Logging large strings from Flutter

Question

I\'m trying to build a Flutter App and learning Dart in the process, but I\'m getting kind of frustrated when debugging. I have fetched a resource from an API and now I want

Answer 1

currently dart and flutter not supporting printing logs more than 1020 character (found that out by trying).

So, I came up with this method to print long logs.

static void LogPrint(Object object) async {
    int defaultPrintLength = 1020;
    if (object == null || object.toString().length <= defaultPrintLength) {
       print(object);
    } else {
       String log = object.toString();
       int start = 0;
       int endIndex = defaultPrintLength;
       int logLength = log.length;
       int tmpLogLength = log.length;
       while (endIndex < logLength) {
          print(log.substring(start, endIndex));
          endIndex += defaultPrintLength;
          start += defaultPrintLength;
          tmpLogLength -= defaultPrintLength;
       }
       if (tmpLogLength > 0) {
          print(log.substring(start, logLength));
       }
    }

}

hope that helped.

There is an open issue for that: https://github.com/flutter/flutter/issues/22665

debugPrint and print are actually truncating the output.
