The NullableType property of the SerializedProperty class provides the underlying type of a nullable property. If the property is a nullable type, this property will return the type that is being made nullable. For example, if the property is of type int?, the NullableType will return int.
Use the NullableType property to determine the base type of a nullable property. This can be useful when you need to perform operations that require knowledge of the underlying type, such as reflection or type conversion.
// Example usage of NullableType property
SerializedProperty property = ...; // Assume this is initialized
if (property.IsNullable)
{
System.Type nullableBaseType = property.NullableType;
// Perform operations with nullableBaseType
}
