Flutter Khmer Pdf -

Generating PDFs with Khmer text in Flutter requires specific handling because standard PDF fonts do not support Khmer Unicode characters. To display Khmer correctly, you must embed a TrueType font (.ttf) that supports Khmer Unicode, such as Khmer OS or Battambang. Step-by-Step Implementation 1. Add Dependencies Add the following to your pubspec.yaml file:

pdf.addPage(pw.Page( build: (pw.Context context) return pw.Center( child: pw.Text('សូមស្វាគមន៍', font: khmerFont, fontSize: 40), ); , ));

final output = File('example.pdf');
await pdfDocument.save(output);

Step 1: Add Dependencies

First, you need to add a dependency to your pubspec.yaml file to use a package that can help generate PDFs. A popular package for this purpose is pdf. flutter khmer pdf

• The Khmer Issue: By default, this library often struggles with Khmer text shaping. If you simply load a Khmer font and print text, the complex stacking of characters may not render correctly.
• The Solution: The modern versions of this package have improved CTL support. The key is using a properly formatted TrueType Font (TTF) file that supports Khmer Unicode (e.g., Khmer OS Siemreap or Battambang). Developers must ensure the font is loaded asynchronously and passed correctly to the TextStyle.
