Dart native support

[guyluz11]

I would like to run Pytourch Lite on my server side that use Dart native.
Since we are using pigeon to generate the code, I am wondering how hard it will be to generate code for dart native.
Does pigeon even support generating dart native code?.

Sadly the binaries to run the models are each into android and iOS sdks,so pure dart version is extremely hard

[guyluz11]

I see implementations in c++ https://pytorch.org/cppdocs/ and rust tch-rs and maybe even c ATen.

Maybe we can generate it using pigeon or ffi

Pytorch lite is depreciated and the new package by pytorch is exectorch

The reason that I don't think of going through the effort is that mainly that, maybe when exectorch is stable I may switch to it and make it in cpp

In all ways will need to wait for dart native assets support to include the binaries in the dart build process

note if you want ffi i tried it already it had a problem with ios, this is why i switched back
https://github.com/abdelaziz-mahdy/pytorch_lite/tree/latest-ffi

and if you are making a backend or ci, python will be the easier solution in the usecase you mentioned

Cool ffi will be good.

I know python is a good option but I prefer my frint end and the back end to have the same programming language so if I have the option I will take it.
