toString method
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 buffer = StringBuffer()..write('CommandResult($exitCode');
if (output.trim() case final output when output.isNotEmpty) {
buffer.write(', output: $output');
}
if (error.trim() case final error when error.isNotEmpty) {
buffer.write(', error: $error');
}
buffer.write(')');
return buffer.toString();
}
