Add support for dart native

There is an option to run a dart backend as also demonstrated here https://www.youtube.com/watch?v=P1XzbpeD2GY

I imagine that it will be very popular to use video manipulation on the server side.

Let's think of an option to convert this package to use Dart native.


Start by reviewing the package's current platform architecture and the linked Dart native example to determine what server-side support would require. Define the supported Dart native use cases and how video manipulation would work outside the existing platforms; the issue is done when that scope is implemented and documented.
