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() {
  var lines = 'One or more exceptions has been occured while disposing bag\n';
  var i = 0;
  for (final ex in exceptions.entries) {
    lines += '$i ${ex.key}\n${ex.value}\n';
    i++;
  }

  return lines;
}
