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 sb = StringBuffer();
sb.write('Affine:\n');
for (int r = 0; r < 3; r++) {
for (int c = 0; c < 3; c++) {
sb.write('\t${get(r, c)}');
}
sb.write('\n');
}
return sb.toString();
}
