visualpdf 1.8.8

A visual Flutter PDF report designer and runtime for JSON-driven invoices, templates, tables, barcodes, headers, footers, and printing.

1.8.8

• Abstaende folgen wieder der Vorlage. Der Umbruch behandelte auch Hintergrundflaechen als eigene Zeile: Ein grauer Kasten hinter mehreren Feldern schob alles unter sich weg. Zur laufenden Zeile gehoert jetzt, was sich in der Vorlage senkrecht ueberlappt - Felder auf einer Flaeche bleiben darauf liegen.
• Kein fester Zuschlag je Element mehr. Nach jedem Element wurden 12 pt zusaetzlich zum Vorlagenabstand eingefuegt; ueber eine Seite summierte sich das zu sichtbarer Dehnung. Den Abstand gibt jetzt allein die Vorlage vor, Tabellen wachsen und schrumpfen weiterhin mit der Datenmenge.

1.8.7

• Verschachtelte Datenpfade werden aufgeloest. resolvePath verwarf jedes Praefix ausser customer, blowingdata und items: Aus report.weather wurde weather, das gibt es auf oberster Ebene nicht, und der Platzhalter blieb woertlich im Ausdruck stehen. Jetzt zaehlt erst der volle Pfad; nur wenn der nichts findet, wird das erste Glied versuchsweise weggelassen. Alte Vorlagen mit schmueckendem Praefix funktionieren unveraendert weiter.
• Nebeneinanderliegende Felder bleiben in einer Zeile. Der Seitenumbruch stapelte jedes Element einzeln untereinander; drei Felder auf derselben Hoehe ergaben eine Treppe statt einer Zeile. Elemente, die auf nahezu derselben Hoehe beginnen, bilden jetzt eine Zeile, und der Zeiger wandert erst hinter der tiefsten Spalte weiter.

1.8.6

• Unicode-Häkchen durch ASCII ersetzt: Das Zeichen ✓ fehlt in den mitgelieferten Schriften des pdf-Pakets und führte beim Rendern zum Absturz.
• MemoryImage in try-catch gefasst, damit ein einzelnes fehlerhaftes Bild nicht die gesamte PDF-Erzeugung abbricht.
• Bilddekodierung gegen nicht zwischengespeicherte HTTP-URLs abgesichert.

1.8.5

• Ignore section elements that are physically outside of the section container vertical boundaries during pagination.
• Automatically update element sections from overlap when moving elements with keyboard arrow keys.

1.8.4

• Fixed bracket syntax error in designer view structure.

1.8.3

• Added support for moving selected elements with the keyboard arrow keys (1px precision).
• Added support for moving selected elements with Shift + Arrow keys (5px precision).

1.8.2

• Added ElementType.pageBreak which forces a page break in body pagination and stops printing on the remaining page.
• Visualised the pageBreak element in the designer canvas as a orange dashed line saying "Seitenumbruch".

1.8.1

• Fix dynamic text-flow pagination loops: automatically push down and align elements (like lines and labels) below flowing text elements.
• Clean up unused imports and warnings.

1.8.0

• Added custom template upload/saving support via onSave callback parameter in Designer constructor.
• Added direct PDF download / saving feature to VisualPdfRuntime toolbar.
• Made string numeric aggregate parsing robust using RegExp to extract the first decimal group (safely handling trailing abbreviations like "Std.").
• Set isExpanded: true on the table functions dialog dropdown fields to eliminate visual layout overflows.
• Added explicit right/left textAlign properties to SummaryRow text elements to guarantee mathematical alignment under different font weights.

1.7.1

• Fix table subtotal and total summary labels truncation by rendering a full-width row instead of a narrow table cell column.
• Support preloading initialTemplate and initialJson parameters in Designer constructor.

1.7.0

• Added layer ordering, locking, hiding, and a dedicated layer list.
• Added multi-selection with alignment, equal-size, and distribution tools.
• Added visual alignment guides and magnetic snapping to the grid, element edges, centers, and report bands.
• Added named report sections and keep-together settings to VPS elements.
• Added sequential pagination for multiple independently bound tables with repeated headers, automatic page breaks, and final-page summaries.
• Replaced custom polynomial sin/cos approximations with native dart:math functions for better accuracy and lower complexity.
• Added localization (i18n) for default table summary and group footer labels ("Subtotal", "Discount", "Total Amount", "Sum", "VAT") based on report locale.
• Refactored _paginateReport logic to improve code readability and maintainability.
• VPS schema version 6 persists the new layout and section settings.

1.6.1

• Added font-outline validation for embedded TTF and OTF resources.
• CFF/PostScript OTF fonts are no longer passed to the TrueType-only PDF renderer, preventing overlapping glyphs and black squares in PDF output.
• Existing templates safely fall back to Helvetica for incompatible fonts, while new imports explain that a TTF or TrueType-outline OTF is required.

1.6.0

• Added embedded TTF and OTF font resources to VPS templates.
• Added custom-font management and per-element font selection in the editor.
• Embedded fonts are registered for the canvas preview and included in PDF output for Unicode text, international alphabets, and special characters.
• VPS schema version 5 stores font family metadata and Base64 font data while remaining compatible with older templates.

1.5.0

• Added German and English editor and runtime interfaces.
• Added per-report locales with localized date and number formatting.
• Added configurable EUR, USD, CHF, GBP, and JPY currency formatting.
• Locale and currency settings are persisted in VPS templates, with backward- compatible German and EUR defaults.
• Added conditional element printing using data comparisons and empty/present checks.
• Elements can now be restricted to the first or last physical report page.

1.4.0

• Added Web to the officially supported package platforms.
• Removed the unconditional dart:io dependency from the public runtime.
• VPS and JSON browser uploads, browser-compatible saves, PDF preview, and printing remain available through the existing editor and runtime APIs.
• Added Web integration and build documentation.

1.3.0

• Added selectable A5, A4, A3, and A2 paper formats.
• Added portrait and landscape page orientation in the visual editor.
• Canvas dimensions, element bounds, header/footer controls, table pagination, and generated PDFs now follow the selected page layout.
• Paper settings are persisted in VPS schema version 4.
• Older VPS files remain compatible; landscape pages without an explicit orientation are inferred from their stored dimensions.

1.2.0

• Added automatic multi-page pagination for JSON-backed tables.
• Table column headers repeat on continuation pages.
• Template header and footer elements repeat on every physical PDF page.
• PageNumber and PageCount now resolve to the actual generated PDF page.
• Table aggregates, discounts, taxes, and totals are emitted only on the final table page and still use the complete data set.
• Added a ready-to-open VPS template and JSON data file with 100 invoice items.
• Added calculateReportPageCount for previews, validation, and tests.

1.1.0

• Added Android and iOS as supported package platforms.
• Added a responsive phone and tablet editor with slide-out element and property drawers.
• Added a compact mobile runtime toolbar for loading VPS/JSON files and printing.
• The A4 editor canvas now fits both the available width and height and keeps pinch-to-zoom and panning enabled on touch devices.
• Added mobile integration documentation and widget coverage for compact layouts.

1.0.2

• Added full-size screenshots directly to the README so they remain visible on narrow pub.dev layouts where the screenshot sidebar is hidden.

1.0.1

• Removed unsupported relative image embeds from the Pub.dev README.
• Kept the official Pub.dev screenshot gallery and package thumbnail metadata.
