Render scientific LaTeX equations using the KaTeX library.
- Mathematics / Maths Equations (Algebra, Calculus, Geometry, Geometry etc...)
- Physics Equations
- Signal Processing Equations
- Chemistry Equations
- Statistics / Stats Equations
- Inherit text style from parent widgets
Note: The bad pub.dev score is due to a known error in the analysis server and not our fault.
katex_flutter is working on Android, iOS, the Web and the Desktop platform.
Note: we recently did significant API changes. Please update any prior code.
KaTeX( @required laTeXCode, // A Text() containing the LaTeX code to be rendered delimiter = r'$', // The delimiter to be used for inline LaTeX displayDelimiter = r'$$', // The delimiter to be used for Display (centered, "important") LaTeX );
What's the difference to CaTeX library?
Another difference is Text support: CaTeX is simply taking any input for Math rendering. We split up into Text and Math parts. You can use a separator (eg. the common "$" or "$$"). Content between these separators is rendered as math while anything outside of these separators is rendered as normal Flutter Text. This makes Text containing only some single formula parts much easier.
Use this package as a library
Add this to your package's pubspec.yaml file:
dependencies: katex_flutter: ^4.0.0+24
You can install packages from the command line with Flutter:
flutter pub get
Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.
Now in your Dart code, you can use:
import 'package:katex_flutter/katex_flutter.dart'; ... // A static LaTeX block which may not change on `setState()` return KaTeX(laTeXCode: Text("\\alpha", style: Theme.of(context) .textTheme .bodyText1 .copyWith(color: Colors.red))) // A dynamic LaTeX block which is rebuilt on `setState()` (less efficient but required sometimes) return Builder(builder: (context) => KaTeX(laTeXCode: Text("\\alpha", style: Theme.of(context) .textTheme .bodyText1 .copyWith(color: Colors.red))))
Please read this document for information on our deprecated library.
This package was initially created for the education project TestApp.
