An interpreter for math expressions. Supports real and complex numbers.
Note: This library is still in an early state, the test coverage is not perfect, the performance is not optimized and some features are still unimplemented.
var result = evaluate("1+sin(π/2)"); print(result); // prints "2"
Add this to your package's pubspec.yaml file:
dependencies: math_evaluator: "^0.3.5"
You can install packages from the command line:
$ pub get
$ flutter packages get
Alternatively, your editor might support
pub get or
flutter packages get.
Check the docs for your editor to learn more.
