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('Failed to rasterize a picture: $message.');
if (stack != null) {
buffer.writeln();
buffer.writeln('The callstack when the image was created was:');
buffer.writeln(stack!.toString());
}
return buffer.toString();
}
