Warns when several returns inside a function body can be replace with a single conditional expression.

Example​

❌ Bad:

const _value = 1;

int? anotherOne() {
  final value = 1;
  if (value == 2) {
    return value;
  }

  return null; // LINT: Prefer returning conditional expressions.
}

✅ Good:

int? anotherOne() {
  final value = 1;

  return value == 2 ? value : null;
}

void correct() {
  if (_value != 2) {
    return _value;
  }
  final value = 1;

  return value;
}

void correct() {
  final value = 1;
  if (_value != 2) {
    print(_value);
  }

  return;
}
