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 semVer = [major, minor, patch].join('.');

  return [
    semVer,
    if (preReleaseMajor != null || preReleaseMinor != null)
      [
        if (preReleaseMajor != null) preReleaseMajor,
        if (preReleaseMajor == null && preReleaseMinor != null) '0',
        if (preReleaseMinor != null) preReleaseMinor,
      ].join('.'),
  ].join('-');
}
