PopupExpression

Defines an Arcade expression within a pop-up. Arcade is an expression language that is supported across ArcGIS. It can be used to perform calculations, manipulate text, and evaluate logical statements. The expression can transform a list of attributes into engaging information for your audience. For example, to place a field value into a string of meaningful text you just need to use the Concatenate and Text functions. Explore Arcade's function reference for a full list of Arcade commands that offer a range of logical, geometry, math, and date functions.

Once you have constructed an Arcade expression, pass it to the PopupExpression.expression and specify a PopupExpression.returnType. Pass the pop-up expression to ExpressionPopupElement.ExpressionPopupElement to create an ExpressionPopupElement.
