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() {
  if (!hasMetadata) return 'FileValidationResult($regionName: no metadata)';
  if (!exists) return 'FileValidationResult($regionName: MISSING)';
  if (!isValid) {
    return 'FileValidationResult($regionName: size mismatch '
        '$actualSize != $expectedSize)';
  }
  return 'FileValidationResult($regionName: valid)';
}
