[bug] one bug about Trace.terse #49

Closed Guang1234567 closed 2 months ago

Guang1234567 commented 5 years ago

Hello dev:

print('Stack trace 1 :\n ${Trace.format(s, terse: true)}’); get a wrong format result when i cut off the network of my phone in below code? Thanks.

Or maybe is not the bug, just dart print function can not ouput the whole StackTrace, just print a part of StackTrace? So how to print the whole StackTrace?

static Stream<SearchState> _search(String term, GithubApi api) async* {
    if (term.isEmpty) {
      yield SearchNoTerm();
    } else {
      yield SearchLoading();

      try {
        final result = await api.search(term);

        if (result.isEmpty) {
          yield SearchEmpty();
        } else {
          yield SearchPopulated(result);
        }
      } catch (e, s) {
          print('Exception details:\n $e');
          print('Stack trace:\n $s');
          print('Stack trace 1 :\n ${Trace.format(s, terse: true)}');
          print('Stack trace 2 :\n ${Trace.format(s, terse: false)}');
        yield SearchError();
      }
    }
  }

Console output:

This looks like a bug somewhere else, it looks like the string output was cut off during printing (or writing to a socket/fd etc.).

get a wrong format result when i cut off the network of my phone in below code

How do you expect the program to send the logs without a network connection?
