Dart and Flutter for loop multiple iterators

I have a for loop in my Flutter project similar to this (simplified):

for(int i=0; i<aVariableDeclaredBefore; i++) Padding(....

Here I need another operation after i++ run as this one anotherVariable–. I can’t do it in {} braces because loop used for Widget manipulation. There is no curly braces there.

I need something like this ((i++)&&(anotherVariable--)) but how ? if it is possible

>Solution :

Use the comma operator:

void main() {
  for (var i = 0, j = 10; i < 10; i++, j++) {
    print('i=$i, j=$j');
  }
}

Output:

i=0, j=10
i=1, j=11
i=2, j=12
i=3, j=13
i=4, j=14
i=5, j=15
i=6, j=16
i=7, j=17
i=8, j=18
i=9, j=19
