preset: recommended

Warns when a for loop increments a wrong variable.

Example​

❌ Bad:

void main() {
  var j = 1;

  for (var i = 0; i < 10; j++) {} // LINT: Incremented variable differs from the declared one. Try checking it for a potential mistake.
}

✅ Good:

void main() {
  var j = 1;

  for (var i = 0; i < 10; i++) {}
  for (var j = 0; j < 10; j++) {}
  for (var i = 0; j < 10; j++) {}
}
