A library to help Dart developers to convert unities and a few other things.


A simple usage example:

import 'package:unities_helper/unities_helper.dart';

main() {
  final temperature = convert<Temperature>(
    Temperature.celcius, // from
    Temperature.fahrenheit, // to
    25, // value
  ); /// Convert 25°C into Fahrenheit

A more detailed example can be found on the example folder
