[Feature Request] Add event transformer to logger

[HazemSayad]

I was trying to extend logger and customize it but i found LogEvent was rigid and could be a great fix if only i was able to modify it somehow. Hence the request for an event transformer.

I imagined something like a simple function call like the below:

  Logger({
    LogFilter? filter,
    LogPrinter? printer,
    LogOutput? output,
    Level? level,
    EventTransformerCallback? eventTransformer,
  })

this issue is mainly a stub for the PR

Hi, maybe this would be simpler yet equally effective for your use case, please test and report back.

I pushed a patch to logEvent which would allow the following:

class CustomLogger extends Logger {
  CustomLogger({super.filter, super.printer, super.output, super.level});

  @override
  void logEvent(LogEvent event) {
    final e = event.message as CustomMessage;
    super.logEvent(_ExtendedLogEvent.fromLogEvent(
      event: event,
      tag: e.tag,
      shouldMask: Random().nextBool(),
    ));
  }

  @override
  void d(covariant CustomMessage message,
      {DateTime? time, Object? error, StackTrace? stackTrace}) {
    super.d(message, time: time, error: error, stackTrace: stackTrace);
  }
}

Hello, thanks for the quick reply. I honestly like your solution more. It has less api change and does the same thing.

For my use case, either ways i am extending logger to tighten the signatures.

I would like to use this change right away, do you have an ETA on when a new release with these changes will be made?

Do you want me to close my PR or you would like to do that?
