running a script with an if statement checking an int equality

[Maksim Lin]

trying to eval this code:

void main() {
  print(calc(50));
}

int calc(int sumTo) {
  if (sumTo == 13) {
    print("unlucky number!");
  }
  int accum = 0;
  for (int i = 0; i < sumTo; i++) {
    accum = accum + i;
  }
  return accum;
}

using:

import 'dart:io';
import 'package:dart_eval/dart_eval.dart';

void main(List<String> args) async {
  final src = File(args[0]);
  final program = src.readAsStringSync();
  print(eval(program, function: 'main'));
}

Unfortunately produces the error below.
It seems to be to do with using the equality operator, as changing that to for instance a less-than operator allows the script to be eval'd without any errors.
