android – Flutter http get failing due to .substring – Stack Overflow

Weird one for you today…

  var url = Uri.parse(myRedactedUrl);
  try {
    http.Response response = await http.get(url).timeout(const Duration(seconds: 12)); // Timeout active
    print(url.toString().substring(0,70)); // <<<< Problem
    if (response.statusCode == 200) {
      decoded = jsonDecode(response.body);
      if (decoded['status'] == 0) {success = false;}
      if (decoded['status'] == 1) {success = true;}
    } else {success = false;}
  } catch (e) {success = false;}

The following http request completely fails if the print line marked ‘<<< Problem’ is included. Anyone have any idea why?

It only occurs when getting a sub string of the ‘url’, and I can imagine it might be actually altering that variable somehow, but this doesn’t seem intuitive and the sequence seems to suggest it shouldn’t matter anyway.

I can’t see why printing a substring of the url variable should affect the line above. I’ve tried removing the .substring and the problem disappears.
