Dart – Detects when in a list there is a 'false' with a 'true' in the next index

April 21, 2022

I would like to create a script in Dart that detects when in the OutputBool2 list there is a ‘false’ with a ‘true’ in the next index

I created this script, but it doesn’t seem to work:

List OutputIndex2 = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23];
List OutpuBool2 = [false, false, false, false, false, false, false, true, false, false, false, false, true, false, false, false, false, false, false, false, false, false, false, false];


for (int j in OutputIndex2.sublist(0, OutputList2.length - 1)) {
      print(j);

      if (OutputBool2[j] == false && OutputList2[j + 1] == true) {
        print(FIND!!);

      }
    }

Can anyone explain to me what I’m doing wrong?
Thanks 🙂

>Solution :

I made this code:

List<bool> OutpuBool2 = [
    false,
    false,
    false,
    false,
    false,
    false,
    false,
    true,
    false,
    false,
    false,
    false,
    true,
    false,
    false,
    false,
    false,
    false,
    false,
    false,
    false,
    false,
    false,
    false
  ];
  for (var i = 0; i < OutpuBool2.length; i++) {
    if (OutpuBool2[i] == false) {
      if (OutpuBool2[i + 1] == true) {
        print('There is a false with a true in the next index in index: $i');
      }
    }
  }

and this is the result:
There is a false with a true in the next index in index: 6
There is a false with a true in the next index in index: 11

is that what you meant?
