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: "^0.4.0"
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.
Now in your Dart code, you can use:
