kleak.devThe most complete unit converter for Dart/Flutter which also do localizations.
Easily convert unit from and to the international system of units and automatically get the localization for it.
How it work #
Conversions #
This package use extension on num to allow you to convert easily from one unit to another.
For example if you want to transform celsius to fahrenheit here is the code:
0.toKelvin(TemperatureUnit.celsius).toFahrenheit;
Localization #
We take care of the localization of the unit for you as an example on length this code will be localized:
isLocalizations.length.locale(12, UnitSystem.international); // 0.012 km
This is due to the fact that international system base unit for length is the meters.
