No Output

[caelinsutch]

I'm getting no log output.

pubspec.yaml

environment:
  sdk: ">=2.1.0 <3.0.0"
...
dependencies
  logger: 0.9.1

main.dart

main() {
  var logger = Logger();

  logger.e("Logger is working!");
  print("logger");
}

"Logger is working" doesn't print, but "logger" does.

Note, running with dart --enable-asserts example/main.dart works. Is this required? If so, it should be noted in the documentation.

The default logger as you are using it uses the DevelopmentFilter (see https://pub.dev/documentation/logger/latest/logger/Logger/Logger.html). That filter doesn't log anything in "production" mode, this is defined as not using asserts. Running a program with the dart interpreter w/o arguments does not use asserts/run the program in production mode. The README explains this too: https://github.com/leisim/logger#logfilter

I hope this helps.

This was far, far too hidden, and we spent far, far too much time finding it. Thanks, will give this a try.

It's a strange construction though, do I really need to use a different filter depending on whether the app is in dev/prod? The default is DevelopmentFilter. Since we use a FileOutput, we very much want to log in production, so we can generate a log file for reporting in release.

Edit: Suppose we'll just stick to ProductionFilter for everything.

This indeed was too hidden and unexpected behaviour.
The main reason for using such a logger would probably be to get logs during production.

If I only want them while developing I might aswell use print everywhere.

Using ProductionFilter for everything now aswell.
