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 'count: $count, '
'mean: ${mean}ms, sum: ${sum}ms, median: ${median}ms, min: ${min}ms, max: ${max}ms, p95: ${p95}ms, p99: ${p99}ms, stddev: ${standardDeviation}ms';
}
