Dart Flutter : How to use multiple statements in ternary inside a flutter widget [closed]

Question

Is it possible to write such a line, and within this line I want change a variable value?

opacity: condition == true ? 1, stringName ='Steve' : 0

Answer 1

Not sure what you expect the code to do exactly but my guess

opacity: condition == true ? (){ stringName = 'Steve'; return 0; }() : 0;

You can't have a list of expressions in the true or false part, only one single expression.

Answer 2

I think this is what you wanted

opacity : condition== true ? 1 : stringName == "Steve" ? 0 : 2,
