Math Formulae Manager

A comprehensive command-line application for managing and computing mathematical formulas across various disciplines including mathematics, physics, medicine, and engineering.

This project uses dart language, and flutter framework. It leverages d4rt library to execute formulas.

Getting Started

This project uses flutter, so a valid installation is needed in order to build it.

For convenience, a containerized build is provided. It is based on podman and podman-compose. See Makefile for details.
