Usage ✨

Note BanglaFontType: 🎨 The BanglaFontType class is a centralized enum of 22+ Bangla fonts for PDF generation. It simplifies working with Bangla text in Flutter by providing ready-to-use pw.TextStyle and pw.Text widgets, making font assignment seamless and reducing boilerplate.

Step 1: Initialize Fonts

Before using any widgets, initialize the font manager:

await BanglaFontManager().initialize();

This ensures all fonts are loaded and ready for use.

Step 2: Fix Bangla Text in PDFs

Use the .fix extension to automatically correct broken Bangla text:

BanglaText(
  'āĻŦāĻžāĻ‚āĻ˛āĻž āĻ¸āĻžāĻ§āĻžāĻ°āĻŖ āĻŸā§‡āĻ•ā§āĻ¸āĻŸ',
  fontType: BanglaFontType.kalpurush,
  fontSize: 20,
),
pw.SizedBox(height: 10),
pw.Text(
  'āĻŦā§‡āĻāĻšā§‡ āĻĨāĻžāĻ•āĻžāĻ° āĻŽāĻ¤ āĻ†āĻ¨āĻ¨ā§āĻĻ āĻ†āĻ° āĻ•āĻŋāĻ›ā§āĻ‡ āĻ¨ā§‡āĻ‡āĨ¤'.fix,
  style: BanglaFontType.july.ts(
    fontSize: 24,
    fontWeight: pw.FontWeight.bold,
    color: PdfColors.red,
  ),
),

Most widgets apply .fix internally, so manual usage is optional.

Example: Generate a PDF in Flutter

import 'package:bangla_pdf_fixer/bangla_pdf_fixer.dart';
import 'package:pdf/widgets.dart' as pw;
import 'package:path_provider/path_provider.dart';
import 'package:open_file/open_file.dart';
import 'dart:io';

Future<void> generateAndOpenPdf() async {
  await BanglaFontManager().initialize();

  final pdf = pw.Document();

  pdf.addPage(
    pw.Page(
      build: (context) => pw.Column(
        crossAxisAlignment: pw.CrossAxisAlignment.start,
        children: [
          BanglaText(
            'āĻŦāĻžāĻ‚āĻ˛āĻž āĻ¸āĻžāĻ§āĻžāĻ°āĻŖ āĻŸā§‡āĻ•ā§āĻ¸āĻŸ',
            fontType: BanglaFontType.kalpurush,
            fontSize: 20,
          ),
          pw.SizedBox(height: 10),
          pw.Text(
            'āĻŦā§‡āĻāĻšā§‡ āĻĨāĻžāĻ•āĻžāĻ° āĻŽāĻ¤ āĻ†āĻ¨āĻ¨ā§āĻĻ āĻ†āĻ° āĻ•āĻŋāĻ›ā§āĻ‡ āĻ¨ā§‡āĻ‡āĨ¤'.fix,
            style: BanglaFontType.july.ts(
              fontSize: 24,
              fontWeight: pw.FontWeight.bold,
              color: PdfColors.red,
            ),
          ),
        ],
      ),
    ),
  );

  final dir = await getApplicationDocumentsDirectory();
  final file = File("${dir.path}/example.pdf");
  await file.writeAsBytes(await pdf.save());
  await OpenFile.open(file.path);
}

  spans: [
    BanglaTextSpan('āĻŦāĻžāĻ‚āĻ˛āĻž āĻŦā§‹āĻ˛ā§āĻĄ ', fontWeight: pw.FontWeight.bold),
    BanglaTextSpan('āĻāĻŦāĻ‚ āĻ‡āĻŸāĻžāĻ˛āĻŋāĻ•', fontType: BanglaFontType.julyItalic),
  ],
);

  bullet: '>',
);

    ['āĻ¸āĻžāĻ°āĻž', 'ā§Šā§Ļ', 'āĻšāĻŸā§āĻŸāĻ—ā§āĻ°āĻžāĻŽ'],
    ['āĻ°āĻžāĻšā§āĻ˛', 'ā§¨ā§Ž', 'āĻ¸āĻŋāĻ˛ā§‡āĻŸ'],
  ],
  fontType: BanglaFontType.tomalicca,
  fontSize: 16,
  fontWeight: pw.FontWeight.normal,
