LogService class

DataHubs logging solution.

This service is automatically added to any ServiceHost to provide logging functionality to other modules of the DataHub framework.

The configuration value datahub.log defines the initial log level. See enum values in LogLevel.

Messages can be logged by resolving the LogService and calling its logging methods.

  final log = resolve<LogService>();
  log.w('This is a warning!');

The default LogService uses a ConsoleLogBackend to write messages to stdout. If a different LogBackend implementation is required, simply pass it into ServiceHost constructor.

  final host = ServiceHost([
    ...
  ], logBackend: CustomLogBackendImpl());
