visualpdf 1.8.5

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

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.
