This package includes several "constable math functions" that can be called at compile-time which dart:math mostly cannot, returning const double, and can be used as compile-time constants.
They are const constructors of extension type on double implements double, therefore can be used just like normal double, with almost 0 cost.
Note
This package is not and will not be optimized for runtime, if runtime optimization is needed for calculations, then consider using 'dart:math' or other libraries.

In pubspec.yaml, add
dependencies:
const_math: ^1.0.2and run pub get. Import the package with
import 'package:const_math/const_math.dart';ConstMath has compile-time math functions that dart:math does not provide, implemented by extension type on double.
const mySinValue = ConstMath.sin(3);If ConstMath feels too verbose, then you can do something like this:
typedef CM = ConstMath;
const seventhRoot2 = CM.rt7(2);These values can also be passed as argument to other const constructors, or inside another ConstMath function.
const sinOfSin1 = CM.sin(CM.sin(1));If you need support or to report bugs, email: const_math_support@worldoverwrite.com
