SingleVariableFunction class
A callable class built from a string representation of a numerical function.
Two named arguments are required: fromExpression
and withVariable
.
Example
import "package:function_tree/function_tree.dart";
void main() {
final expression = "a^2 + 3*a + 5",
f = SingleVariableFunction(
fromExpression: expression,
withVariable: "a",
),
x = 2.0,
result = f(x);
print("f($x) = $result");
}
Result
f(2.0) = 15.0
