这是我的 Html 文本
<p>hello</p>
<div class="mathjax-equation">
\(x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\)
</div>
我想在没有 Webview 包的情况下在 flutter 移动屏幕上显示这个数学视图。我该怎么办?
检查这个包flutter_tex
class MathJaxExample extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('MathJax Example'),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Text('Hello'),
Mathjax(
mathjaxText: r'$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$',
textStyle: TextStyle(fontSize: 24.0),
),
],
),
),
),
);
}
}
但我也建议你阅读该文档。
您可以使用 math_tex_package 来显示数学方程,因为您将重新格式化编写公式的方式
