how to select last json data-CodePudding

In here i want to make a condition if the dropdown box select the last option it will show new box but i don't know how to make that condition. What i use now is the condition where the option is "Other Impression" selected but the api has 2 language so i cannot hard code the condition. Maybe i think it's like dropdownOption.lastIndexOf .... i don't know

This is the Json

List dummyDropdownOption = [
{
  "value": 1,
  "label": "Sistem Kemudi otomatis dapat diandalkan",
},
{
  "value": 2,
  "label": "Mobilitas tanpa awak mematuhi rambu dan aturan lalu lintas",
},
{
  "value": 3,
  "label": "Mobilitas tanpa awak memiliki kondisi kebersihan yang baik.",
},
{
  "value": 4,
  "label": "Other impressions",
    }, 
];

The condition i use for now

(dropdownValue1 == 'Other impressions')
                  ?

CodePudding user response：

In Dart, you also have a last property on the List. Doc

void main() {
  print(dummyDropdownOption.last);
}

Console log

{value: 4, label: Other impressions}

You can get last index item like below.

dummyDropdownOption[dummyDropdownOption.length - 1]
