Above is the exception log, and below code runs well on dev build, using kotlin native code okhttp3 client also works

  get onchange => (str) {
        http
            .get(
                "https://anime-pictures.net/pictures/view_posts/0?&lang=zh_CN&search_tag=" +
                    str) //TODO
            .then((response) {
          return RegExp(r'img_cp[\s\S]+?src="\/\/([\s\S]+?)"', multiLine: true)
              .allMatches(response.body)
              .map((mt) => mt.group(1))
              .toList();
        }).then((List<String> urls) {
          print(urls);
          _updateWheel(urls);
        });
      };

My network is in good status. so, what's wrong here?
