cobalt_logging 1.5.0

Cobalt adapter for package:logging — sends the DI graph's events to a dart.dev Logger.

cobalt_logging

Adapter for package:logging, the dart.dev one, for Cobalt.

Not cobalt_logger. That adapts package:logger, a different package whose name differs by one letter. This one is for the dart.dev logging.

Logger.root.level = Level.ALL;
Logger.root.onRecord.listen((record) => print(record));

final scope = await CobaltApplication.start(
  root: const AppScope(),
  observers: [CobaltLogObserver(CobaltLoggingSink())],
);

package:logging routes rather than prints, so nothing appears until something listens — the two lines above are not optional decoration.

Levels

Cobalt	logging
trace	FINEST
debug	FINE
info	INFO
warning	WARNING
error	SEVERE

trace lands on FINEST rather than FINE because Cobalt's trace level is per-instance, and a graph of any size produces a lot of it. CobaltLogObserver also drops it by default; pass minimumLevel: CobaltLogLevel.trace to let it through.
