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() {
return 'KeyModifiers{shift: ${has(shift)}, alt: ${has(alt)}, ctrl: ${has(ctrl)}, superKey: ${has(superKey)}, hyper: ${has(hyper)}, meta: ${has(meta)}}';
}
