toString method

  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 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 StringBuffer buffer =
      StringBuffer('ProcessPackageExecutableNotFoundException: $message\n');
  // Don't add an extra space if there are no arguments.
  final String args = arguments.isNotEmpty ? ' ${arguments.join(' ')}' : '';
  buffer.writeln('  Command: $executable$args');
  if (workingDirectory != null && workingDirectory!.isNotEmpty) {
    buffer.writeln('  Working Directory: $workingDirectory');
  }
  if (candidates.isNotEmpty) {
    buffer.writeln('  Candidates:\n    ${candidates.join('\n    ')}');
  }
  buffer.writeln('  Search Path:\n    ${searchPath.join('\n    ')}');
  return buffer.toString();
}
