Consider making Dart stack trace available in events

[kuhnroyal]

I want to log some events to console in the beforeSend callback (for example from the runZonedGuarded integration) but the original StackTrace is not available and I can't find a good way to log the SentryStackTrace.

Does this make sense?

@kuhnroyal the exception should have its stack trace, eg (event.throwable as Error).stackTrace, it could be probably null or not an Error but it should be in most the cases.

the other option is not initing the SDK for debug builds, so the standard runZonedGuarded will log to the console.

does that help?

The event.throwable.stackTrace may work in some cases but not for errors in the isolate/runZonedGuarded integrations.

the other option is not initing the SDK for debug builds, so the standard runZonedGuarded will log to the console.

I know this would work but we capture a lot of stuff even in debug builds and use a custom logging integration (hopefully this can be replaced soon) to also log everything to console.

So basically all our code uses the logging package and gets written to console and converted to sentry events.
The only thing we are missing locally are the isolate/runZonedGuarded errors.

You might want to take a look (and leave feedback) at #631

@ueman Yes, I have seen this, that's why I am hopeful to remove the custom integration :)

[marandaneto]

we could technically call options.logger(args) to the integrations that capture events automatically, if debug is enabled, the dartLogger is assigned and it will print out using log from dart.developer, how does that sound?

[marandaneto]

RunZonedGuardedIntegration, IsolateErrorIntegration, FlutterErrorIntegration and FailedRequestClient would benefit

[kuhnroyal]

That sounds good, I could configure a custom SentryLogger then.

would you like to submit a PR @kuhnroyal ? adding such logs before calling hub.captureEvent?
