A Dart package to programmatically build and manipulate LaTeX math expressions using a tree-based structure.

math_latex_builder

A Dart package to programmatically build and manipulate LaTeX math expressions using a tree-based structure.

Features

• Build complex LaTeX expressions with a simple, intuitive API.
• Navigate and edit expressions using cursor movements.
• Support for common LaTeX elements like fractions, roots, and powers.
• Written in pure Dart, making it compatible with any Dart or Flutter project.

Installation

Add the following to your pubspec.yaml file:

dependencies:
  math_latex_builder: ^1.0.3

Then run dart pub get or flutter pub get.

Usage

import 'package:math_latex_builder/math_latex_builder.dart';

void main() {
  final LaTeXTree tree = LaTeXTree();

  tree.addChildLeaf(LEType.numberLeaf, "4");
  tree.addChildLeaf(LEType.operatorLeaf, "+");
  tree.addChildNode(LEType.fractionNode);
  tree.addChildLeaf(LEType.numberLeaf, "1");
  tree.addChildLeaf(LEType.numberLeaf, "5");
  tree.addChildLeaf(LEType.operatorLeaf, "-");
  tree.addChildNode(LEType.squareRootNode);
  tree.addChildLeaf(LEType.numberLeaf, "7");
  tree.moveDown();
  tree.addChildNode(LEType.nthRootNode);
  tree.addChildLeaf(LEType.numberLeaf, "9");
  tree.moveRight();
  tree.addChildNode(LEType.fractionNode);
  tree.addChildLeaf(LEType.numberLeaf, "3");
  tree.moveDown();
  tree.addChildLeaf(LEType.numberLeaf, "8");

  print("result : ${tree.toLaTeXString}");
  // 4+\frac{15-\sqrt{7}}{\sqrt[9]{\frac{3}{8|}}}
}
