-Global properties are accessible across all pages of your app. They act as a utility function to accomplish a common task regardless of the type of app you are developing. 
+Global properties are **built-in variable**s in FlutterFlow that you can use across all pages of your app. These properties are predefined by FlutterFlow, meaning you cannot create or modify them yourself. They are designed to help you perform common tasks efficiently, no matter what type of app you’re developing.
