v1.11.0

warning

has auto-fix

pro+

Warns when ++ or -- is used instead of += or -=.

Using ++ does not make it obvious that the underlying variable is actually being mutated, whereas += more clearly does (it's an assignment with an = sign).

Additionally, += is more convenient when changing the increment to a number other than 1.

Example

❌ Bad:

void main() {
  int value = 1;
  
  value++; // LINT: Prefer += or -= over ++ or --.
  value--; // LINT: Prefer += or -= over ++ or --.
}

✅ Good:

void main() {
  int value = 1;

  value += 1;
  value -= 1;
}
