toString method
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();
}
