Features #

Installation #

Add to your pubspec.yaml:

dependencies:
  bangla_pdf: ^1.0.2

Install packages:

flutter pub get

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(
  'বাংলা সাধারণ টেক্সট',
  fontType: BanglaFontType.kalpurush,
  fontSize: 20,
),
pw.SizedBox(height: 10),
pw.Text(
  'বেঁচে থাকার মত আনন্দ আর কিছুই নেই।'.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/bangla_pdf.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(
            'বাংলা সাধারণ টেক্সট',
            fontType: BanglaFontType.kalpurush,
            fontSize: 20,
          ),
          pw.SizedBox(height: 10),
          pw.Text(
            'বেঁচে থাকার মত আনন্দ আর কিছুই নেই।'.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);
}

Step 3: Use PDF Fixer Widgets #

Bangla PDF provides ready-to-use widgets that automatically handle font corrections:

• BanglaAutoText – Automatic Bangla and English mixing
• BanglaText – Basic Bangla text
• BanglaRichText – Multi-style text spans
• BanglaHeader – Bold headers
• BanglaParagraph – Properly formatted paragraphs
• BanglaBulletList – Bullet lists
• BanglaTable – Tables with headers and formatted cells

These widgets integrate seamlessly with the pdf package, allowing you to focus on content while the package handles Bangla text corrections.

1. BanglaAutoText #

Automatically detects and renders mixed Bangla and English text with appropriate fonts:

BanglaAutoText(
  'আমার নাম Zaman Sheikh এবং আমি ঢাকা থেকে এসেছি।',
  fontSize: 16,
  banglaFontType: BanglaFontType.kalpurush,
  color: PdfColors.black,
);

With custom styling:

BanglaAutoText(
  'দাম: ৳ 500 Price: $50',
  fontSize: 14,
  banglaFontType: BanglaFontType.july,
  fontWeight: pw.FontWeight.bold,
  color: PdfColors.blue,
);

BanglaRichText(
  spans: [
    BanglaTextSpan('বাংলা বোল্ড ', fontWeight: pw.FontWeight.bold),
    BanglaTextSpan('এবং ইটালিক', fontType: BanglaFontType.julyItalic),
  ],
);

4. BanglaHeader #

    ['নাম (Name)', 'বয়স (Age)', 'শহর (City)'],
    ['আহমেদ Ahmed', '२५ (25)', 'ঢাকা Dhaka'],
    ['সারা Sara', '३० (30)', 'চট্টগ্রাম Chittagong'],
    ['রাহুল Rahul', '०२८ (28)', 'সিলেট Sylhet'],
  ],
  fontType: BanglaFontType.tomalicca,
  fontSize: 14,
  fontWeight: pw.FontWeight.normal,
);

Step 4: TextStyle & Widget Shortcuts #
