BitMarkdown

BitMarkdown is a minimal, fast, and Flutter-friendly Markdown renderer that allows you to render Markdown content directly in Flutter widgets without converting it to HTML. It is lightweight and optimized for performance, making it suitable for large documents and mobile apps.

Features

• Blazing Fast - Uses ListView.builder for optimal performance with large documents (1k-100k+ lines)
• Minimal - Clean, simple codebase with no dependencies
• Extensible - Modular architecture makes adding new features seamless
• Lightweight - Only ~300 lines of code

Supported Markdown

• Headings (# to ######)
• Bold (**text**) and Italic (*text*)
• Unordered lists (- item)
• Ordered lists (1. item)
• Tables (| cell | cell |)
• and more...

Installation

Add this to your pubspec.yaml:

dependencies:
  bitmarkdown: ^0.0.3

Usage

import 'package:flutter/material.dart';
import 'package:bit_markdown/bit_markdown.dart';

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: BitMarkdown('''
# Hello World

This is **bold** and *italic* text.

- Item 1
- Item 2

| Col A | Col B |
| 1 | 2 |
        '''),
      ),
    );
  }
}

Custom Styling

BitMarkdown(
  data,
  style: TextStyle(
    fontSize: 18,
    color: Colors.grey.shade800,
  ),
)

Performance

BitMarkdown uses lazy loading with ListView.builder, so it can handle massive documents efficiently:

• 1,000 lines: Instant
• 10,000 lines: Smooth
• 100,000 lines: Still works

Architecture

lib/
├── bit_markdown.dart         # Main export
└── src/
    ├── bitmarkdown_widget.dart  # Main widget
    ├── parser.dart              # Parsing logic
    └── renderer.dart            # Rendering logic

Separation of concerns:

• parser.dart - Converts markdown strings to element objects
• renderer.dart - Converts elements to Flutter widgets
• bitmarkdown_widget.dart - Orchestrates everything
