Class ArcadeLabelExpression
An expression script using the Arcade language.
Namespace: Esri.ArcGISRuntime.Mapping.Labeling
Assembly: Esri.ArcGISRuntime.dll
Syntax
public class ArcadeLabelExpression : LabelExpressionRemarks
The Arcade label expression property must contain a syntactically correct Arcade script
expression. An example expression that combines text with a field value is
"State: " + $feature.State_Name.
Note that quotes are needed around the literal text. See https://links.esri.com/arcade for full documentation on the Arcade scripting language and its function library.
Any Arcade functions allowed for the Labeling profile can be used in a label arcade expression. Other functions (for example, FeatureSet functions) are potentially too slow to be used in a dynamic label evaluation.
Warning: If the expression attempts to use attributes which don't exist then no label will be produced.
This is distinct from the attribute existing but having a null or empty value,
which can form part of the produced text label.
