CodePudding user response：

You can use it like this:

for (int index = 0; i<options.length; i  ) {
  var option = options[index];
  Text(option);
}

Edit: Maybe a outer index variable will do.

int index = 0;
for (var i in options) {
  Text(i);
  index  ;
}

options.indexOf(i) will return the index of the element
