Flutter: Can I pass arguments to a function defined in an onPress event on a button?

Question

I have a simple form with a button to calculate the form. I figure it\'s better to hit the button to start the action of calculating and pass the variables to the dumb function

Answer 1

e.g.

    int  result = 0;

    void calculate(num1, num2) {
     setState(() {
         result = num1 + num2;
     });
    }


    new RaisedButton(
          onPressed: () => calculate(1, 100),
          ...
    ),
    new Text("$result")
