December 2, 2021

i have 2 dropdowns 1st is toDate and 2nd is fromDate with 1 list of months to be displayed.

List<String> month = [
'January',
'February',
'March',
'April',
'May',

'July',
'August',
'September',
'October',
'November',
'December',
];

in the first dropdown, all the list is shown to select but in the 2nd dropdown, I want to show all values coming after the selected 1st dropdown value.

for example – :
in the first dropdown, I selected ‘March’ the 2nd dropdown the list displayed should be after ‘March’.

How do I do it?

void main() {
  List<String> month = [

    'June',
    'July',

    'October',
    'November',
    'December',
  ];
  var choice = 'March';
  var ind = month.indexOf(choice);
  if (ind > 0) {
    print(month.skip(ind + 1));
  }
}
