The flutter_tex package is your gateway to rendering complex mathematical equations and expressions using LaTeX, TeX, and MathML in your Flutter applications. With its full offline capabilities and support for various types of equations, flutter_tex is a versatile tool for developers looking to create mathematically-rich applications.

About flutter_tex

This Flutter package is built to render an array of equations and expressions found in mathematics, physics, chemistry, statistics, and more. It uses powerful JavaScript libraries, namely MathJax and Katex, to deliver its impressive rendering capabilities through a Flutter web view.

How it Works

Imagine you are a skilled chef in a kitchen filled with various ingredients (like MathJax and Katex). You can combine them in unique ways to create delicious equations (equivalent dishes) that your patrons (users) will love. Just as a chef doesn’t need to leave the kitchen to get ingredients, flutter_tex can operate completely offline while serving your app’s mathematical needs.

How to Use flutter_tex

• Step 1: Add the flutter_tex package to your dependencies in the pubspec.yaml file:

dependencies:
  flutter_tex: ^4.0.9

• Step 2: Install packages from the command line:

$ flutter packages get

• Step 3: Implement the necessary configurations for Android, iOS, and Web platforms:
• Android: Add the following line in AndroidManifest.xml:

android:usesCleartextTraffic=true

• Include required permissions:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>

• iOS: Add the following lines to Info.plist:

<key>NSAppTransportSecurity</key>
<dict>
  <key>NSAllowsArbitraryLoads</key><true/>
  <key>io.flutter.embedded_views_preview</key><true/>
</dict>

• Web: Include scripts in your index.html head tag:

<script src="assets/packages/flutter_tex/js/flutter_tex.js"></script>
<script type="text/javascript">
    window.flutterWebRenderer = 'canvaskit';
</script>

• Step 4: Import the package in your Dart file:

import 'package:flutter_tex/flutter_tex.dart';

• Step 5: Use the TeXView widget within your app:

TeXView(
    child: TeXViewColumn(
        children: [
            TeXViewDocument(r'$$x = -b \pm \sqrt{b^2-4ac} \over 2a.$$'),
        ],
    ),
);

Examples

To get you started, there are several example implementations available:

• TeXView Document Example
• TeXView Markdown Example
• TeXView Quiz Example
• TeXView Custom Fonts Example
• TeXView Image and Video Example

Application and Demo

Check out the application demo on Google Play and the Web Demo.

Troubleshooting

Here are some troubleshooting tips to keep in mind:

• If your equations are not rendering properly, ensure that your permissions and configurations are correctly set up.
• If you’re experiencing performance issues, avoid using too many instances of TeXView in a single page as they can slow down your application.
