Usage

To use HTMLtoPDFWidgets in your Flutter project, follow these simple steps:

1. Import the package:

import 'package:htmltopdfwidgets/htmltopdfwidgets.dart';

2. Convert HTML to PDF:

final htmlContent = '''
  <h1>Heading Example</h1>
  <p>This is a paragraph.</p>
  <img src="image.jpg" alt="Example Image" />
  <blockquote>This is a quote.</blockquote>
  <ul>
    <li>First item</li>
    <li>Second item</li>
    <li>Third item</li>
  </ul>
''';

  var filePath = 'test/example.pdf';
  var file = File(filePath);
  final newpdf = Document();
  List<Widget> widgets = await HTMLToPdf().convert(htmlContent);
  newpdf.addPage(MultiPage(
      maxPages: 200,
      build: (context) {
        return widgets;
      }));
  await file.writeAsBytes(await newpdf.save());

3. Converting Markdown to PDF:

final markDown = '''
  # Basic Markdown Demo
---
The Basic Markdown Demo shows the effect of the four Markdown extension sets
on formatting basic and extended Markdown tags.

## Overview

The Dart [markdown](https://pub.dev/packages/markdown) package parses Markdown
into HTML. The flutter_markdown package builds on this package using the
abstract syntax tree generated by the parser to make a tree of widgets instead
of HTML elements.

The markdown package supports the basic block and inline Markdown syntax
specified in the original Markdown implementation as well as a few Markdown
extensions. The markdown package uses extension sets to make extension
management easy. There are four pre-defined extension sets; none, Common Mark,
GitHub Flavored, and GitHub Web. The default extension set used by the
flutter_markdown package is GitHub Flavored.

The Basic Markdown Demo shows the effect each of the pre-defined extension sets
has on a test Markdown document with basic and extended Markdown tags. Use the
Extension Set dropdown menu to select an extension set and view the Markdown
widget's output.

## Comments

Since GitHub Flavored is the default extension set, it is the initial setting
for the formatted Markdown view in the demo.
''';

  final List<Widget> markdownWidgets = await HTMLToPdf().convertMarkdown(markDown);
final markdownPdf = Document();
markdownPdf.addPage(MultiPage(
  build: (context) => markdownWidgets,
));
await File('markdown_example.pdf').writeAsBytes(await markdownPdf.save());
