how to set condition in String Flutter

Question

I am looping Text Field hundreds times

for (var i = 0; i < 100; i++)

my label Text is look like this labelText: '${i + 1}',

I want to set Condition if i is below 10 then add extra 0 before number

I did try with like this

'${i < 10 ? "0"i + 1 : i + 1}',

getting error Expected to Find '}'

for (var i = 0; i < 100; i++) print(i.toString().padLeft(2, '0')); or in your case: labelText: i.toString().padLeft(2, '0') — pskink

@JahidulIslam yes, need to increase by 1: labelText: (i + 1).toString().padLeft(2, '0') — pskink

Here is a another solution by using String's padLeft method.

  for (var i = 0 ; i < 100 ; i++) {
    print(i.toString().padLeft(2, '0'));
  }

for (var i = 0; i < 100; i++){
    print('${i+1 < 10 ? "0${i + 1}" : i + 1}');
  }
