toString method Null safety

  1. @override
String toString ()
override

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 represetion.

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 (TiffImage.TAG_NAME.containsKey(tag)) {
    return '${TiffImage.TAG_NAME[tag]}: $type $numValues';
  }
  return '<$tag>: $type $numValues';
}
