Usage #

],
);

Define your output #
Just implement the output class. For example, below is an example crashlytics output.
class ExampleCrashlyticsOutput implements Output {
final FirebaseCrashlytics _crashlytics;

const ExampleCrashlyticsOutput(this._crashlytics);

@override
void log({
required Object? message,
required Level level,
required StackTrace? stackTrace,
required String context,
}) {
if (level.value >= Level.error.value) {
_crashlytics.recordError(message, stackTrace ?? StackTrace.current);
} else {
_crashlytics.log(message.toString());
}
}
}

Performance #
It is faster than a library like logger because it does not use the stack trace
for every log (only if specified). This results in faster logging when no stack trace is used.
