Hi,
I want to port the engine to a new non-linux os(RTOS) platform and have several questions about that:

1. Can I port the flutter engine on the rtos?
2. If can , which system interfaces the OS must support for the flutter engine. You know the linux platform has a libc(glibc) to provide the interface for application to access the kernel's services. But in the non-linux OS, it doesn't support the entire libc functionality, such as fuchsia. Or it doesn't support libc. So what the exact system interface the flutter engine need is in new OS platform?
3. what’s the difference between "fml / platform" and “shell / platform” , why there has two platforms ?

Thanks,
