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 'primary: $primary\n'
'secondary: $secondary\n'
'tertiary: $tertiary\n'
'neutral: $neutral\n'
'neutralVariant: $neutralVariant\n'
'error: $error\n';
}
