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() {
  final buffer = StringBuffer();
  buffer.writeln('Performance Report (${timestamp.toIso8601String()})');
  if (!enabled) buffer.writeln('Enabled: $enabled');
  buffer.writeln('Active Sessions: $activeSessions');
  buffer.writeln('Total Events: $totalEvents');
  buffer.writeln('Categories: ${categoryStats.length}');

  for (final entry in categoryStats.entries) {
    buffer.writeln('  ${entry.key}: ${entry.value}');
  }

  return buffer.toString();
}
