Please add Windows to the example code

[flutterfromscratch]

At the moment, there are no existing resources showing how to use Pigeon with Windows. I've spent quite some time digging through GitHub issues and documentation trying to work it out, but there's nothing showing how it works.

If I work it out in the next few weeks I'll submit a PR 😊

Hey @flutterfromscratch, it's my understanding that the Windows API is still in flux. Moreso than the other experimental generators. I know less about it since my colleague is leading that effort. A good place to look would be the platform tests in https://github.com/flutter/packages/tree/main/packages/pigeon/platform_tests/windows_unit_tests. Here are the issues he has filed: https://github.com/flutter/flutter/issues?q=is%3Aissue+is%3Aopen+label%3Apigeon+label%3Aplatform-windows

Ah okay. While it's in flux, should we not use it? I understand that it's in an experimental phase, however, I don't mind trying to use it while it's at this stage to try to find possible issues. Is there a certain point at which the Windows functionality would be stable enough for examples to be written against it?

@flutterfromscratch, I asked Stuart and they said @HostApi generation should be fairly stable but he plans to change@FlutterApi quite a bit. So if that's fine with you, that'd be awesome if you tried it out.
