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.
