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() => switch (this) {
unknown => 'Unknown',
critical => 'Critical',
low => 'Low',
normal => 'Normal',
high => 'High',
full => 'Full',
unsupported => 'Unsupported',
};
