tamil_pdf_fixer #

Unicode-first Tamil text rendering for PDFs generated with Flutter's pdf package.

This package is a thin language-focused facade over pdf_text_shaper. HarfBuzz performs real OpenType shaping while this package adds convenient font loading, script detection and PDF widgets.

Features #

• HarfBuzz GSUB/GPOS shaping through pdf_text_shaper
• Unicode-first Tamil text
• fallback fonts for mixed-script documents
• multiline wrapping and reusable typography
• optional invisible Unicode layer for search/copy
• TamilText, TamilParagraph, TamilHeader
• TamilRichText, TamilBulletList, TamilTable
• TamilFontManager with safe asset caching/retry
• no bundled fonts

Install #

dependencies:
  tamil_pdf_fixer: ^1.0.0

Add a Unicode OpenType font that supports the Tamil script. For example, a suitable Noto font such as NotoSansTamil-Regular.ttf.

Basic usage #

final font = await TamilFontManager.instance.loadAsset(
  'assets/fonts/NotoSansTamil-Regular.ttf',
);

TamilParagraph(
  'தமிழ்: நான் தமிழில் எழுதுகிறேன்.',
  font: font,
  fontSize: 14,
)

Typography #

final typography = TamilTypography(
  regularFont: regular,
  boldFont: bold,
  fallbackFonts: [latinRegular],
  boldFallbackFonts: [latinBold],
);

TamilHeader(
  'Tamil document',
  style: typography.heading(fontSize: 24),
)

Detection #

'தமிழ்: நான் தமிழில் எழுதுகிறேன்.'.containsTamil; // true

Font lifecycle #

await TamilFontManager.instance.dispose();
