SchemaPropertyValue class

A property-value pair, e.g. representing a feature of a product or place. Use the 'name' property for the name of the property. If there is an additional human-readable version of the value, put that into the 'description' property.\n\n Always use specific schema.org properties when a) they exist and b) you can populate them. Using PropertyValue as a substitute will typically not trigger the same effect as using the original, specific property. See https://schema.org/PropertyValue

Properties

additionalType ↔ String?

//schema.org/docs/styleguide.html">style guide.

getter/setter pair

alternateName ↔ String?

An alias for the item.

getter/setter pair

description ↔ dynamic

A description of the item.

getter/setter pair

disambiguatingDescription ↔ String?

A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.

getter/setter pair

hashCode → int

The hash code for this object.

no setter, inherited

identifier ↔ dynamic

The identifier property represents any kind of identifier for any kind of SchemaThing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.

getter/setter pair

image ↔ dynamic

An image of the item. This can be a SchemaURL or a fully described SchemaImageObject.

getter/setter pair

mainEntityOfPage ↔ dynamic

Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.

getter/setter pair

maxValue ↔ int?

The upper value of some characteristic or property.

getter/setter pair

measurementMethod ↔ dynamic

A subproperty of SchemameasurementTechnique that can be used for specifying specific methods, in particular via SchemaMeasurementMethodEnum.

getter/setter pair

measurementTechnique ↔ dynamic

"mass spectrometry" or "nmr spectroscopy" or "colorimetry" or "immunofluorescence". If the SchemavariableMeasured is "depression rating", the SchemameasurementTechnique could be "Zung Scale" or "HAM-D" or "Beck Depression Inventory".

getter/setter pair

minValue ↔ int?

The lower value of some characteristic or property.

getter/setter pair

name ↔ String?

The name of the item.

getter/setter pair

potentialAction ↔ SchemaAction?

Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.

getter/setter pair

propertyID ↔ String?

A commonly used identifier for the characteristic represented by the property, e.g. a manufacturer or a standard code for a property. propertyID can be (1) a prefixed string, mainly meant to be used with standards for product properties; (2) a site-specific, non-prefixed string (e.g. the primary key of the property or the vendor-specific ID of the property), or (3) a URL indicating the type of the property, either pointing to an external vocabulary, or a Web resource that describes the property (e.g. a glossary entry). Standards bodies should promote a standard prefix for the identifiers of properties from their standards.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sameAs ↔ String?

URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.

getter/setter pair

subjectOf ↔ dynamic

A CreativeWork or Event about this Thing.

getter/setter pair

unitCode ↔ String?

The unit of measurement given using the UN/CEFACT Common Code (3 characters) or a URL. Other codes than the UN/CEFACT Common Code may be used with a prefix followed by a colon.

getter/setter pair

unitText ↔ String?

A string or text indicating the unit of measurement. Useful if you cannot provide a standard unit code for unitCode.

getter/setter pair

url ↔ String?

URL of the item.

getter/setter pair

value ↔ dynamic

The value of a SchemaQuantitativeValue (including SchemaObservation) or property value node.\n\n* For SchemaQuantitativeValue and SchemaMonetaryAmount, the recommended type for values is 'Number'.\n* For SchemaPropertyValue, it can be 'Text', 'Number', 'Boolean', or 'StructuredValue'.\n* Use values from 0123456789 (Unicode 'DIGIT ZERO' (U+0030) to 'DIGIT NINE' (U+0039)) rather than superficially similar Unicode symbols.\n* Use '.' (Unicode 'FULL STOP' (U+002E)) rather than ',' to indicate a decimal point. Avoid using these symbols as a readability separator.

getter/setter pair

valueReference ↔ dynamic

A secondary value that provides additional information on the original value, e.g. a reference temperature or a type of measurement.

getter/setter pair

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJsonLd() → Map<String, dynamic>

Serialize SchemaPropertyValue to JSON-LD

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
