MetricCheck class

One metric's verdict against its recorded golden (regression gate). Every metric is lower-is-better; a metric with no recorded golden under ref or any is reported as noGolden (a check before the first record — warned, not failed).

Constructors

MetricCheck({required String metric, required String ref, required num measured, required num? golden, required num? limit, required double slack})

const

Properties

deltaPct → num?

Signed percent the measured value deviates from the golden ((measured − golden) / golden × 100, one decimal), null without a golden.

no setter

golden → num?

Recorded golden under ref or any, or null when none exists.

final

hashCode → int

The hash code for this object.

no setter, inherited

limit → num?

One-sided gate bound = ceil(|golden * slack|) clamped to ≥ 1. Null when there is no golden.

final

measured → num

Measured median of this run.

final

metric → String

Metric key (scenario id).

final

noGolden → bool

True when this metric was measured but has no recorded golden yet.

no setter

ref → String

Reference the golden was looked up under (falls back to any).

final

regression → bool

Regression: measured worse than the golden by more than the slack.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

slack → double

Slack fraction used for the gate.

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
