toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  return 'PerformanceSummary('
      'hitRate: ${hitRatePercentage.toStringAsFixed(1)}%, '
      'avgFetch: ${averageFetchTime.inMilliseconds}ms, '
      'memory: ${memoryUsageMB.toStringAsFixed(1)}MB, '
      'queries: $activeQueries/$totalQueries, '
      'healthy: $isHealthy)';
}
