toString method Null safety

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 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

String toString() {
  return const [
    'RawSocketEvent.read',
    'RawSocketEvent.write',
    'RawSocketEvent.readClosed',
    'RawSocketEvent.closed'
  ][_value];
}
