How to map on enumerate?

[Matrix-Zhang]

I have a List

when

 list.iter().enumerate().map((index, color) {
      //todo
    }).toList();

Error: The argument type '((int, ColorSelection), dynamic) Function((int, ColorSelection), dynamic)' can't be assigned to the parameter type 'dynamic Function((int, ColorSelection))'.

Dart still doesn't support destructuring in a closure argument's. You will need to do:

list.iter().enumerate().map((item) {
        final (index, elelemnt) = item;
      //todo
    }).toList();
