+/// The [ActionModel] class is a representation of an interactive action
+/// that a program can execute based on a user's interaction.
+///
+/// Each [ActionModel] instance contains a specific [ActionType], which
+/// determines the type of action that needs to be performed.
+///
+/// The class supports serialization and deserialization from JSON,
+/// allowing for easy storage, retrieval, and transmission of action data.
+///
+/// It is an abstract class, meant to be subclassed for specific types of actions.
+/// The specific action classes are determined by the [ActionType] enumeration.
+///
+/// This class also implements the Visitor pattern via the [accept] method.
+/// This allows for type-specific computations or actions to be performed
+/// on an [ActionModel] instance without the need for type checking or casting.
+///
+/// For example, the [ActionModel] class can represent various types of actions
+/// such as navigation, link, submit, setValue, setVariant, setVariable,
+/// callFunction, and callApi. Each of these action types can be handled
+/// differently based on the requirements of the application.
+///
+/// This design provides a flexible and extensible way to manage actions
+/// in response to user interactions.
