Use $ as delimiters in Katex

[backviet]

I'm a newbie with katex, so I don't know how to use katex with exists my data. Now I display math data with mathjax in website with config:

<script type="text/x-mathjax-config">
  MathJax.Hub.Config({tex2jax: {inlineMath: [['$','$'], ['\\(','\\)']]}});
</script>

How to I setup katex with similar config to display my exist data by flutter_math_fork.

Below is my test codes:

import 'package:flutter/material.dart';
import 'package:flutter_math_fork/flutter_math.dart';

class Demome extends StatelessWidget {
  const Demome({
    Key? key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    final expression =
        "\\({{\\left( x-2 \\right)}^{2}}+{{\\left( y-1 \\right)}^{2}}+{{\\left( z+3 \\right)}^{2}}=13.\\)";
    return Column(
      crossAxisAlignment: CrossAxisAlignment.center,
      mainAxisSize: MainAxisSize.min,
      mainAxisAlignment: MainAxisAlignment.start,
      children: <Widget>[
        Padding(
          padding: const EdgeInsets.all(8.0),
          child: Text(expression, softWrap: true),
        ),
        Divider(
          thickness: 1.0,
          height: 1.0,
        ),
        Expanded(
          child: Center(
            child: Math.tex(
              expression,
              mathStyle: MathStyle.textCramped,
              settings: TexParserSettings(
                strict: Strict.ignore,
                displayMode: true,
              ),
            ),
          ),
        )
      ],
    );
  }
}

And I have received an error message: "Parse error: Can't use '\(' in math mode".

I have tried to read documents, test codes and sample codes many times but I can't find any solution for my situation.

Hi, Actually when you require $\TeX$ code to be rendered on the web in math mode, you enclose them as $...$ or $$...$$.

The MathJax pre-processor you've mentioned above actually changes the above delimiters to the custom one you need, here $...$ is replaced by \(...\)

In case of this plugin, the code you pass is rendered in math mode and thus, you don't need the delimiters \(...\)

Hello, can this plugin allow text and mathematical formulas to be displayed in one line? Below is test codes:

import 'package:flutter/material.dart';
import 'package:flutter_math_fork/flutter_math.dart';

class Demome extends StatelessWidget {
  const Demome({
    Key? key,
  }) : super(key: key);

  @override
  Widget build(BuildContext context) {
    final expression =
        "Calculus is a branch of mathematics that deals with the derivatives and integrals of functions. Here is an example calculus:
Example: Find the derivative of the function $f(x)=x^3$at $x=2$.
Solution: Using the derivation formula, we can find the derivation of $f'(x)$:
$$f'(x) = 3x^2$$
Then, put $x=2$into $f'(x)$to get:
$$f'(2) = 3(2)^2 = 12$$
Thus, the derivative of the function $f(x)$at $x=2$is $12$.";
    return Column(
      crossAxisAlignment: CrossAxisAlignment.center,
      mainAxisSize: MainAxisSize.min,
      mainAxisAlignment: MainAxisAlignment.start,
      children: <Widget>[
        Padding(
          padding: const EdgeInsets.all(8.0),
          child: Text(expression, softWrap: true),
        ),
        Divider(
          thickness: 1.0,
          height: 1.0,
        ),
        Expanded(
          child: Center(
            child: Math.tex(
              expression,
              mathStyle: MathStyle.textCramped,
              settings: TexParserSettings(
                strict: Strict.ignore,
                displayMode: true,
              ),
            ),
          ),
        )
      ],
    );
  }
}
