar, receipt slip, letterhead, certificate frame, payslip split, checklist boxes, route endpoints, voucher, grades, identity panel, notice strip, journal, comparison columns, and more. Labels stay language. Direction stays layout. TemplateTheme.copyWith stays brand.
• TemplateCatalog.all / inCategory index every entry. TemplateSuite.demo writes a sample page. joinTemplateFiles joins English and Arabic into one PDF.
• Table.fromTextArray defaults to AlignmentDirectional.topStart, so Arabic table cells pin text to the start edge in RTL.
• pdf_widgets Flutter twins: Transform, clips, FractionallySizedBox, IntrinsicHeight, CustomPaint, ListTile, directional insets, and more. TextOverflow.ellipsis cuts a line.
• OfficeColors.red and other common names are RRGGBB strings for OfficePalette without touching Flutter Colors.

0.4.0

PDF is a file you can assemble, not only a file you can open or export.

• PdfToolbox grafts a new PDF 1.7 so fonts and images survive merge, extract, split, reorder, remove, reverse, insert, and mix. Range groups are 1-based (1-3, 8-10, 15). One source may contribute several groups.
• /Rotate is a clockwise quarter-turn added to the existing value. It does not rewrite MediaBox. PdfPageView maps view space to unrotated crop space.
• Appearance overlays: Helvetica stamp, page numbers, Bates, and CropBox crop. Stamp is Latin only. A shaped watermark belongs on pdf_widgets.
• pdf_widgets watermark is one rotated string (ActualText + visual-order glyphs) so Arabic stays joined.
• Office slide export can stack two slides on one page (slidesPerPage: 2). The default remains one slide per page.
• ArabicShaper.nominal maps presentation forms back to isolated letters.
• Package documentation covers the full public surface, including honest limits (no OCR, no CMS verify, no certified PDF/A, no content-stream reflow).

0.3.1

• Keep pdf_widgets on its own library import (package:quds_office_engine/pdf_widgets.dart) so Flutter hosts do not see colliding Text / TextStyle / Widget names from the main barrel.

0.3.0

Office + PDF in one pure-Dart engine. This release makes PDF a first-class citizen alongside DOCX / XLSX / PPTX — open, compose, and export without Flutter.

PDF as a file (PdfFile)

• Open ISO 32000 packages: xref table/stream, object streams, incremental updates, filters (including CCITT G3/G4), encryption/password paths.
• Display list for page paint (b/b*, graphics state, Type 3, axial/radial shadings, OCG, SMask→RGBA, CMYK/ICCBased images).
• Text extract (WinAnsi / MacRoman / PDFDoc, Standard-14, /ActualText, /StructTreeRoot reading order).
• Typed honesty for signatures (ByteRange status), PDF/A detection (not certification), and unsupported codecs (JBIG2/JPX, in-engine CFF raster).

PDF widgets (pdf_widgets.dart)

• Flutter-like constraint layout in pure Dart: Document, Page / MultiPage, Table / TableBorder / column widths, flex, text, media.
• Real bold faces via Document.fontBold (Type0 /F3), not faux stroke.
• Table cells expand to full width×row height (package:pdf-style fills).
• Synchronous Document.save() → native PdfDocument writer bytes.

Office (unchanged strengths)

• Round-trip DOCX / XLSX / PPTX, formulas, BiDi/RTL, isolate open/save.
• OfficePdfExport still compiles Word / Excel / PowerPoint to PDF 1.7.

Breaking

• Word widget DSL removed. Use pdf_widgets for PDF layout and DocxDocumentBuilder for DOCX.

0.2.0

• English package documentation, Word widget DSL (later removed), and PDF export polish.

0.1.0

• First public release: Office builders, models, formulas, BiDi, PDF export.
