i am trying to evaluate a string like "pow(x, 2) * y" in Flutter.
Example Code:
Double x = 2.34;
Double y = 2.10;
String formular = "pow(x, 2) * y";
Now i would like to evaluate the string to get the result of:
pow(2.34, 2) * 2.10;
Is there a way to do this?
I tried to work with https://pub.dartlang.org/packages/expressions, but couldn't figure out how to solve my problem.
I am thankful for any help.

The example in the readme of theexpressionspackage looks quite similar to what you have. What problem did you run into when you tried? Please add the code to your question that demonstrates what you tried and the error messages you got.
