logger property

The logger associated with this application context.

Subclasses should use this logger for all logging activities related to context lifecycle, configuration, and operations.

Logging Levels:

• TRACE: Detailed internal operations
• DEBUG: Configuration steps and lifecycle transitions
• INFO: Major lifecycle events (refresh, start, stop)
• WARN: Non-critical issues and deprecations
• ERROR: Critical failures and exceptions

Example:

@override
Future<void> refresh() async {
  logger.debug('Starting context refresh...');
  try {
    await super.refresh();
    logger.info('Context refreshed successfully');
  } catch (e) {
    logger.error('Context refresh failed', error: e);
    rethrow;
  }
}
