Gets or sets the label expression script string.(Inherited from LabelExpression.)
The label arcade expression expects to hold a legal, Arcade script and to be read and evaluated by an Arcade expression interpreter. 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://developers.arcgis.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.
