kannada_pdf_fixer

Unicode-first Kannada 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 Kannada text
  • fallback fonts for mixed-script documents
  • multiline wrapping and reusable typography
  • optional invisible Unicode layer for search/copy
  • KannadaText, KannadaParagraph, KannadaHeader
  • KannadaRichText, KannadaBulletList, KannadaTable
  • KannadaFontManager with safe asset caching/retry
  • no bundled fonts

Install

dependencies:
  kannada_pdf_fixer: ^1.0.0

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

Basic usage

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

KannadaParagraph(
  'ಕನ್ನಡ: ನಾನು ಕನ್ನಡದಲ್ಲಿ ಬರೆಯುತ್ತಿದ್ದೇನೆ.',
  font: font,
  fontSize: 14,
)

Typography

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

KannadaHeader(
  'Kannada document',
  style: typography.heading(fontSize: 24),
)

Detection

'ಕನ್ನಡ: ನಾನು ಕನ್ನಡದಲ್ಲಿ ಬರೆಯುತ್ತಿದ್ದೇನೆ.'.containsKannada; // true

Font lifecycle

await KannadaFontManager.instance.dispose();

The package intentionally does not bundle fonts. Verify the license of any font you ship with your application.

Platforms

Android, iOS, Linux, macOS and Windows. Web is not currently supported by the native shaping backend.
