A custom-made fully integrated math keyboard in Flutter

by Flutter Awesome

Math Keyboard Developed by Ajay N and Arshad Zanin.

math_keyboard is a package that allows editing math expressions using a typeset input field (so-called “math field”) and a custom-made fully integrated math keyboard in Flutter only – no plugins, no web views.
