MetricDescriptor class

Constructors

MetricDescriptor({String? description, required String label, String? unit})

Returns a new MetricDescriptor instance.

Properties

description ↔ String?

Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
