Implementation

@override
String format(String message, StackTrace? stackTrace, LogLevel level) {
  String stackTraceStr = stackTrace == null
      ? _formatStackTrace(StackTrace.current)
      : _formatStackTrace(stackTrace);

  return _format(
    level,
    message,
    DateTime.now().toIso8601(),
    stackTraceStr,
  );
}
