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('Benchmark Comparison:');
  buffer.writeln('Value Size: $valueSize characters');
  buffer.writeln('Iterations: $iterations');
  buffer.writeln();

  buffer.writeln('Synchronous Results:');
  for (final result in syncResults) {
    buffer.writeln('  $result');
  }

  buffer.writeln();
  buffer.writeln('Asynchronous Results:');
  for (final result in asyncResults) {
    buffer.writeln('  $result');
  }

  buffer.writeln();
  buffer.writeln('Performance Improvement (Async vs Sync):');
  final improvements = getImprovementPercentages();
  for (final entry in improvements.entries) {
    final sign = entry.value >= 0 ? '+' : '';
    buffer.writeln('  ${entry.key}: $sign${entry.value.toStringAsFixed(2)}%');
  }

  return buffer.toString();
}
