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() {
if (width == double.infinity && height == double.infinity) {
return 'Size.infinite';
}
if (width == 0.0 && height == 0.0) {
return 'Size.zero';
}
return 'Size($width, $height)';
}
