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() => 'APIMetric[$name]{${[
if (duration != null) 'duration: $duration',
if (n != null) 'n: $n',
if (description != null) 'description: "$description"'
].join(', ')}';
