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 'CompressionResult('
      'originalFile: $originalFile, '
      'compressedFile: $compressedFile, '
      'compressionRatio: ${compressionRatio.toStringAsFixed(2)}%, '
      'compressionTime: ${compressionTime.inMilliseconds}ms, '
      'isSuccess: $isSuccess'
      '${errorMessage != null ? ', errorMessage: $errorMessage' : ''}'
      ')';
}
