# flutter_markdown_latex 0.3.4 flutter_markdown_latex: ^0.3.4 copied to clipboard

A extension to render LaTeX in markdown for package flutter_markdown.

# Flutter Markdown Latex #

This extension is created to enhance the functionality of the flutter_markdown package by adding support for rendering LaTeX in markdown. The rendering of LaTeX is achieved through the utilization of the flutter_math_fork package.

## Rendering Samples #

This is inline latex: $f(x) = \sum_{i=0}^{n} \frac{a_i}{1+x}$

This is block level latex:

$$c = \pm\sqrt{a^2 + b^2}$$

This is inline latex with displayMode: $$f(x) = \sum_{i=0}^{n} \frac{a_i}{1+x}$$

The relationship between the height and the side length of an equilateral triangle is:

$\text{Height} = \frac{\sqrt{3}}{2} \times \text{Side Length}$

$\text{X} = \frac{1}{2} \times \text{Y} \times \text{Z} = \frac{1}{2} \times 9 \times \frac{\sqrt{3}}{2} \times 9 = \frac{81\sqrt{3}}{4}$

The basic form of the Taylor series is:

$f(x) = f(a) + f'(a)(x-a) + \frac{f''(a)}{2!}(x-a)^2 + \frac{f'''(a)}{3!}(x-a)^3 + \cdots$

where $$f(x)$$ is the function to be expanded, $$a$$ is the expansion point, $$f'(a)$$, $$f''(a)$$, $$f'''(a)$$, etc., are the first, second, third, and so on derivatives of the function at point $$a$$, and $$n!$$ denotes the factorial of $$n$$.

In particular, when $$a=0$$, this expansion is called the Maclaurin series.


## Getting Started #

Add flutter_markdown_latex to your pubspec.yaml dependencies.

### Import it #

import 'package:flutter_markdown_latex/flutter_markdown_latex.dart';


### Render it #

// with default text style
MarkdownBody(
selectable: true,
data: 'latex: \$c = \\pm\\sqrt{a^2 + b^2}\$',
builders: {
'latex': LatexElementBuilder(),
},
extensionSet: md.ExtensionSet(
[LatexBlockSyntax()],
[LatexInlineSyntax()],
),
),

// with custom text style
MarkdownBody(
selectable: true,
data: 'latex: \$c = \\pm\\sqrt{a^2 + b^2}\$',
builders: {
'latex': LatexElementBuilder(
textStyle: const TextStyle(color: Colors.blue),
textScaleFactor: 1.2,
),
},
extensionSet: md.ExtensionSet(
[LatexBlockSyntax()],
[LatexInlineSyntax()],
),
),
