fatal method
Logs a message with LogLevel.FATAL.
Use this for critical system errors that typically require immediate shutdown.
Example:
logger.fatal('Database corruption detected', tag: 'DB');
Implementation
@override
void fatal(dynamic message, {String? tag, Object? error, StackTrace? stackTrace}) {
listener.onLog(LogLevel.FATAL, message, error: error, stackTrace: stackTrace, tag: tag);
}
