HString class
A string data type commonly used by Windows Runtime.
This class wraps the Windows Runtime memory allocation functions, allowing
the creation of HSTRING types with ease, as shown below:
final hString = HString.fromString('Hello world!');
In general, freeing the memory allocated for a HString when it is no longer used is not a concern, as the Finalizer automatically releases it for you when the object becomes inaccessible to the program. However, you also have the option to manually release its memory by calling the object's free method.
