What does the function JsonUtility.FromJson require as a parameter to deserialize a JSON string?

The function JsonUtility.FromJson is designed to deserialize a JSON string into a corresponding C# object. To achieve this, it requires a class type as a parameter. This class type defines the structure that matches the JSON data being deserialized, allowing the function to map the JSON fields to the properties within the class.

For successful deserialization, the JSON string's format must match the structure of the specified class, including property names and types. This direct mapping is crucial for JsonUtility to create an instance of that class and populate its properties with the values extracted from the JSON string.

Other options, such as providing a file path, an int value, or a URL, do not align with the intended usage of this function, as those parameters do not convey class structure or are unrelated to the deserialization process. Thus, requiring a class type as a parameter is essential for the proper functionality of the JsonUtility.FromJson method.
