i have tried the latex example in my app, but the output seems only renders markdown correctly but the latex equation showing as plain text , is this latex feature support in this module? or am i doing anything wrong?
below is my code example
import React from "react";
import Markdown, { Renderer, MarkedTokenizer, MarkedLexer } from "react-native-marked";
class CustomTokenizer extends MarkedTokenizer {
// Override
codespan(src) {
const match = src.match(/^\$+([^\$\n]+?)\$+/);
if (match?.[1]) {
const text = match[1].trim();
const token = {
type: 'custom',
raw: match[0], // should be the exact regex pattern match
identifier: "latex", // Unique identifier for the token
tokens: MarkedLexer(text), // optional, can be used if the markdown contains children
args: { // optional, can be used to send more information to the renderer
text: text,
}
};
return token;
}
return super.codespan(src);
}
}
class CustomRenderer extends Renderer {
// Custom Token implementation
custom(identifier, _raw, _children, args) {
const text = args?.text;
if (identifier === "latex") {
const styles = {
padding: 16,
minWidth: "100%",
backgroundColor: "#f6f8fa"
};
return this.code(text.trim(), "latex", styles);
}
return null;
}
}
const renderer = new CustomRenderer();
const tokenizer = new CustomTokenizer();
const markdown = `
# 🧠 Markdown with LaTeX
This example showcases **Markdown** combined with _LaTeX_ rendering.
## 📌 Features
- Headings (like this one)
- **Bold**, *Italic*, ~~Strikethrough~~
- [Link](https://reactnative.dev)
- Images: 
- Blockquotes:
> Markdown is awesome!
- Lists:
- Inline math: $a^2 + b^2 = c^2$
- Block math:
$$
\\int_0^\\infty e^{-x^2} dx = \\frac{\\sqrt{\\pi}}{2}
$$
- Code:
\`\`\`js
const greet = () => console.log("Hello");
\`\`\`
## 🎯 Inline & Block Math
Text before inline: $E = mc^2$ and after.
And now a block:
$$
\\nabla \\cdot \\vec{E} = \\frac{\\rho}{\\varepsilon_0}
$$

> Math + Markdown = ❤️
