Syntax
public class ArcadeLabelExpression : LabelExpression
Remarks

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 ArcGIS 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.
