flutter_markdown_latex

Description:

flutter markdown latex

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.
