Warns when a loop condition is not modified within the loop.

Example

❌ Bad:

void fn(String left, String right) {
  // LINT: None of the local variables in this condition are modified within the loop.
  //  Try checking for a potential mistake.
  while (left.isNotEmpty) {
    print(left);
  }
  left = '';

  // LINT: None of the local variables in this condition are modified within the loop.
  //  Try checking for a potential mistake.
  while (left != right) {
    print(left);
  }
}

✅ Good:

void fn(String left, String right) {
  while (left.isNotEmpty) {
    print(left);
    left = '';
  }

  // LINT: None of the local variables in this condition are modified within the loop.
  //  Try checking for a potential mistake.
  while (left != right) {
    print(left);
  }
}
